Polini have improved their 'Big Evolution' air filters to better exploit engine carburetion.
The air filter pictured above (Polini product code: 203.0159) features a 'truncated cone' shape, it's easy to fit and is suitable for Yamaha Minarelli horizontal engines equipped with a Polini PWK carburetor. The sponge has a high filtering capacity which traps all the impurities in the air while allowing air to flow efficiently through to the carb.
The above air filter (Polini product code: 203.0160) again has a truncated cone, it's easy to install and comes with a set of sleeves of different diameters to allow fitment with most of the popular carbs.
RRP for the above products: 38 Euros (£30.59) + VAT

For two and four-stroke engines and available in four sizes: 24, 26, 28 and 30mm these new universal carburetors from Polini comprise of a flat valve made of chromed light alloy that's more resistant to abrasion and wear. They're die-cast in light aluminium alloy with CNC machined centers, are easy to set up and offer great performance at every rpm along with greater pick up and acceleration whilst improving top speed by optimising the overall power output. The petrol level in the float chamber has also been checked in every carb to further ensure great performance and dependability.

This is
the latest version of the extraordinary nine roller variator kit from
Polini. The main improvement is a
lubrication system that features a case hardened nickel bush pin with a large
internal pocket that contains a special grease. The addition of a spring inside
the internal pocket allows the grease to distribute evenly on the pin even under
extreme racing conditions. There are other changes too like the new nylon and
aramidic fibre coated rollers to further help roller sliding. All in all, this
kit will not only improve transmission effectiveness, it will enable lower
service intervals too.
Available soon for Piaggio / Minarelli 50-94cc
engines.

Many of you will have already seen or used a Polini swivel manifold, we now have another to add to the collection. This particular one is for all Derbi and Minarelli AM6 engines. With a 35mm carburettor union diameter it’s aimed at those serious about speed as it’s designed for use with big flat slide carbs or Dell'Orto VHST 28mm etc. For anyone who hasn’t already seen these manifolds they come in two parts; an aluminium base plate and the inlet rubber itself. This configuration allows you to swivel the inlet rubber to point the carburettor any which way you want giving more carb / filter clearance.
PedMoto Air Filters: Along with many other PedMoto scooter performance parts that are currently in development PedMoto air filters have been designed and vigorously tested by us here at Adrenalin Pedstop. Currently there are two types available – panel filters and pod filters.
Panel filters: With their twin foam design and the specific porosities of foam that we’ve chosen, PedMoto panel filters allow for great air flow whilst improving filtration properties. With these being a direct swap for the original air filter they’re great for a small performance gain or a service. At present there are two different fitments in stock however the full range will be available to purchase within the next few weeks. The price is great too at ONLY £4.40.
Pod filters: We’re proud to present two different types of foam pod filter. First up is our exclusive race version that was developed during the 2011 BSSO race season. Made up of one single layer of foam this filter is very porous and allows the maximum possible air flow and performance. This compromises filtration however it’s ideal for anyone wanting the best possible power comparable to using no filter at all. Price £14.85.
We also do a road version of this filter that has a second layer of foam with a low porosity. The two layers enhance filtration properties making this filter ideal for everyday use in all weather conditions. Each filter comes in a wide range of union sizes and are priced at £14.85 each.

Comprising of 0.3mm carbon reeds, vulcanised rubber to withstand high working temperatures and a fixing plate machined from solid anodised aluminium this new improved Polini reed valve for Big Evolution Piaggio engines offers more air, more mixture and more power. Suggested assembly with a 24, 26 or 28mm carb.
Polini's new cylinder kit for 4T Yamaha X-MAX and X-CITY 125 / MBK Cityliner 125 grants great performance and faster acceleration through the rev range making overtaking easier thanks to the fast power delivery of this kit. The kit comes together with a pressure regulator, it's easy to fit and has been calibrated to suit the original exhaust system. By increasing the fuel pressure in the injection system this eliminates the use of the electric gear case thus increasing the power and torque of your scooter.
Technical Features
Made in Italy, this Polini cylinder kit has a 63mm bore and a displacement of 182.66cc. The displacement improves the power output of the scooter with a 11,5:1 compression ratio. The cylinder is cast in light aluminium alloy. The liner with Nickel-Siliceous coating improves the sliding of the piston and resistance to wear and abrasion. The kit includes the new SLS (Single Layer Steel) head gaskets made of flouride techno-polymers that are resistant to high temperatures. The piston is die-cast at high siliceous content with 'omega' design. This reduces thermal expansion and slack. Two special rings and one scraper ring are included with the piston. Polini's special piston dome design also improves the compression ratio.

We're keen advocates of Polini performance parts here at Adrenalin and for good reasons. If you've been considering purchasing any of their latest Big Evolution products then the following should be of interest.
Adrenalin Pedstop's 27.7hp Polini 94cc Piaggio Zip SP
Polini's Big Evolution - A New Chapter in Scooter Tuning
2010 saw the release of Polini’s range of Big Evo kits for 50cc Piaggio and Minarelli engines intended solely for competition use. The product range consists of 70cc, 84cc and 94cc configurations created from a selection of cylinder and crank combinations. With a brand new cylinder design and a full range of components to complement the kit, Polini weren’t hanging around and were going all out to match the constantly evolving range of products that surface on an annual basis for these popular engines.
2010 brought home great results for us using the Big Evo 70cc engine in the UK BSSO series with our rider Josh Brown who won races and set new lap records including a new lap time at the Three Sisters racetrack in Wigan. And for the second year running Josh was able to take the BSSO championship and be crowned champion once again. The engine in Josh’s Zip was originally supplied by Polini as a fully built race engine. Further enhancements were made by us in conjunction with Darrell Taylor at 50ccTuning through ongoing development and adjustments to the performance of the engine to suit UK racetracks – bear in mind that the engine was originally set up by Polini technicians for use on the shorter Italian circuits.
Adrenalin's Polini Big Evolution 94cc Piaggio Zip SP Race Bike
2011 comes as a new year and with it the feeling of trying something new, so out came the Big Evo 94cc engine with a view to running it at a race meeting or two. Currently the 94cc engine can be seen fitted to our shop demonstrator for all to drool over.
The Big Evo 94cc Piaggio configuration comprises of a 52mm cylinder kit and a 44mm long stroke crankshaft giving an actual capacity of 93.39cc using the ACU formula (bore x bore x stroke x 0.785). The build started out with a major shopping list of components and includes a brand new set of crankcases. After seeing the odd case fail in the past, the decision to use new casings was a no brainer coupled with the fact that the engine has to be machined out to accept both the crank and cylinder – the most powerful and highest torque producing kit around. The crankcases also benefit from additional strengthening thanks to the new bolt-on Polini Torsen WD which reduces engine flex by making the casing dual sided.
Keep an eye on our blog... In future blog posts we'll take you through some of the engine work including crankcase preparation, additional porting work and water pump assembly.
Now in stock from Athena are the long awaited 183cc cylinder kits for Yamaha 125cc 4T learner legals. They fit Yamaha YZF R125’s and WR125’s, both great looking bikes but both lacking in the power they deserve. The kit takes the capacity up to 183cc with the new aluminium nickel-carbide plated barrel and cast-lite piston. Also included in the kit is a new ECU that remaps the rpm curve bringing power straight in at 5000 rpm and holding out right through to 10500 rpm. The dyno shows a peak power of 17.1 hp at just under 9000 rpm.
Grab yours while you can as these have been long awaited in the UK so we're expecting they'll go pretty quick being the only part available for these bikes that will give any significant gains. We also now stock pistons and top end gasket sets for these kits, here are the product codes and links:

If you're looking for performance upgrades, then a worthwhile consideration for engines fitted with a Piaggio air cooled engine are the following Athena parts:
Piaggio air cooled engines (e.g. Piaggio Zip / NRG)
The Athena HP 70cc aluminium sports cylinder kit provides very useable all round performance throughout the rev range making it perfect for the street. The porting and quality of this kit is excellent and it's also very durable. This particular kit features a single piston ring, carbon fibre reed petals and a bunch of gaskets. Fits all Piaggio air cooled engines.
We recommend using a bigger carb of 17.5mm or above, however this kit will still work fine with the original carburettor with a jetting increase of 10-15% along with a performance exhaust system.
This is the Athena HPR Racing 70cc cylinder kit from Athena. Like the Athena HP 70cc cylinder kit, the porting and quality is excellent and again, very durable. The HPR Racing kit features a revised port layout and flat top piston for added power. The HPR kit is higher revving than the HP kit and requires a suitable exhaust like the Yasuni C16 or Doppler RR7 for example. You will also need to use a suitable carburettor of 17.5mm or above, however the kit will work with the standard carb with a jet increase of at least 10-15%. Included in the kit are carbon fibre reed petals and a bunch of gaskets to alter squish.
The Athena Platinum series of drive belts are made in Japan so you can expect the same quality and performance as Polini drive belts. Made from reinforced Kevlar, Athena Platinum drive belts are also extremely hard wearing. Please note that Kevlar drive belts require around 100 miles to wear in.
Increase your revs with an Athena unlimited CDI unit. This CDI is designed for race use and once fitted will remove all the barriers of the standard CDI and allow your scooter to be unleashed with an unrestricted unlimited revs unit.
Italian company Athena produce a range of high quality performance parts for a wide range of scooters, too many to list all at once here. If your scooter has a two-stroke Minarelli horizontal liquid cooled engine then the following Athena products are well worth a look at:
The porting and quality of the Athena HP 70cc aluminium cylinder kit is excellent, it's extremely durable and therefore ideal for road use. Included in the package is a single piston ring, carbon fibre reed petals and a bunch of gaskets. This kit is suitable for all Minarelli horizontal liquid cooled engines.
Like the HP kit from Athena the HPR Racing 70cc cylinder kit is also great quality and very durable. The difference with this kit is that it features a revised port layout and a flat top piston for added power. It's also a higher revving kit and therefore requires a suitable exhaust such as the Yasuni C16 or Doppler RR7. This kit will work with a standard carburettor with a jetting increase but to make the most out of it we recommend fitting a 17.5mm carb or bigger. Included in the kit are carbon fibre reed petals and a bunch of gaskets.
Athena's Platinum series of drive belts are made in Japan so you can expect the same quality and performance as Polini belts. Made from reinforced Kevlar Athena Platinum drive belts are extremely hard wearing.
Increase your revs! Intended for race use, once fitted this device will remove all the barriers of the standard CDI and allow full control of your scooter's power - unrestricted. Fitment is for models without a catalytic air feed pipe into the original exhaust system.
Athena produce aftermarket parts for a wide range of scooters and are a good option if you want good power increases and reliability. Here we've put together a few suggestions for getting the most out of a two-stroke Piaggio liquid cooled engine:
Athena HP 70cc cylinder kit
The Athena HP 70cc aluminium cylinder kit provides very useable all round performance throughout the rev range making it perfect for the street. This is an extremely durable kit and the porting and quality is excellent. This particular kit features a single piston ring, carbon fibre reed petals and a bunch of gaskets for squish etc. Fits all Piaggio liquid cooled engines.

Polini Motori have been around since the 1940s building and tinkering with mopeds and scooters. They have very extensive knowledge and this shows as they've grown from a small family run business to a very reputable international company.
Based in Italy, the home of big scooter brands like Piaggio and Gilera, Polini produce a huge range of tuning and performance parts for scooters like the popular Piaggio NRG, Gilera Runner plus many others. Their product line ranges from scooter exhaust systems and 70cc cylinder kits through to brake discs and clutch kits. Polini's most popular products are the Evolution range which are high-end race parts designed for the track. The knowledge and experience that Polini have gained over the year gives them the opportunity to excel in every aspect of scooter racing including holding their own racing series, the Polini Cup, over in Italy racing with the likes of Piaggio Zip SP and NRG liquid cooled scooters.
Here at Adrenalin Pedstop we stock almost every scooter related product available from Polini for a range of scooters like the Gilera Runner, Gilera Ice, Piaggio Liberty, Piaggio Typhoon, Piaggio Zip, Piaggio NRG, Yamaha Aerox, Yamaha Slider, Yamaha Neos plus many more. Our most popular sellers being Polini transmission parts like variator kits, Kevlar belts and clutches. We currently hold the 2010 UK BSSO Championship title which was achieved on a Piaggio Zip SP fitted with a array of Polini Evolution parts and piloted by Josh Brown.
Italkit cylinders are produced by Italy's legendary Gilardoni factory so as you'd expect they benefit from high end manufacturing which means great reliability and performance. This particular kit comprises of a two piece head and aluminium barrel with nikasil plating along with a Vertex single ring piston thus enabling reduced friction and heat transfer. There are six port transfers in this one and an exhaust port configuration similar to the Polini Evolution line up:
As this kit is compatible with Minarelli horizontal liquid cooled engines it can be fitted to a wide number of scooters including: Aprilia Area 51/Rally 50 LC/Sonic LC/SR 50 LC 1994-99, Bennelli 491 LC/K2 50 LC, Beta Ark LC/Eikon 50, Italjet Dragster 50, Malaguti F12 Phantom 50 LC, Malaguti F15 Firefox/Mach-G LC/Nitro 50, Yamaha Aerox 50/JOG RR LC/Zest
To get the best performance we recommend fitting a bigger carb, however good results can still be achieved with an increase in jetting and a good exhaust system.
