Polini Hi-Speed Evolution Variator Kits

Polini are well known as the market leaders when it comes to transmission components and their latest Evolution Hi-Speed kits are sure to set almost unbeatable targets for the nearest, but distant competition. The benefit of 9 rollers has proved a success on and off the race track over the last few years and now Polini have added some exciting improvements.
Under hard use variators generally increase in temperature which can make rpm drop off due to belt travel being delayed, because of this transmission becomes less efficient. Thanks to a new patented lubrication system from Polini the cannon bush is constantly greased which not only lowers temperatures but allows for perfect variation all of the time under extreme use. The rollers have also been treated to a new coating made form a mix of nylon and aramid fibres to further reduce temperature and roller life.

50cc road tuning suggestions for Minarelli horizontal LC engines

Within the world of scooter tuning today there is a big selection of tuning parts available. This may leave you a little stuck when trying to choose the correct parts that actually make your scooter more useable. So we've put a few suggestions together to help you get the best reliable everyday road performance from a 50cc scooter using reputable parts that work well together. The following list applies to two-stroke 50cc scooters fitted with a Minarelli horizontal liquid cooled engine:

MINARELLI HORIZONTAL LIQUID COOLED ENGINES

For Minarelli horizontal liquid cooled engine scooters such as the Yamaha Aerox, Jog RR, MBK Nitro, Mach G, Malaguti F15 Firefox, Italjet Dragster etc. we recommend the following parts:

Cylinder Kits: The Stage6 Streetrace 70cc kit is a cast iron kit that gives very useable bottom end power which is perfect for whizzing around town or practicing wheelies. Alternatively the Italkit aluminium 70cc kit will provide quite a bit more power but higher up in the rev range, perfect for all you speed freaks.

Exhaust systems: Again the Leo Vince TT is the best budget all round performer. The Tecnigas Trek or Artek K1 will see better power gains and release more of the 70cc kits potential. For anyone using a high revving aluminium road going cylinder then the Yasuni C16 is a must for anyone serious about speed.

Variators: This is the most substantial upgrade for any Minarelli engine as the standard article is very poor. The Polini 6 or Polini 9 roller variator kits are very easy to set up and give very consistent performance. Also the Doppler S2BR works really well on the Minarelli engine as it raises the rollers to 19x15.5 rather than the standard 15x12's.

So far we've mentioned the three main upgrades necessary to up the power of your ped. A carb upgrade and gear kit will further boost performance for anyone who has a larger budget available:

Carburettors: Minarelli engines normally have around an 11.5mm standard carburettor. For everyday use on the road we recommend a 17.5mm carb as it’s still fairly compact so therefore fits into the cramped space it sits. The Polini 17.5mm carburettor is made by Dell'Orto and can be easily set up for the original air box or a sports foam filter.

Gear Kits: Gear kits increase the gear ratios resulting in an increase in top speed. Top Racing 4 part kits come pre-pressed for easy fitting. Polini gear kits have undergone extensive testing to give you the best ratio for use with 70cc cylinder kits.

Stage6 sub-frame kit / Stage6 air filters

Stage6 sub-frames for Yamaha Aerox / MBK Nitro are now in stock. Fitting this part allows you to bring the carb up over the back wheel for better optics and performance. If you own either of the above scooters you'll know the cramped conditions your carburettor and filter suffer day in day out. With the Stage6 sub frame this can be thing of the past. It also allows the swing arm to move slightly to aid handling on the track.

Stage6 sub-frame product code and link: AD/S6-9916605

Stage6 sponge filters look great with their bright colours and Euro design. Offering excellent filtering performance due to two layers of foam with different porosities, each filter comes with different sized reducers so they can be fitted to pretty much any size union carburettor. Perfect for Aerox owners who have just purchased the above sub frame kit, combine one of these filters with a Piaggio straight inlet manifold and the results are you have one very trick looking ped with performance gains to match.
