Airsal 125c cylinder kit for Honda S-Wing 125 etc.

This may look like a replacement barrel from Airsal however with the Nikasil plated aluminium barrel and redesigned flat top piston to increase compression you will also see a small HP and torque gain throughout the rev range. Like all Airsal components the quality is top notch to ensure durability is retained and it’s a fraction of the price of purchasing the original part from a main dealer. Suitable for Honda 125cc 4T engine scooters like the Honda Dylan, Pantheon, PS 125i etc.

New Polini Cylinder Kit for Yamaha X-MAX and X-CITY 125 / MBK Cityliner 125

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.

Athena 170cc cylinder kit for Honda CBR 125

The Athena 170cc kits are now in stock for CBR 125 models. We are stocking two kits, one for injection models and one for carburettor models. Both kits feature aluminium nickel-carbide barrels and cast-lite pistons. The kit for injection models comes with a new ECU that changes the rpm curve bringing power in at 6000 rpm right through to 13000 rpm. Peak power on the dyno comes in at 16.8 hp on injection models, unfortunately we don't have any information for carburettor models as of yet but expect similar gains but not as low down the rev range. These kits are one of the very few parts for CBR 125's that make any real power increases. Spare pistons and gasket sets are also in stock.
