malossi aerox

With many of the Euro 4 50cc 4T scooters being heavily restrained in performance by the new regulations, Italian tuning specialists Malossi are constantly developing new parts for those machines. The latest products available from VE (UK) add a cylinder kit and ECU for the Yamaha Aerox & Neos Euro 4 2018 onwards machines.
Malossi 66cc cylinder kit (YM313579): The new 66cc cylinder kit is manufactured from an aluminium alloy with a high content of silicon which has been machined on high precision CNC machines with a tolerance of just 0.05mm. Technical features include, recalculated heat exchange surfaces for more efficient cooling, ultra compact lightened and reinforced piston kit, and low friction piston rings. The cylinder kit must be used in conjunction with the Forcemaster ECU (YM558370).

Malossi Forcemaster ECU (YM558370): The Forcemaster ECU can be fitted to machines with either the original cylinder or Malossi’s 66cc cylinder kit by utilising one of the 4 inbuilt maps. The ECU lifts the rev limiter by 1300 rpm from 9200 to 10500, giving a substantial increase in performance when paired with the Malossi cylinder and noticeable improvements in performance with the standard cylinder.
