Here is the kit ATHENA RACING for YAMAHA MT 125cc 4T from 2015 - 2016. This kit has a cylinder - Ø63mm piston which offers no less than 182,7cc real engine capacity!
With its high compression piston, the compression ratio goes to 11.4: 1 for even more performance! This kit must be used only with SP98 gasoline!
Banning the SP95. The maximum power goes from 14.7 to 17.2 hp! It's huge on a small engine. Your 4T engine in addition to being more enjoyable to drive, more powerful, more torquey, will be more full on the beach! Finish the little hollow engine!
What is even more interesting is that the power gain is present at low speeds (see curve) and the switch is moved up to 10 9000 rpm against 10 000 for the origin!
The case therefore pushes the breaker, but it also takes the parameters of the injection mapography. It therefore offers the right AFR setting, but allows a boost in performance since it enlarges the power range!
This kit is of very high quality, aluminum, processing, manufacturing processes, everything is at the top! Made in Italy from the case to the piston passing through the joints, segmentation ... Everything is developed on bench by Italian engineers.
We recommend this kit with : SP98 or more only, sport exhaust system without catalyst like TURBOKIT or ARROW , sport air filter!
