thanks for your comment, we can push it more further and add more mods but not yet confident how reliable the engine can take, they still need to prove it has engine quality and lifespan like that of japanese designs. plus the ECU is so restricted on these bike,. give it more a couple of years to prove itself then we can push it to it's real limit. you can Subscribe to be able to see it in the near future, full mod and tune. ride safe -Bong
It's by engine design, 270 degree crank like in this 450sr is more torque-y. More midrange, than 180 degree crank in the ninja 400. More top end power.
