I'll ask the guys in Zaltbommel!One more time
so with 15 43 you had no more problems (gear indicator error & not wanting to shift down) Still funny that you can manipulate it that wayWhat ever you do to the ECU is not going to fix the fact that the engine was designed for use with a 15t front sprocket. They put the same engine in the V2 Streetfighter but fitted it with a 45t rear sprocket as standard. So the V2 being more track focused was fitted with a 43t rear - if you are looking to make your V2 more street friendly (usable around town) then do as I did and change the rear to a 45t. I think it rides way better, acceleration is improved at the loss of some top speed.
A V2 built between 2020 and 2024 as standard has a 15t front and a 43t rear. Keeping a 15t on the front and swapping to a 45t rear there are no problems - all is good.so with 15 43 you had no more problems (gear indicator error & not wanting to shift down) Still funny that you can manipulate it that way
