Hallo friends.
I have a new problem with my EVO 1340 with chain (no belt).
I have to match my front sprocket with my rear sprocket (51 teeth).
How many teeth is the most universal sollution (22,23,24) ?

 

Was your Stock setup a 32/ 70 if so then that was a 2.18
A 23/51 would be a 2.21 which is your closest option
A 24/51 would be a 2.12 which is a little taller which means not as much torque pulling away from a stop but lower rpm's on the highway.

 

OK. Thanks. I will test it - 23 x 51
I will write soon.

 

Maybe it was the wrong way to do it, but I changed the rear sprocker by 2 teeth. I unfortunately don't remember the rpm before, but the after is 3000 rpm at 70 mph.

OOps! sorry. My bike probably doesn't apply. I still have the 4 spd tranny.
