March 25, 201313 yr Evening all, I have had a look on the www., but I cant find the answer to this simple question.... what is the standard gearing on the 2005 250 pro? mine has 10 42 on it and wondered if that was correct or if it could be improved upon. Thanks Andrew
March 25, 201313 yr I think standard is 11-42 Mine is running 10-43 but its personal preference thing.

March 25, 201313 yr 10/41 or 10/42 is generally best,standard 11/42 gives 1st that is still too high and 4th is too much on a 250 unless its really slippery
