Hi All
I know its a very late reply to this topic, but i have only just joined, i am interested in this topic as i am currently trying to make my 2015 sherco St 300 have a more usable 1st and 2nd gear, so was contemplating changing to a 11T front sprocket, and keeping my rear as standard 42, which i guess takes my ratio from say 4.2 > 3.81 which is about 10% i believe, but since the sherco runs a 5 speed box and say a beta evo 300 runs a 6 speed, but is running the same gearing 11T 42T is the ratio really the same ???? also i was told moving up one tooth on the front, will make my 1st gear into say 2nd and so on, but if the difference is only 10% surly thats all the difference will be is only 10% longer gearing , any in sight would be great and thanks to all in the previous posts.
regards Dan
