My ride is a '03 CRF450 and I just love it. But looks like its time for me to get new sprockets and chain. Just wondering what a 51 tooth rear sprocket will do. Is there any noticeable gain of power/harder acceleration, much more shifting or not. Those of you who have tried it please help me out, what you liked/disliked. And, if you have tried any other rear sprockets please let me know. By the way, over 80% of my riding is motocross.
