crf450guy how does the power feel with the 51 tooth rear sprocket on your '04 crf? On some websites they say that a 50 tooth sprocket would be too much for some riders. I wonder what a 51 tooth sprocket will do??????
I ride hare scrambles with alot of tight woods...I also put a 13oz flywheel weight on it. The front tire LEAPS off the ground in about any gear which i like for obstacles like logs rocks etc...MOTO CROSS guys probably wouldn't like it much...Some of our races have open grass track and i never feel like I'm missing top end speed.
But i am a C class rider so an AA guy might feel different....
51's are ok but they are too short for sand/deep loam. Seems to spin too much and topend is not what it should be. I tried a 49t and it was ok although it was still a little tall for tighter tracks. Put the 50t on and I seem to be happy. We ride on everything from really tight/small/wussy tracks to fast/open/loamy tracks. I wanted something that would handle both without having to swap sprockets all the time. It's an individual preference. For offroad stuff I'd probably look into a flywheel weight like crf450guy is doing.
