Hello all - first post here. I am re-gearing my 02 DR650 Supermoto for the upcoming riding season. I originally changed over to a 44t rear sprocket with the stock countershaft sized replacement front sprocket but now I find this combo geared way too short after some of the engine/carb mods done to my bike (which is 100% street ridden). I am looking to go back to either a 42t stock rear or maybe even a 41t rear. I prefer aluminum but wouldn't rule out a steel replacement. There is a VERY limited aftermarket selection of rear sprockets for the dr650. I noticed the other DR models seem to have a better selection of rear sprocket choices. Does anybody know if there is any inter-changeability amongst the DR models for rear sprockets? If there was it would open up a few different options for me to choose from. Thanks in advance for any help - I tried the SEARCH feature but didn't find an answer to this question.
