DR650 Gearing Question

Recommended Posts

Have been tinkering with the idea of getting a 14t sprocket for the front and a larger for the rear. http://procycle.us has the option of a 14t and a 46t for the rear. The wiki has mentioned going up to a 52t on the rear. http://dr650.wikia.com/wiki/520_Conversion

Has anyone put one that large on the rear? Am I going to get really bad gas mileage by going this large? Is the extra power worth it? I do ride highways a lot is this going to have the rpms screaming at highway speeds?

I am guessing yes, and that's probably why Procycle only offers the 46t for the rear. Any thoughts or ideas?

Haven't done anything else to the bike, yet. Will be re-jetting, pulling out snorkel, and replacing the exhaust. Will the 46t and doing this give it the extra thrust at take off I am looking for?

overall looking for a better off road experience and usually just ride the highways to get off-road...

i put the 14 tooth front sprocket on, and did the airbox mod, re-jet, and FMF Q4 exaust, big difference. still good on the highway, first and second gear came alive, very impressed. with out the re-jet and air box mod, i dont think it would be as impressive, (but the front sprocket was the cheapest performance mod). just try the front first.

Thanks. I found this site http://www.gearingcommander.com/ . It helps to calculate the top speed and rpms. pretty handy. to change from 15/42 to 14/46 really lowers the top speed. from about 98 to 83 and riding at 65 mph would have the rpms pretty high... may just get the smaller front or swap out both and have 15t front for when i do long road trips...

Not sure when, but at some point a larger rear will cause issues with the chain guide

I have a 48 on the back and the guide was being taxed so i went to the adjustable guide and it works great :thumbsup:
