16T Front sprocket. 2018 DL650XT
Went up one tooth from OEM 15T to a 16T front sprocket. RPMs dropped 250 in 6th gear.
Now turning 4800 at 70mph and 4050 at 60mph.
Remains to be seen if my mpg improves. Not necessarily a given as it takes higher HP to push the higher gearing.
Acceleration still feels OK, although physics says it's been reduced some.
So a little less buzzy, and less wear on the engine, tranny, and chain.
sprocketcenter.com has one that also has the rubber damper on it.
Removal was difficult. Put the bike in 6th, and had the wife sit on it and step on the rear brake. My 18V DeWalt electric lug nut gun took the nut off easily, but it was a bitch getting the sprocket off with the chain on it as there is very limited room between the sprocket shaft and the clutch housing. Same thing for installation. Just have to keep fiddling with it. The service manual says to take off the nut and just remove the sprocket with no mention of having to take off the chain, so go figure......
