During this past summer’s riding I decided that a change of overall gearing on my 2020 CMX500 was needed. I had realized that when taking off from standstill in 1st gear at stop-signs or lights I usually needed to change up to 2nd too quickly. Taking off from 2nd also usually needed a bit of clutch slipping. So I decided upon raising the overall gear ratio a tad, via the gearbox chain sprocket. Stock is 15-tooth, and I found that 16-tooth versions are readily available, in straight steel and rubberized versions. I decided upon the rubberized version (sourced from the UK), which would give a 16/15 increase, or 6.7%. I managed to fit the new sprocket and do a short test ride before it got too chilly to ride, up here in Montreal. I was impressed with the change, which took only an hour to implement on the bike. The trickiest thing was the removal and refitting of the plastic chain sprocket cover ! The bike seemed slightly smoother and quieter, no doubt due to the rubberized sprocket, and the gearing change was just what I was looking for. No strange amber or red lights turned up on the dash, and the chain adjustment ended-up well within range at just 5mm forward on the rear axle. Since road speed (speedo) drive is taken from the gearbox, the speedo will read proportionately low, but this worries me not. Cruise speed rpm will be a little lower too. My source for the sprocket was Brooks Barn Motorcycles | eBay Stores in the UK, but there may be other providers in N/A.
