Hi all, My 2018 Tiger 800 XCx is revving 5000 rpm @ 70 mph (6th gear). Most of my daily commute is around 70 mph and I find 5K revs just a bit too much. Is there a way to calculate what sprockets I need (front / rear) to get that 70 mph at 4000-4500-ish revs? Thanks!
Gleekzorp. I am sure you will have one of the more intelligent inmates along soon to help out. Myself I would try one bigger toot to the drive sprocket. Ride Safe Joe.
Ah, I just found out about www.gearingcommander.com; the user interface is a bit outdated, but it does give you an awesome lot of information on sprocket sizes, wheel sizes, rpms and speeds. Have fun!
Gleekzorp. Now you are rocking. Go for it. Me I need a translator for that stuff. I am surprised some of the wiser more brainy peeps have not come aboard yet. Maybe having their meds late tonight. Regards Joe.
The hidden point is do you have the horsepower or more importantly the torque, at those revs, to pull these gear ratios? Don't forget wind, incline, load, pillions etc. If you know the final drive ratio ( front and rear sprockets) plus the primary drive ratio ( crank sprocket to clutch basket) plus the 6th gear ratio then it's a straightforward calculation
One tooth higher front sprocket never mind using calculation bumph,buy a good qaulity sprocket don’t go for cheap tat.
I have used gearcommander.com Changer the front sprocket down 1 and the rear up 2 The pull away is awesome at the sacrafice of top speed, I never go near the high end anyway and prefer the smoother get away If I was commuting on motorways I would have gone the other way and up 1 front and down 1 rear Looking at the chain to sprocket ratio wear, the same chain link going over the same tooth is so low that hopefully wear is greatly reduced too
