Himalayan Gearbox Sprocket.

Hi all. Really enjoying my Himalayan and generally for the A & B roads I generally prefer, a cruising speed of 60 mph suits fine, though for occasional motorway sections, a little more relaxed 70 mph would be nice.. Has anyone tried experimenting with replacing the standard 15 tooth gearbox sprocket with a 14 tooth to enhance cruising speed accordingly?

Surely, if you replace the gearbox sprocket with one with fewer teeth it will have the opposite effect to giving you a more relaxed 70 mph. :o

Thanks Wheaters... you're right of course... I'd need to go up a tooth for improved top speed. So... Anyone done that please..

Yes, I have installed the 16 tooth sprocket. Dropped the rpm approximately 400rpm at highway speeds. Bike pulls it fine.

Great.. Thanks Gaura.. Any comment on how the change in gear ratio affects the bike at slow speeds.

I changed to a 16 on our Himalayan ( well its the wifes really ) and anyway - made no difference to low speed and pulling away in first and has greatly improved cruising speed.

I'm on the brink of getting a Himalayan and the only thing stopping me is the reported low cruising speed (someone quoted 55 mph which is a bit low for 24 bhp) I do understand that it's designed as an off-roader to some degree so this may be reflected in low gearing.
With the bigger sprocket do you get a genuine 60 cruising speed and a top speed of (say) 75?
I don't want to go any faster than that but I do want to keep up with the traffic.
Has anyone fitted the 17 tooth?

My Himi is still fairly new 1000miles and cruises at 65mph and will get up to 70+ for over take.

Unless you are going for the big bore kit and upgrade ECU - I would say that the 17 is a step too far, the engine pulls a 16 in top ok but doubt if a stock one would.
