sprockets for BMW F650GS

canuck479 · 06-12-2008, 04:18 AM

Does anybody know a source for different size sprockets for the F650GS I am looking to get the RPM a little lower at highway speeds.

I have just replaced my sprockets and chain.
I used JT Sprockets.

I got my rear 45-t sprocket here http://www.sprocketspecialists.com/SprocketMain.aspx
Front 17-t sprocket here http://www.bmwsantacruz.com/main.html

Very good set-up for highway. My .02

How many miles do the sprockets and chain usually last on highway use?

Has anyone ever tried any of the lifetime guarateed titanium sprockets?

I wonder if they even fit our bikes.

That's going to depend on many factors, including chain quality and your cleaning/lubrication habits.

I've seen sprockets that were shot after a few thousand miles, and I've seen sprockets that have lasted 25K miles+ on these bikes. My current set probably has 10K miles on it and everything looks new (I've used both Chain Wax and currently ATF)

Never tried a Titanium sprocket.

Just ordered a 17 tooth front from http://www.powersportsuperstore.com.
Still trying to find a 43 tooth rear.

if you cant find the right tooth ratio sprocket specialist or specialties cant remember the name correctly can custom make any size you want. they also have sprockets ready in a few sizes for the dakar. i have a 14 and 15 tooth front from them since i wanted more offroad gear ratios.

I bought jt sprockets available all over the Internet.

If you go over to the "Chaingang" web forum they sell different aftermarket sprockets, you may find a set that suits you.

As for the high RPM's at highway speeds, the Rotax is designed, and some say it likes, to run at high revs for extended periods of time. At one time Rotax advertised on its website that the engine could run 7,500 rpm's continuously between engine services.

I get 24k miles out of the OEM chain and sprockets. Very little dirt riding, some gravel, mostly paved roads and commuting. I clean with WD40 and protect from rust with with Honda chain lube every two weeks, more if I've ridden in the rain. IMHO rust, not dirt is the chief enemy of the "O" ring chain. Everyone has there own method, but as stated earlier cleaning and protecting are paramount. Regards, Jim.
