F800GSA front sprocket

[evoarrow]

Front stock sprocket is 16T. Are any of you using a 17T?

Is the bike fine around town with a 17T

Any suggestions for a good make?

I have one on my GSA no problem. BMW have them as they are standard on the f650/700. Jjh

Yes, drops revs by about 500 for a given speed, and OK at lower speeds

Yes, i use mine through central London and it is OK

The one from the F650GS fits fine and is one tooth bigger I cant remember the number of teeth but it makes cruising at 70mph a lot more relaxing 1st gear is slightly taller but for road use no issues up to now

I will give it a go. If it works in Central London and drops the motorway revs I think I will be ok.

Many thanks for the responses.

Nice idea, But...

Now may be it's just me but when I put a 17tooth front sprocket on my '08 F8GS it did make a good bike feel that bit nicer, but - the 500 rev drop at touring speeds put the revs right at the point of maximum vibration and my hand went numb in about 25 miles. Not great when starting a two week jaunt to the further reaches of Scotland when you live in Essex. The extra vibes caused problems with my hand, wrist, elbow and shoulder and I was warned by my osteopath that I was risking permanent nerve damage
The other thing is that I was getting 58 mpg on my daily commute into central London and the extra tooth didn't change that. Now while I'm not saying you shouldn't make the change for me I don't see the point; and having been to Berlin and back in September 2014 with a bunch of mates the bike stomped down the French and German motorways at 90+ and didn't feel any busier than my old 1150GS ever did; and still gave me better mpg than both the 1100 Pan Euro & the 900 Trophy.
Sorry if that sounds negative but a nice change in one area can have a number of side effects that aren't so nice.
Bottom line, for me, is that the change caused more problems than it solved; and it wasn't enough better to make it worthwhile spending the dosh to solve them. For less than £20 I swapped back to the 16tooth pinion and all the problems went away.

Worth noting. It's not happening on mine. I've about 5,000 miles on mine since. I wonder if it's a problem on the f650/700? Maby the sprocket change highlighted another underlying problem? Jjh

 

[thomo57]

same here as Jjh, done 34,000 with 17t sprocket and no adverse effects

I will give it a few more mile before I decide. Superted has me thinking

I changed mine mainly to lower revs when on fast road work. No problems even when off road, you soon get used to it. Give it a try, it's only risking £20.

I find that my 650 is geared very tall as standard, about the same as my 1200! 650 is 17/41 and the 800 is 16/42. Have thought of going for the 16T on the front with the standard 41T on the rear. Anyone done this? Apologies for the thread hijack!

I went for the 16 tooth on my 650gs and it makes it much more tractable at low speeds in town, not noticed any loss in mpg really.

Excellent, thanks for the feedback.
