Why not a 16 tooth on the front instead?

Gray-haired riders don’t get that way from pure luck.

I'm very much happy with the 16 also and would go 17 if there wasn't a clearance issue without Dremeling the case.

That would rock on my highway commute!

Thanks, Bender!

Cha- Ching! I'm willing to lose on the other end as necessary.
Slower takeoff, using only 1st and second offroad, etc.

If you have to do highway miles the 16 is hard to beat. I did it two years ago and still take a trail if I want to. You just need to remember your gearing when you enter that really nasty looking stretch of terrain. Keep the R's up and use the clutch as needed.

I will add that the combination of higher gear ratio and street orientated tires should be your first clue to stay on the hardtop. I have a 16 front sprocket but run with a good aggressive tread on the wheels. I tried off road riding with a pair of Michelin street tires and it was a mess, especially the front tire washing out on anything slippery.

It seems that with the higher gearing you're always going a little faster than would be ideal when riding on a single track. When you combine this with no bite from your front tire you will be down before you know what hit you.

Noobee ?
I have a stock "08" and would like to drop a tooth on the primary sprocket. Can you go 1 tooth either way from stock and not have to shorten or lengthen the chain?......

I have a 16 x 42 and the engine is about 1,000 RPMs lower than stock gearing at freeway speeds. Remember that this gearing will reduce the quickness of engine response. Nothing a 685 kit won't cure
