Klr 650 sprocket change

I do more on road than offroad riding, and most off road is back roads, fire roads, and trails. After riding with my dad, on a triumph 990 and my brother on a Suzuki V storm 650 the difference in speed is obvious. I've considered upgrading my sprocket to give me a little more higher speed comfort. Does it give a noticeable difference and is it worth the money to buy a new sprocket

I upgraded to 16 tooth and the bike is much happier on the highway. Nothing is free - there's definitely a penalty when you go off-road. Let's just say you'll get more practice on the clutch.

If you use your bike for transportation you must change the gearing. I don't know the numbers at the moment but my 1994 was good tall gearing and on my 2011 I went up in the front and down in the rear to keep the stock chain and I think the 1994 was still better so if we can find out the OEM ratios I'll know what to do with mine too.
Good luck with it

If you change the front sprocket do you have to change the rear? I ask because my bike came with a 15 tooth and I just ordered a 14 tooth to go back to stock.

You need available adjuster travel of 1/2 a link per tooth. Should be ok with a one tooth change.

NO. You will be fine.

They come with a 15 tooth front/ 43 rear.

I'm running 16/42 and stock length Tsubaki roller chain.
Rpms are in the low-mid 4's on the interstate.
Lost bottom end takeoff, got it back upstairs.
I rarely use more than first and second offroad, and
yes feathering the clutch will become a skill to you

I run 42/16 on my 2011 and like it. Good street gearing, 98% concrete it' just a great work bike for me.

For the sake of accuracy, you need 1/4 of a link (5/32") adjustment room for each tooth added or subtracted on a sprocket.

Thanks for correcting my statement. Would it be because the chain makes 2 U turns to do it's job? Makes sense. Hope I didn't mess anyone up.
Thanks again
