Today, as part of my 5000km service, I had a 16 tooth front sprocket fitted.
The DL650 comes standard with a 15 tooth front sprocket, and while this delivers a high degree of power to the road, revs at the top end are rather high.

By changing to 16 teeth I have effectively wiped off 1000rpm from 6th gear. This has also had the added benefit of smoothing out 1st gear.

When I start "touring" I may put back the 15 tooth sprocket depending on where I intend going, but for general commuting and highway work I can recommend making this modification.

My fuel consumption is 23kms/litre. I have just filled up so will report back in a week or so what kind of difference an extra tooth has made.

Well I'm impressed. The extra tooth has given me, essentially, an extra gear to the top end. It has probably halved the power of first which will make any real dirt work a little challenging.
