I've been in the process of making mods to my KTM to support the fact that most of my riding is on the street. Here's the latest.
1. Tires - For the street, gravel, or well defined trails I ride on, I decided on going with a true 50/50 tire set. So I went with the Heidenau K-60 Scout tires. (Note there is also a 70/30 version for the rear, but I went with the 50/50 version) These tires work great, they're very versatile, and they stick to the road like glue. They are also reputed to last for 9 - 12 thousand miles. Very happy with these tires. Perfect for my application.
2. Mirrors - I went with the Touratech folding mirrors. When folded out, I now have radically better visibility of what's behind me and they are less prone to vibration than the cheesy stock mirrors. I had to glue one of the stock mirror lenses to the mirror's frame (like it was supposed to be already) in order to keep it from rattling. Not a good mirror. I highly recommend the Touratech folding mirrors.
3. Front Sprocket - Last but not least (for this post) I swapped out the 15 tooth front sprocket with a 16 tooth version. Again, since most of my riding is on street, gravel, or well-defined trails, I was willing to sacrifice a little bit of acceleration and low-end grunt to get smoother street performance and top-end. Note that the factory gear ratio is 15/45. I've now set mine at 16/45. For comparison, the Duke, which uses the same motor, runs 16/42. Don't go over 16 teeth. There isn't room for it with the factory sprocket cover. Changing front sprockets is easy, and I can always go back to the 15 tooth version in less than 30 minutes. What difference did it make? For a given level of engine output (in 6th gear) I'm now moving around ten miles an hour faster. Speed transitions as I roll on/off the throttle at highway speeds are much less abrupt, but contrary to popular opinion, I'm not seeing a significant increase in gas mileage. Perhaps I'll see a little difference after I run a couple of more tanks of gas through it, but the initial tank indicated a wash. I expected this as the reports I've seen on the Duke's mileage is virtually identical to the Enduro R.
Have fun. I hope this post is helpful to those of you who spend more time in conditions short of full-up motorcross. My configuration didn't stop me from giving a respectable chase after an albino Doe (really) across a huge grass field last Saturday. Next time I'll be giving a report on the Progressive Handlebar Damping System (Due for delivery today).
