I've been out on the 990 Adventure a few times in between these crazy Spring storms and it's had a few more minor, but very important changes. First off was some suspension tuning! With the help of a buddy who works at the local KTM dealership, we broke out the factory manual and tuned the suspension for aggressive offroading, playing with the clickers adjusting pre-load, compression and rebound. The big bike probably could use a heaver set of front springs, but for now we played with what he had. It was pretty interesting to see how the suspension was adjusted as I got it, the forks were set at different compression & rebound settings!
Next up was tossing on a fresh set of rubber... I was happy with the Heidenau K60 Scout on the street and it wore like IRON, but it was pretty pathetic offroad. There were plenty of times offroad that I lacked both braking power due to the rear tire sliding around or accelerating power due to it spinning. The Heidenau is over 1/2 worn and is showing a solid center stripe of rubber, so it makes sense that the traction is lacking offfroad. I was very happy with the TKC80 on the front so I went with another of the same, it's hard to choose anything else when I got around 6,000 miles out of the last one, it does well offroad and killer on the twisties! I then decided that it was time for a real knobbie out back. A friend said that a rally bike needs a rally tire, so I bought a Dunlop 908 RR (Rally Raid!) for the rear. People are claiming that it's a great all-around knobbie and lasts 2,500+ miles on a 100 HP bike. It wasn't cheap, but the increased traction offroad will be worth it.

On Sunday I went on a ride with a friend, we rode up to Glade Park, CO and down Sheep Creek Road to Gateway, then up John Brown canyon and over the La Sal mountains and down Sand Flats road to Moab. In all, we rode 250+ miles in VERY rough terrain (getting to and down Sheep Creek is brutal on a big bike!). Then we hit the highway & freeway on the way home... the perfect ride for these big adventure bikes! I ended up dropping my bike once when my rear brake went away....
Somehow the brake pedal got forced under the engine case and overheated the brake until it quit working... I came to a steep section, tried to grab the rear brake to help slow me down and.... nothing. I got on the front as hard as I could (it was very rough & rocky) and eventually it washed out... right as I was about to run off the road and into a big boulder.
The guy I was riding with ended up dropping the BMW 4 times, once due to a sheep that clipped his front tire at 30 MPH!
I was super-impressed with the suspension tuning work, it almost feels like a different bike. Night & day difference in how planted and controlled it now feels! I managed to launch the 990 a handful of times and pulled plenty of wheelies! It flies and lands much better!
The knobbies also really helped, that Dunlop 908 rear is so much better offroad. There were a few times where I thought I was going to loose traction in rocky, rough sections only to have that tire find the grip and keep the bike moving forward. The tire does howl on the road, but it's not the loudest tire by any means. There are also a little more vibes, but I'll gladly trade those 2 things for better offroad performance.

Sheep Creek road.... it's steep, loose and has a ton of nasty switchbacks!
