10 miles on it all studded up in the snow and ice and I love this bike. I'm enjoying its power in its stock restricted form. Can tell it has alot more to offer in the spring when I uncork it.
I have made 3 rides with my new WR. Only rode 10 miles in stock form, then put the ecu and FMF muffler on. 1st time I tried the Aussie map. It was dull. Soft on the bottom. Next I tried the FMF, then the Sand maps. I like the FMF for woods. Not too aggressive but much better than the Aussie. Sand map hits hard right off the bottom then signs off on top.
Yesterday, I tried the MX map, and it was strong from bottom to top and just what I was looking for. It is very snappy on the bottom, much like the Sand map but rips on top! It's is a huge difference from stock. So nice to be on a new bike that doesn't 'bog'.
One of my concerns with this bike was that it would be twitchy and unstable at speed, as some have mentioned. I guess it would be if you set the sag where the magazine reviews suggest. I set my race sag at 102 mm and rode out to the sand wash (deep ravine with nothing but sand). The bike was just as stable as my '06 and far more stable and predictable than my 450 EXC.
The more I ride this new WR, the more I like it. Rode with a big group of KTM's last weekend, 18+ bikes in all. Tight, woods trails. Three new WR's at the top of the pecking order followed by a bunch of pumpkin-colored bikes.
