We raced GasGas for the last 2 years and because of the loss of the distributor and rider support, we are on 08 KTM's for next year. My son has a 08 200XCW and rides AA and I have a 08 300XCW and ride open A. The 08 KTM chassis is the best handling KTM I have every rode. In the past, the bikes were light on the front and would skip off trail trash unless valved and sprung light. This made them unstable at speed and wallow in the turns. The new chassis can use stiffer front settings and still feel plush because of the added front end weight bias. Compared to the 05 up GasGas chassis, the 08 KTM feels much like the GasGas. It feels stable and predictsablelike the GasGas until there are bumps in the trail. The 08 KTM suspension is good by KTM standards but is 5 years behind the GasGas suspension. The 08 KTM fork is full of stiction compared to the coated Marzocci forks and the valving is too stiff. Revalved, the fork goes from poor to average. A revalved Marzocci fork is the best fork I have ever rode. The only problem with the GasGas fork is the oil gets dirty and needs to be changed every couple months. On the rear, both ends need a revalve but the GasGas works over a wider range. The KTM shock is very limited in what you set it up for. If you want compliance in rocks, it will wallow at speed. If you set it up for higher speeds it will dance around in the rocks. The 08 KTM now comes with an aluminum shock body which sould help the shock run cooler and not fade like the steel body shock did. The GasGas shock is always the same hot or cold. Other notables: The brakes are strong on both bikes but the GasGas has a better feel. The KTM 200 has a narrow clutch feel while the 300 clutch feels as good as the Gasser's: Wide engagement and easy to use. Quality wise, the fit and finish is better on the KTM but GasGas reliability is outstanding with none of the issues the KTM's have. We have less than 10 hours on the 08 200 and the kick starter gears already broke. We raced GasGas for two years and never had a part fail. The last time we raced KTM's was in 05 and we had several DNF's due to brake failure, clutch slaves and masters, boil overs, and the never ending quest for decent suspension.
Motor wise, the 08 200XCW is a bit of a disappointment. Good bottom and mid then goes flat on top. Compared to the Gasser 200, it falls short on top. The new 300 KTM motor is outstanding. It will walk all over a GasGas 300. It will walk all over a 07 KTM 300 too. It feels like a 300SX. Most of my effort will be to smooth the power out and make it more useable. Hope this helps and if you have any questions, fire away. Dave
