Since I have owned and raced many KTM's and now the GasGas, I think I can give an informed opinion. Here's how they stack up:
Fit and finish. Everything fits together nice and is easy to work on the KTM. The GasGas isn't bad but uses more odd sizes and zip ties to hold things together. The plastic fits and looks better on the KTM too.
Engines. The GasGas 200 motor is very strong on the bottom and then goes flat on the top. The KTM 200 hits hard in the middle. You ride the GasGas 200 by short shifting and the KTM 200 more like an MX bike. Different flavors. Pick your favorite.
The GasGas 250 motor feels similar to the 06 and newer KTM 250 motor but I would say the KTM motor runs cleaner and stronger than the GasGas motor does. Both motors have good useable bottom end with a nice mid range hit for open areas. The GasGas isn't bad but the KTM has a lower pull and revs just as high with a stronger punch in the mid range. I think the KTM has the perfect blend of power and control for racing off road.
The GasGas 300 is very smooth with little vibration. It is a ride all day and never get tired bike. It's not as good a racer as either 250 or the 200?s because it doesn't rev out as fast. It is a good bike for older racers or trail riders and that's why I ride one. I can ride all day and not get tired. The KTM 300 also makes smooth power but vibrates more. A lot more. It's also fussy about jetting unless you have the head modified to clean up the jetting. Then it runs clean but still vibrates. So in a nut shell, motor wise, either 200 is good depending on what you like, the KTM 250 motor is better than the GasGas 250 and the GasGas 300 motor is better than the KTM 300.
The stock jetting on all the bikes is too rich from the factory so plan on dialing all six of them in to get them to run right. The GasGas 250 and 300 also come with 6 speeds tranny's compared to the KTM's 5 speeds. For racing there is less gaps in the GasGas tranny's. For trail riding it doesn't make much differance.
Chasis wise, in 05 GasGas was way out ahead of KTM in handling and suspension. This was the main reason we switched to GasGas in the first place. Since 05 Ktm has narrowed the gap by first pulling in the steering head and then switching to the smaller fork cartridge in 07. These were huge improvements that improved fork action and turning ability. GasGas has also improved the chasis over this period by lowering the sub frame and switching to the Sach's shock to give the bike better action and stability in chop.
If the KTM forks had the nitrate coating the GasGas forks do they would most likely work as good. The rear linkage shock on the GasGas is very good and is not as fussy about set up as the KTM. For now the GasGas still has the better package both front a rear but the gap isn't as large as it used to be. The GasGas still works better out of the box and revalves are only needed on the GasGas if you want to adjust it for a particular situation. One other thing worth noting is the GasGas shock will not over heat and fade like the PDS will. This is only a problem if your a fast racer otherwise it is a non issue.
Brakes. The GasGas comes with Honda CR brakes front and rear and they are very good. The front is as strong as a KTM but has a better feel and doesn't get mushy like the KTM's do. The rears both work the same and both will over heat if you?re a brake dragger. The rest of the bikes are fairly equal. The seats, controls, levers, wheels and what not are both good but I would say durability goes to the GasGas as they don't seem to have the qwerky issues the KTM's do with leaky gas caps, rear brake piston failure and hydraulic clutch issues after a year of riding.
Last, we have parts availability. This is really a non-issue on either bike. The KTM parts are widely available and every high wear part on the GasGas is a direct cross over to a Japanese bike so if you need brake pads you buy them for a Honda CR250. Knock a foot pegs off or crack the front fender, get one from a Yamaha dealer for a YZ. Anything GasGas specific will be in stock at a dealer like Go Fasters or Road Track & Trail.
JEB did bring up some good points about the dealer network. GasGas in Spain went through a management change last year and the US importer was changed last year too. This made a mess of things by limiting the number of bikes that were imported and there were no dealer incentives to help move bikes so dealers stopped selling the bikes and a few closed shop. As a consumer I hope the new importer and management team can grow the brand here as competition always means better products at a lower price for us consumers. GasGas in Spain and the rest of the world is strong. It is only here in the US that things are screwed up so there is no danger of the GasGas factory closing.
JEB also had a good point about money. Racing is expensive and KTM offers contingency money and financing options where GasGas doesn't. Our GasGas dealer told us that the new importer wants to offer racer contingency and rider support for next year but I have not seen anything yet. KTM is also beating GasGas to the punch with the early release of the 2008's this year.
In my opinion, offering the 250XCW and 300XCW as electric start only is a step backwards. Racers are getting two bad choices. The twin chamber forks on the XC's are going to most likely have large cartridges used on MX bikes and even with revalves will not work as good in the woods as this years open cartridge forks. If you want the good forks for woods, you have to get a bike with the extra weight and cost of the electric start. This may give GasGas a nitch market for those that want good suspension, a 6 speed tranny and no electric start. Dave
