2010 GasGas 2504T now powered by Yamaha. It's pretty, but it looks like Husky has everyone running scared? And no I'm a Husky guy... just thought it was of interest.
GasGas use to re-badge Husqvarna motorcycles as their own around 1990-1992. I always thought that was somewhat of interest.
GasGas has been developing their own 250F motor. It's not quite ready yet, so rather than launch it prematurely they decided to use some surplus Yamaha engines. GasGas worked a deal with Yamaha to buy a limited number of engines. Tentatively, GasGas will be making approx. 500 bikes. From early reports (CycleNews recently did a report too), these bikes are really nice. The engine characteristics compliment the excellent GG handling characteristics. So you get a very reliable Yamaha engine (from a 250F standpoint) and the great handling chassis of the GG bikes. It's a win-win situation in my opinion. Note: It also gets the new frame that GG released for 2010... looks like two perimeter frames stacked on top of each other (cross section is like a double O). Cool stuff! The only downside... people will call it a Gasaha or Yamagas.
