Yamaha motor is a 5 speed
I also don't think it's a very light motor. On the Yamaha web site their 250 WR is listed at 260lbs wet (2.1 gallon tank). The list price for the Yammi is $6700 and I can't imagine what the Gasser will cost with the Yamaha motor but I'm sure it will be at least $1000 more and just how long is this gonna be produced like this? 1, 2 , 3 years??? Sorry I'll pass on this mongrel and if I want a 250 it'll be a KTM. Despite what many here want to think or believe the newer KTM 250 thumpers are really nice bikes, are very light, handle just fine and have a 6 speed tranny
You also have the option of after market 280, 290, 320 and 350 big bore kits available depending on how deep your pockets are. It will be interesting to see how this works out for Gas Gas.
