Hi NSR,
That's a great looking bike, and I'm green with envy. I nearly bought a slightly earlier SWM in Queensland a few years ago, but ended up passing it up and have regretted it ever since. I have been racing a Can-Am 175 off and on for a while, and the 175 Rotax is a great engine. The SWM looks more trick in the chassis and is probably a better bike. Do you plan to race it in VMX ? It does look to be a bit too original to cut up to make a race bike out of. But the 175 performs surprisingly well even in amongst 250s- at least in the pre-75 and pre78 classes- EVO might be a bit different. Is the engine very tractable, or pretty peaky ? I had a ride on Grant's 250GS a couple of years ago and was surprised by how different it was to the 250 Can-Am MX6 which is mellow in comparison.
Anyway, again- a great bike.
Cheers,
Martin
