I race woods, GNCC, OMA, and local harescambles. I'm 46 and after 3 yrs I fianally one a "c" class race. The great financing on yamaha has me interested and now I might actually have a chance at contingency. The KTM has almost an electric motor feel at power, smooth and almost no hit in the power band, electric start, but it is one heavy bike, without mud. If I go with the WR am I just upgrading my KTM a couple of years, or is it really a faster lighter bike. Or how about the YZ can the motor be calmed just alittle with a fly wheel weight or maybe the cam from the WR. I thank you for any input.
