I just checked out the new yamaha on there website, 350lbs, 439cc, titanium 5-valve, 11.9:1 compression ratio, 39mm fcr with tps., aluminum upper a-arms. The weight, carb and power to weight look good, but I think I will be much happier with my predator. They are crazy wanting a msrp of $6899. Looks like a good track bike, but other than that, they can keep it.
