I'm a brand new rider, and recently acquired a '97 yzf1000. I'm 6'0" so I don't think it's too big, but should I be overly worried starting out on a such a big bike? Pretty standard question here, don't want to learn any lessons the hard way on bikes.
The Thunderace is a fast and beautiful bike. It really is a bike for an advanced rider. I suggest you keep it in the garage until you have the skills to ride it.
You'll see lots of threads like yours on this forum. I'm guessing you know it is too much bike for a beginner. It has 145 horsepower. Does 0 to 60 in about 2.9 seconds and a 1/4 mile at about 10.4 @ 133 mph.
Starting out on a bike with less than 100 horsepower will be more forgiving to the typical beginner mistakes we all made. Learning to ride a smaller bike to its maximum potential will make you a better rider in the long run. Lots of guys start off with too much bike, wreck it, and give up on riding. Don't be one of those guys.
