Should I buy a ZRX? Help!

i don't think you should buy it.
why would you want a sexy bike with a ton of hp anyway?
$ 4,000 is less then i have into the motor, swingarm and carbs for my project.
which is less than what you would put into a rex motor to rebuild it if it has been abused.

Take your time and use your gut instincts. There will always be people around hard up for cash and need to sell their bike because they have too many toys. You might have found the right bike and just need to talk to the guy and get him down a bit.
My brother bought a 1000 gsxr with 2k miles only for 6k when they were over 10k new and with a carbon pipe. The bike was only 2 years old. He sold it 2 years later for a good deal more than what he paid for it as he did all the bikes he ever owned. Someone is always motivated to sell you just gotta find em and read em. I know I would ask a good deal more than what I expect to sell for as does everyone else. The guy might be the same way or not all depends.
I rode that bike like I ride my kz and found out the real reason why I don't ride those bikes: 1. I value the ability to have kids some day. Getting killed on it less than actually abusing my future children to the point of not wanting to ever be born. 2. I don't want to lose the use of my hands due to messed up wrists. 3. I was doing 88 miles an hour looking up at the stars one night IN FIRST GEAR AND STILL HAD 2k rpms to go to redline. Jail time entered my head. The whole week I rode his bike I could never keep the front wheel down on the ground. What is the point of going 188 miles an hour besides being scary the road becomes much more difficult to manage and the probability of death goes way up. I don't want to die and I don't want to stop riding hard so I stay with bikes that make sense. The ZRX is a bike in between slow and stupid fast and is comfortable enough and fast but not too fast. I think, perhaps, it may be a great bike to ride.
