I've had this together for a couple of years now. So glad I didn't listen to all the horror stories about these. 87 TRX250r with a 86 CR500 engine.

What did you do to take care of the vibrations from the 500cc Monster ?

I think that is the key to all these 500cc Trx conversions.

Well I'm not sure, I've never ridden one before I built this one so I don't know how it compares to other builds. What I did do was a lot of research before I began the build. The route I choose was to tie the top and bottom rails together with square tube, all the motor mounts are kept as tight as possible to the motor. I did not use any of the original 250r mounts other than the head stay which I modified to the cr500 engine. But It still vibrates. It's nowhere near as bad as all the stories I've heard and it's certainly not something you can only ride for a short time. This is what I ride 80% of the time I go to the dunes, I have a 88 TRX250r a 87 Quadzilla which are both exceptional bikes but this is my favorite.

Yep. Early on I was chasing cracks mainly the sub frame which I used gussets on. But the biggest challenge has been the rear grab bar. Aluminum does not work. I made one out of steel and so far so good.

Nahhh....You did it right....Banshee motor in a YFZ needed to be done!!!

I just hope that PANTHERA makes the motor mounts the same as the TRX250R mounts so that it will bolt right up to everyone's 250R based Quad.....and NOT force them to buy a 450R frame.

Time will tell which way they go.....it would be great if they utilized 450R parts so they're easy to obtain....but the goal should be to be for a 250R based Chassis....and truly make it the 250R's BIG BROTHER!

:D

I just saw this on Facebook this morning. I will be looking into this.  I would be more interested in this if, like you said , it bolts into the 250r frame. That would be the ultimate.

You have some beautiful riding out there, that Pilot in your other video is fueling my temptation for one.

The one I built would vibrate the rear grab bar and break it of with in an hours ride , it takes some serious vibration to do that .
