Looking for a sound frame. I think the 87 to 94 frames are the same. Cosmetics not important, going to powder coat it anyway. The peg mount on mine are a little bent and beat up.
That is a good one to get. And earlier years (pre 1990) don't have tabs on frame for mounting rear master cylinder for rear disk brake.
The frame and swingarm are beefed up a tad starting in 91 over the previous years of that generation of XR. Brakes are a touch better too.
The brake master cylinder on the front doesn't provide as much leverage as a CR master. I always put a CR front master cylinder on when I was racing them in the early and mid 90s... And after trying many different brake pads - I always ended up back with the stock nissin pads. Best feel, performance & wear. You can substitute XR650L brake pads in the front. They have more material to the inboard on the rotor - larger pad for better stopping.
In '96 redesign they started using complete CR spec brakes front and rear....
Thanks for the info! I actually have a CR front master cylinder sitting on the shelf.
I just did a test fit on the triples and forks to the new 94 frame.
The steering stops are dead on match to the XR forks.The RM forks and the XR fork tubes are 36 inches from the bottom of the axle to the top of tube.
