For a stock framed XR100 to catch or even keep up with the TTR125 look foward to spending big $$$$. I tried with a highly modified XR95 with XR100 forks/swingarm and Technoflex suspension. The TTR ate it.

I will agree that a stock TTR is a slow bike and the XR100 is a close match but I think for less $$ you can get the TTR going a lot faster and handling a lot better. I gave up on the XR when the frame stretched and it was near impossible to get the engine out of the frame and the welds on the shock mount started cracking. That was after 6 months of MX. The TTR goes harder, is faster and overall was a cheaper package that is lasting much longer. Here in Australia there are some fast XR100 in stock frames but all have problems and most parents are looking at the TTR or doing CR frames. One thing though it is easy to sell a second hand XR. They are popular even raced ones.

Howdy Lawndart!

I have your solution...!!! My wife is selling her BBR XR120 - it sounds perfect for your son. You can email me or call me if you want more info.

Thanks! Randy Burress, Portland, OR rburress@pacifier.com

The XR100 is buildable, but it is much cheaper to build a TTR125. Why not call Powroll (www.powroll.com), they're the ones who have all the fastest XR100's, and the fastest TTR125's (BBR uses Powroll parts for their conversions).
