The TL-250 often gets panned as a trials bike, but I had nothing but good experiences with mine through 15 years of vintage and twin shock trials events, and pulled off some decent finishes with it. The bike is a bit low and heavy...and being a larger rider helps here! Newer TLR shocks helped get the cases up off the ground (and quickened the steering) but when you get past the weight, the motor remains the saving grace, making nice power over a great range, lots of revs, minimal revs... take your pick, and with an incredible ability to find traction.
Even better is the reliability... with 15 years of adding gas, occasional oil changes and a few wear items being the entire effort. That's performance in my books!
