My wife has a 2001 TTR125 cycle, its to small for her but she wont let me replace it. So, I want to sup it up a bit.. What other then a simple Pipe can be done for this little cycle?? AND is it worth the power return?

 

The TTR125 is like the Honda 50 for adult play bikes. I believe BBR is the name of the company, and they make a boat load of stuff for it. pipes, motor mods, top clamps, etc... Once you build it a little, you will probably ride it more then anything else you own.
