I am trying to find a bike for my wife. She is only 4'11" tall, so I need something with a very low seat height like a TTR (hopefully it is low enough, havn't had her sit on it yet). But I want her to be able to keep up with the rest of us when riding, and be able to do very big hill climbs and such. I don't mind spending $1,000 to $2,000 on modifications for her, I am just trying to find a bike with a small frame to start with and the electric start is a big plus also. I thought the TTR would be the best one out of the available 125s. Can I get enough power out of the TTR to satisfy an adult? I think I have read about putting a big bore kit (150cc I think), new carb, exhaust, and suspension. Any other way to get power out of this bike?
