1. Definitely worth doing for your TTR125
I always thought that the front brakes were really weak on my son's TTR125. I had great experiences with Spiegler's lines on my Kawasaki Z900 so I decided to give this product a try.
Definitely do this upgrade on your TTR! It provides greater stopping power and much better feel than the stock lines. And by choosing colors, it adds something special to the appearance of the bike.
