I have wanting to do this project for about a year and finally got a 2003 TTR 225 rear brake lever. The stock TW lever is 4 1/2"long and 3 1/8" from center of the brake mounting stud or what is called the break camshaft to the center of the break rod. The TTR 225 is 5 3/4" long and 4 1/2" break camshaft to the center of the break rod. All that to say with this change I have 1 3/8" more leverage applied to the breaks than before. With the Terra Cross 26-9-14 and me 255# and what I carry I had to really apply foot pressure to slow and stop all that weight. Now with the new TTR break lever the amount of foot pressure is minimal. FEEL LIKE A DISK BREAK TO ME! There is some work to this. The TTR lever is a little thicker at the break camshaft and some filing of the splines to mount the lever position further to the rear of the bike due to curved TTR lever. Very happy with this.
