Basically I snapped the stock levers off my blaster and needed a quick cheap set right away. Motosport got them to me fast and they installed perfectly, no modification at all. I have since put them to the test and they are iron clad. Now with a better fit for my hand and the durability I also feel I am putting less stress on my clutch/brake cables. The rubber grips have been great too! These are great for anyone that isn't into high dollar race equipment and want to save money, besides with the money I saved I was able to buy a jersey and still save money.
