You need to be careful that you don't order a brake and a clutch lever. Skip amazon. .
Go to ebay..."adjustable scooter brake levers"
You need two "brake" levers.
Several Asian ebay sellers offer brake levers for scooters. You need the dimensions of your lever, and a careful study of the lever you're looking to buy.
Alternatively, try contacting the seller with your year and model scooter. We've purchased a few pair of these adjustable levers from Asia - with good results.
If you're not careful....you'll buy a front brake lever and a left clutch lever.
Paid as much as $120 for a set (Japanese make) and as little as $25 for Chinese.
