Theses levers are great for riders with smaller hands. Red Plate Powersports had the best service and pricing on these levers.

ASV lever

Excellent service and reached out to make sure I got what I needed. Got the lever in under a week here in Kentucky. Actually ordered another for another bike because of service.

Awesome product

I was really hoping for this lever to help my 4 year old on his stacyc and it made a huge difference. Closer to the bars, easier for him to squeeze as he is 4 and all around great lever. Super happy with the purchase.
