Get some adjustable levers. They're great for adjusting in or out for thicker (winter) or thinner (warm weather) gloves. Also if you're like me and have two motorcycles with different friction zones, you can adjust the levers so that both bikes feel the same. JPR makes some levers that are good and look like Pazzo and CRG's, but they're a bit less expensive. Check their website for pricing, I think they're like $130 or so for a pair shipped to your house. Pazzo and CRG will run you $180. ASV (my favorite) run about $100 per lever, but they also have the most adjustability and, I think, look the nicest. Check out www.motomummy.com
for deals on levers, they have a variety of brands, and their shipping is very fast.
