I am currently using wertz unbreakable levers on my 2006 cr250 and my clutch feels very heavy. the bike has had a full new clutch including a new cable and the clutch is still hard to pull. when I put my brothers zeta unbreakable levers on the bike it frees up quite a bit. so, it your opinion what is the best clutch lever you can buy? i'd prefer it to be unbreakable as I do enduro and after 2 hours riding, what fatigue sets in, crashing is inevitable.
