      Great Product!
      Lindsay K. on 06/29/2009
      Pros: Great assistance for those of us who trail ride a high tourqe race bike. Eliminates stalls through even the most technical of sections. Lets you go slower when you need while retaining stock gearing.
      Cons: Little pricey. I think rekluse could move a lot more units if they could knock the price down.
      A must have!
      Gary H. on 03/22/2010
      Pros: I installed the Zstart Pro on my 09 Kawasaki KX450F. This is probably the best modification I have ever made to any off road bike I have owned.(owned about 20 different bikes over the years) Installation was easy with good instructions provided.Raced a hare scramble this weekend with the Zstart Pro clutch installed and went down 2 times in the mud. Bike stayed running and I picked it up and kept going, not to mention no arm cramps from using the stock clutch. I will get another one for my KX250 2 stroke.You have to try this. You won't beleive how good it is. AAAAA+++++.
      Cons: None
      best part for kx250f!!
      Ville V. on 11/21/2010
