Customer Reviews
I put this top end on, started first crank, I rode the heck out of it the first ride. Runs great. Literally can’t beat the price . If it blows up in 6 months I would still be happy , an order another kit
Solid top end honestly. Gap the rings properly and you will have no issues. For the money it’s fine.
got it in today, expecting somthing to be broken or missing but nope, came well packaged and with all parts as described, comparing it to the oem cylinder and other parts can hardly tell the difference, just the head is different color
This kit is definitely a game changer, improving performance and reliability. Everything in this kit fits my bike perfectly. Installation is simple and requires no additional modifications. I am very satisfied with this shopping.
Didn't get an order confirmation email and took a while to get item so actually thought it was a scam but did receive the item and got communication email after asking about delivery of item.
78mm Cylinder Big Bore Kit For Kawasaki KLX 250 KLX250 S KLX 250R 250SF 93-14
Fast & reliable, I had the parts in Three days!
Installed four-ish months ago and rode all summer with zero issues. Seem to be good quality and the cost is much cheaper than OEM parts.
