Now let me move on to the piston. I love the quality of the product. It looks really well built but I have not taken my bike for a ride yet. It is too hot here in California, where we can ride. In 2 months or so then I can tell if it holds up to it name.
the whole top end only took a few hours and was up and running. Thing sounds great and the powerband is awesome!! I haven't had it in for long so the durability has yet to be determined but so far so good.
Put a fresh top end on my sons kx100. Stock bore. Real easy to install. He felt the difference in power immediately. Front wheel easily comes up with no clutch pop. Highly recommended.
Best way to go if you prefer to run a forged piston in your 2 stroke. Great fit, finish and quality.
I've used Wiseco products for over 30 years with excellent quality. Motosport was able to get me the products quick to enable me to get roosting quicker.
Great product and quality. Fast service thank you Motorsports.
Put one in my kids yz85. With polishing the exhaust port
and roughing up intake ports.and tunnel,it made a big
difference on bottom end power.
Best bang for your buck! everything included in what is needed!
installed this on my 2001 cr125 and it has a ton more power. easy to install. just make sure to let the bike warm up. or idle around before you go ripping!
Just installed the Wiseco standard bore piston kit in my 2004 RM125. It was fairly easy to install, and the quality of the product is evident as soon as you take it out of the box. My bike is back to its old snappy, revy self again! Thanks Wiseco, and thanks MotoSport!
I just installed this piston in my 04 CR250. It is alive and fast as ever. Everything went together well and was easy to install. The only complaint is you get a little piston slap every once and a while, but that is it. The bike is fast and runs great. As always customer service at motosport.com is awesome.
Awesome shipping time, Awesome performace I have used wiseco many times and i've never been dissapointed....Motosport is by far the best online store to use
Great product awesome piston and my daughter loved the lined bag it came in
Great product . Fit like it's supposed to.
long lasting piston never had a problem running them ive had 3 every one has been fine strongest piston you can buy just let your bike warm up properly or you may have troubles because this piston expands with heat. all in all wiseco is all ill ever trust with my race bike (below) !
this is such a high quality piston, it came in its own little drawstring bag, with everything it needed except a needle bearing. fits great on my cr125. thanks motosport!!! any questions let me know.
I put this in my bike and rode it for 3 seasons. I then sold the bike to a friend and he still hasn't touched the top end. (we don't race) but the bike is still running strong. Great product
Pretty easy to install and so far good compression.
Installed this in my 200EXC when I did a complete rebuild last summer. It ran great, had great power, 215psi compression from installation until I pulled it out last week with 90 hours on it. It did me well for almost 3000 miles of singletrack, desert blasting, a trip to Moab, etc. My only complaint is that the forged Wisecos do run much noisier compared to a cast piston because of the increased cylinder-to-piston clearance required. Excessive piston slap can be heard both when the engine is cold and at operating temp. I put in a cast piston this go-round and will from here on out.
