The piston is great, but those clips really suck unless u have that wrist pin clip tool. I highly advise you to buy one.
Great product and great price
I have used vertex for years and am always very pleased with quality and compatibility.
Always fits without having to modify ring gap or mess with anything.
Very pleased , just as good as oem ktm parts.
Awesome kit. Power for days
Great Piston for all levels of riders and racers! Easy to install and peforms better than OEM!
...this wasn't my first Vertex piston kit nor will it be my last. High quality replacement piston that has given excellent service through the years. Husqvarna had been using them for years as OEM install and that's all the more reason to use them.
I immediately noticed huge power gains all the way from low end to top end. I have never had so much power on my 1998 Honda CR250 since I bought it. I am still at stock bore, too. Installation was a breeze. Rings fit perfectly. The piston clearance was spot on. I can hardly keep the front wheel on the ground now.
quality, presentation and durability,
Although this says stock bore (2007 KTM125SX) keep in mind this is a B piston Vertex part #23928B so if you just got you cylinder replated, this is the wrong size, you need an "A" . No problem returning it, great customer service on the return but bad customer service when asked if this was an "A" piston and was told yes. Delayed my rebuild.
The quality is second to none, the power certainly noticeable...and on top of that the piston itself looks pretty cool too, excellent machine work. I would definitely recommend this piston to all my friends.
This is a great overall piston brought the power back for my ktm good tight fit
It installs pretty straight forward and if you have basic skills in engine work you will have no trouble.
i now have2 of these vertex pistons on my full moded rm85 race bike and hope to get another for my newly brought rm 125!
awesome light weight design,
good friction coating
single ring performance
good lubricating mod holes
very good price for the deal you get
The new ring and piston put the snap back in the bike so much had to let the little guy get use to the bike again. I could have got away with just rings but for the price might as well do the job right and not have to worry about it. The piston fit just like the guys said it would. Thanks
Great piston and great price.
This is a great piston. Just be sure to measure your cylinder BEFORE you buy a certain size to prevent fitment issues.
I noticed a huge power gain when I installed this piston the only issue I have with it is the C clips. They are very hard to install.
I think that your products are awesome and y'all make every thing easy! I definitely will recommend Motosport to a friend or family member! Thanks Motosport....Robert

Be sure to ALWAYS measure the cylinder bore before ordering a piston for your bike and refer to an OEM service manual for the proper specs required.
