Vertex 4-Stroke Piston

Vertex 4-Stroke Piston

KTM Joe - Kennewick, Washington Very disappointing design and instructions "The first piston set came with only 1 oil scraper ring instead of the required 2. The 3 piece oil scraper ring setup is next to impossible to install correctly into the cylinder. The piston looks like a thing of beauty although it does not come with the cir-clip locating hole like the OEM piston does but did come with the "tangs" in the cir-clips that requires the holes to properly seat in the cir-clip groves. This 3 piece oil scraper ring set and cir-clip setup is a royal pain. The OEM KTM piston set may cost more but in my opinion a much better option in the long run. I've always had good luck with Vertex 2 stroke pistons but this replacement set for the 350 KTM 4 stroke has been very frustrating to get installed correctly (definitely not for the amateur home mechanic). Missing parts, incorrect parts - very frustrating."

Vertex 4-Stroke Piston Kit - Stock Bore

Motoboy832 - J-Ville Ohio Great product "I have been running Vertex products for a while now and have had nothing but good things to say about their stuff. Bike feels fresh again and the added compression seems to have given it a little more bark. Awesome stuff as expected from Vertex"
