VERTEX

Vertex Piston Kits, Gasket Sets and Rebuild Kits

Vertex is an engine-rebuild catalog, so the fastest way in is to name the job first: a piston, a gasket set, a seal set or a full rebuild. We list about 2,260 Vertex products, with roughly 1,310 under Motorcycle, about 540 under UTV | ATV, around 330 under Snowmobile and about 75 under Personal Watercraft.

Vertex's own FAQ page says the company was established in 1953 as a workshop making spare parts for agricultural engines and pumps, and that its production takes place in Italy.

Pistons and top-end kits

Pistons, Rings & Piston Kits holds about 440 motorcycle listings, with roughly 100 more for ATVs and UTVs. Titles state the material, bore and compression ratio. About 145 say cast and about 110 say forged. Cast examples include the YZ85 cast kit, 47.44 mm and the YZ65 top end kit, 43.46 mm. Forged ones include the CRF450R/RX forged kit, 95.96 mm, 13.5:1 and the KX450 forged kit, 12.5:1. About 60 titles are "Cast Replica" kits, such as the Can-Am Maverick X3 kit. Full top-end kits, like the CRF450X kit, are listed by bore and model. Loose rings are listed too, such as the 53.00 mm ring marked for replica, race and big bore pistons.

Gaskets and seals

Gaskets, Seals & Kits is the biggest motorcycle group at about 630 listings, with about 310 more under UTV | ATV. Across the catalog, about 220 titles are complete gasket sets, about 360 are top-end gasket kits and about 250 are cover gaskets, including some 160 clutch cover gaskets such as the Honda XR500R/XR650L one. Around 80 are exhaust gasket kits, like the Yamaha FJR1300 kit. Oil seals run to about 215 listings, from the Yamaha Warrior and Raptor seal set to the Kawasaki KLX140 gasket set with oil seals.

Engine and water pump rebuild kits

About 215 listings are engine rebuild kits, filed in Engine Rebuild Kits & Components and its UTV | ATV counterpart. Dirt bike titles name the model and years, such as the YZ450F '06-'09 rebuild kit. Side-by-side kits are bigger jobs, like the Polaris XP 4 1000 complete kit, the Polaris Turbo R 4 kit and the Can-Am Maverick Turbo oversized kit. Around 125 listings are water pump rebuild kits, among them the CRF250R kit, the KTM, Husqvarna and Gas Gas SX kit and the Honda Rubicon 700 kit.

Snowmobile and watercraft

Snowmobile Engine Components has about 310 Vertex listings, mostly gasket kits and top-end sets for Ski-Doo, Arctic Cat and Polaris, such as the Ski-Doo Renegade ACE 900 top end gasket kit and the complete kit with crank seals. For watercraft there are sets like the Sea-Doo gasket kit with seals and the Speedster Pro-Formance top end gasket kit.

Matching the part

Read the Vertex part number, then the machine and year range. Pistons add a bore size, so check it against your cylinder.

Vertex questions

What is the difference between cast and forged kits? Titles say which each one is, along with the bore and compression ratio, so compare those against your engine.

Is a top end kit the same as a gasket set? They are separate listings, so check the title for which one you are buying.

Do you list Vertex parts for UTVs? Yes, under UTV | ATV, including Polaris and Can-Am rebuild kits.
