V-Mar products are quality trials products designed and built right here in the USA by a trials enthusiast!


100% Precision CNC machined from 7075 aircraft grade aluminum alloy, you cannot buy a better sprocket. We removed every little bit of material we could to make these sprockets as light as possible, using a unique design to maximize the strength while giving them a very distinctive look.

The key to a long lasting sprocket is the fit where each of the chain rollers fit into the teeth of the sprocket. Unlike stamped or cut sprockets, our fully CNC machined design insures a perfect fit between the chain and the sprocket, as well as the highest quality finish.

Bolt patterns avail include the 6-bolt Montesa pattern, 1997-2004 and the more common 4-bolt pattern used on the Gas Gas, Beta, Scorpa, Sherco and 2005-09 Montesa.

Sizes available in the 4 bolt pattern: 38 40 41 42 43 44 46 48 52

Replace your stock Montesa brake pedal with our beautiful machined billet pedal. The V-Mar pedal is a bit shorter than the stock unit so it is easier to reach, especially if you have moved the foot pegs farther back. The tip is hinged to deflect when you get a little too close.

These replacement rear shock linkages are designed to reposition the rear shock in order to give the rear end of the Montesa a slight lift, and slightly stiffer feel. It eliminates the rear end sag and gives the bike a more lively rear suspension. Giving you improved 'hop' without sacrificing the excellent rear end traction. CNC machined from 6061 T6 aluminum and black anodized.

Replace your stock rubber chain guide with our super tough UHMW plastic guide. UHMW is an extremely tough industrial plastic that 'lubes like oil and wears like iron.' It is very slick and very tough at the same time. We have two sizes available, the standard width to replace the stock rubber guide using the standard chain, and a wider version designed for use with an o-ring chain. As with all V-Mar products, the chain guides come complete with all new mouting hardware. $20

Reservoir Caps

Replace the stock rubber carb adapter on the Gas Gas with our nice machined aluminum adapter. The V-Mar adapter is a bit longer than stock, making it easier to install the airbox, held on with three set screw (included) and sealed with an o-ring (also included) The inner profile is a true velocity stack shape, CNC machined to guide the air into the carb.

Fits all Gas Gas trials bikes. $49.95


Our newest Snail cam is desigend specifically for the Montesa. We cut in a recess to lock in the axle, and counterbore the other snail so the axle nut will fully thread onto the axle.
Starting in '07 the GasGas uses a newly designed axle that presses onto one snail and uses a 10mm allen head bolt on the other. Just tap the original snail off of your stock axle, then tap the axle into the new V-Mar snail. We even supply a new low profile button head bolt for the other side.
All of our Snail Cams are designed to look cool, as well as give more adjustment to the rear wheel. When changing to a smaller sprocket the stock cams are often too small to allow you to take out all the slack in the chain. CNC machined from 6061 T6 aluminum and come black, red or gold anodized.



The latest from V-Mar are our rubber valve stem caps. For quick tire pressure adjustments just pull them off and push them back on. And to make sure you are not digging around in the dirt looking for your cap after you drop it, we built our caps with a retaining strap. Avail in Black, Red, Blue and Yellow. Sold in pairs $3.95
