Handling torque and power transmission as well as suspension cinematic, the swingarm is key to a motorbike.

Whether you’re a dirt jumper, an enduro addict, a Supermoto warrior or an MX ninja, the factory Sur Ron swingarm – designed for stock power and rolling parts – is too fragile and has too much flex for serious riding.

Most of the higher powered bikes end up with a cracked or broken swingarm. In fact, it wasn’t meant to handle the huge torque delivered by the power-upgraded bikes. This is why we developed our own Sur Ron Swingarm.

Entirely CNC made from aviation-grade 6061-T6 Aluminium, the Sur Ron Racing Swingarm improves robustness & rigidity for better terrain feedback and higher resistance to hits and torque. Long story short, our Swingarm brings the MX look and strength to your Sur Ron.

Featuring a slightly longer wheelbase than the stock arm, the Racing Swingarm allows for an improved stability without compromising the bike’s agility. It has an added 20 mm total length and only requires a two chain-link addition at the shorter wheel position.

In addition to that, working with prime quality 6061 Aluminium combined with the 5-axis CNC machining process, allows us to deliver a swingarm that’s almost the same weight as the original. At 2,5kg on the scale, it’s merely 500g heavier than the factory version.

Rider’s questions

1 - 10 of 12 questions

I saw a question asked about a chain guide, and I wanted to express my interested for it as well. There is not many chain guide solutions for LBX and riding hard enduro I have lost the chain many times in rock gardens. Would be an amazing addition, as I plan to buy this swing arm this spring. Has there been more talk of implementing a chain guide? 0 answers


How much more chain slap are you getting. Because the Apollo RFN has a very similar swing arm and it leads to a very flexible ride in the back like your always riding on a flat back tire and makes a bunch of clickidie clackadie sounds down the trail. All due to the longer swing arm and chain slapping. 1 answer

The chain doesn't get more slap than with the stock swingarm. Properly tensioned it doesn't get much play and stays at bay while riding.

Does the swing arm have an attachment for a chain guide for the sprocket on the rear wheel? Unfortunately there is no swing arm like this on the market and it makes sense especially for enduro riding 1 answer

It doesn't have it as of yet but it is something we're considering for the future.

What max rear wheel size ist mountable ? 1 answer


Quentin mto logo

Hey Lars, if you're asking about tyre width, no real change from the stock swingarm as large tyres are rubbing against the chain (and we cannot change its position).

Does it come with mounts to fit the stock mudguard? 1 answer

Not currently. We're working on something though!

This swingarm is a game changer.. Excellent quality, robust feel when using a heavier rear wheel. Good price/quality ratio compared to other manufacturers!

Solid, simple, fits perfect.

The title says it all. I received my swing arm from France in a couple weeks. Went in without any problems. Feels amazing.
