2021 Timbersled Snow Bike Lineup

For the 2021 Timbersled snow bike lineup, the company has focused on inspiring performance.

To do so, it has improved on its successful Timbersled RIOT and ARO 3 models from last year with a premium shocks package and a lighter driveline from their race kit in their Velocity models.

Another new model, designated with an ‘S’, will feature a lower seat height and revised suspension to help newer and smaller riders gain confidence.

Here’s what’s new for the 2021 Timbersled snow bike lineup!


2021 Timbersled Snow Bike Lineup – What's New

2021 Timbersled RIOT Velocity and ARO 3 Velocity

Timbersled has kicked its premium models from 2020 up a notch with the offering of the Velocity configuration of the RIOT and ARO 3 models.

The Velocity model of both the RIOT and ARO 3 features a lightweight jackshaft, driveshaft and sprocket design that comes from the proven 120R race kit. These improvements shave 3.5 lbs of weight off each model.

The Velocity models also feature high quality Walker Evans Racing Velocity shocks. These are a premium, highly adjustable shock with better response and bottom out resistance.

2021 Timbersled ARO 129 S and RIOT S

Also new for 2021 are a few ‘S’ models, which are designed to be easier to ride. The ARO 129 S, RIOT S and RIOT S LE feature a 3” lower seat height to help inspire rider confidence. A lower center of gravity improves agility and control.

In addition, the suspension design has better efficiency, which allows smaller displacement bikes such as 250 cc dirt bikes to power the track.

A new spindle that is 2.5” shorter, combined with a revised geometry in the rear suspension, results in an increased rake angle which improves steering geometry for easier control and comfort.

2021 Timbersled ARO 129 S

Like its big brother the ARO 129, the ARO 129 S uses the same 129” Traverse track and IFP shocks. The RIOT S uses the RIOT track and has the option of IFP shocks in the base model, or Fox ZERO QS3 shocks in the RIOT S Limited Edition model.

Mountain Sledder had the opportunity to test ride both the ARO 129 S and the RIOT S last week. For a couple of fully-grown, adult male “snowmobilers” who don’t ride snow bikes often, we found the S models not only incredibly capable, but considerably easier to control and maneuver than their full-sized counterparts. We were convinced that while Timbersled is in part marketing these models to smaller riders, that they are no less capable of building confidence in larger fellas with limited experience too. While the suspension is softer with less travel, this was not a limiting factor by any means.

The high performance Timbersled RIOT and ARO 3 models have only been available since last spring and already those models are seeing some improvements. A significantly lighter rotating mass will certainly have a big performance boost in the Velocity models, even without consideration of the premium Walker Evans shocks package taken into account. The Velocity shocks which have been proven on the racecourse are now available to riders who insist on the best.

Yet Timbersled is not satisfied with answering only to the demands of skilled riders. The company is also addressing the need to help new, smaller and/or less confident riders make the transition to riding a snow bike with its new ‘S’ models. And given the growth of the sport, that seems like a clever move. The RIOT S and ARO S models will also allow dirt bike riders with 250 cc bikes to easily transition into year-round riding.
