BRP SUB Mount - Stabilizer Under Bar Review

If you haven’t heard of BRP Racing Products this will be an excellent introduction to the quality products they produce. The BRP SUB (Stabilizer Under Bar) mount is a product that allows Scotts steering stabilizers to be mounted under the bar instead of the more traditional approach of mounting them on top of the bar. What difference does it make where the stabilizer is mounted you might ask?

QUICK FACTS

Price: SUB Mount - $129.95, SUB Mount w/Tower - $199.95, SUB Mount Scotts Kit - $499.95. Bike specific requirements may increase these prices.

Well, there are several reasons why BRP’s SUB mount is a better solution. First, mounting the stabilizer under the bar increases rider safety. With the stabilizer under the bar the rider isn’t exposed to impacting the nearly 2” thick stabilizer in a crash. Trust me, having a stabilizer implanted in your sternum with or without a chest protector is not something you hope doesn’t happen, but something you do whatever you can to avoid happening. Second, mounted under the bars means you have a shorter post which increases rigidity and improves stabilizer results. Third, if you’re a tall rider the SUB mount lifts the bars while utilizing the space under the bars. At 6’3” I run with +15mm bar risers. When you add 2” of stabilizer on top of the higher bars it really extends the “height” of the total package. If you’re not a tall pilot, you’ll do well with bars with a lower rise to compensate for the SUB Mount’s height. Lastly, the SUB Mount puts the Scotts stabilizer control dial closer to the rider for easy on-the-fly adjustments.

Installation of the SUB mount is quick and easy. This is especially true if you have already swapped out your stock 7/8” Renthals with a 1 1/8” fat bar. Fat bars are required as the SUB is only available in the 1 1/8" bar mount size. If you still have the stockers plan on swapping bars at the same time you install the BRP SUB mount. Also, if you already have a Scotts stabilizer you will likely need a shorter post. If you do need a shorter post you’ll need to install that prior to installing the BRB SUB mount.

The Podium

THE PODIUM

Excellent design, quality, and workmanship
Installation is quick and simple
Increases stock bar height for tall riders this is a ergonomic plus
Increases safety over top mounted stabilizer mounts
Reverse mounted stabilizer moves adjusters closer to the rider
Lower stabilizer mount location means shorter tower delivering increased rigidity

Once you are set with the correct bar and Scotts tower, installation is as simple as removing the stock bar clamps and installing the BRP SUB mount clamp. Do not reuse the lower stock rubber cones. BRP sends with the SUB mount new lower rubber cones that are narrower than the stock versions. These cones allow full left-to-right steering travel of the front wheel without making contact with the Scotts post. Make sure you refer to your manual for correct torque specifications.

Once the SUB mount is installed, mounting the Scotts stabilizer is very simple. It takes two bolts to mount the Scotts to the SUB mount. The stabilizer mounts in the reverse position in the SUB mount. This moves the adjuster dial to a position closer to you making on-the-fly adjustments even easier. The only downside to this set up is the stabilizer mounting bolts end up under the handlebar, which makes swapping the stabilizer from bike to bike slightly more time consuming. This is a very small price to pay for the benefits offered by the SUB mount.

As you can see we reviewed a black version of the SUB mount. BRP is moving away from offering red and silver anodized versions to standardize on their signature color black. This color against the gold of the Scotts stabilizer creates an eye popping setup. This is guaranteed to attract attention at the track or on the trail.

Conclusion

The BRP SUB Mount is an excellent solution for mounting a Scotts Stabilizer. This location provides improved rider safety, offers a shorter post for increased stabilizer control, provides a great solution for tall riders that require higher bar mounts, and mounting in the reverse position means on-the-fly adjustments are even easier. The quality and fit are exceptional. The provided rubber cones allow for full range of steering control with the Scotts post installed. If you’re considering a Scott Stabilizer, or already have one, this is a mounting system worth serious consideration.
