The specialty

Beta suspension, model by model

All Moto Performance specializes in Beta suspension: the Standard RR, Race Edition, Xpro and XTrainer. That means correcting the compromises in the factory valving and tuning it to your terrain and pace, getting your spring rates right for your weight in gear, and knowing which quirks belong to which model.

The bread and butter

Springs and valving, done right

The bread and butter of any setup is springs and valving. How those are utilized and implemented will determine how well the suspension works for you and your intended terrain.

That is a lot more than making it firmer or softer. A revalve corrects the shortcuts and compromises the factory made to suit a broad audience and keep production costs down. It puts the damper circuits and features the manufacturer misused to work properly. Then it tailors the result to your terrain, your bike setup, your riding style and your pace, with springs matched to your weight in gear.

Preload is worth a look too, but how much it matters depends on the model. Excessive fork spring preload is a big part of why the stock XTrainer feels the way it does. The Race Edition and Xpro are nowhere near as bad.

Model by model

Which Beta you ride changes the plan

Different forks, different strengths, different upgrade paths. Every setup, what it includes and what it costs is on the packages page.

Standard RR

2013 to 2024

On the 2019 to 2024 bikes with Sachs forks, the Lainer Conversion improves the stock architecture and is highly recommended at a minimum over a basic revalve. From there the Lucky, Raven and Blackjack cartridges replace the fork internals outright, each one valved and tailored to suit the rider.

The 2013 to 2018 bikes use a more typical open chamber fork cartridge, so the Lainer Conversion does not apply. Every cartridge is available for them at the same package prices.

Setups from, whole bike $1,245

Standard RR packages

Race Edition

2013 and newer

KYB forks from 2020 on, and the better design. Before 2020, a Sachs closed cartridge fork. Those 2019 and earlier bikes can get a basic revalve, springs and valving, but no cartridges are available for them.

In stock form it is better on faster, flowier terrain, and it is the cheaper bike to get to a great result once it is revalved. Springs, valving, the AMP Compression Adjuster and a low friction piston band get you a solid end result.

For cartridges, the Lucky is recommended for slower, more technical riding, as there are some compromises over reworking the stock internals. The Raven is head and heels better than the stock cartridges and better suited to a broad range of off road riding. The Blackjack is suited to motocross, arenacross, or high speed riding with large impacts. Every cartridge installed here is valved and tailored to suit the rider.

Setups from, whole bike $1,245

Race Edition packages

Xpro

Sachs SHC forks, 2025 and newer

In stock form it feels better than the Race Edition on tight, technical single track at slower speeds. The Blackjack is an excellent closed cartridge upgrade, replacing the stock open cartridge design that is very prone to cavitation. Because the Xpro runs a single cartridge, it makes a great all around solution for general off road and racing applications, and along with the same shock work it meets the level of a revalved Race Edition, or betters it. Like every cartridge installed here, the Blackjack is valved and tailored to suit the rider. The Lainer Conversion is not an option on these forks.

Setups from, whole bike $1,395

Xpro packages

XTrainer

Lightweight enduro, 200, 250 and 300

To hit its lower price point, Beta saved money on more budget oriented suspension. That, along with poor internal settings and excessive fork spring preload, makes it harsh, bouncy and deflective out of the box. It is no problem to fix, starting with the parts the bike already has.

For the shock, the MXT46 is machined by MXTech to AMP's specs for the XTrainer, built to suit you with the right spring, $1,800. The best shock money can buy under $2,500.

Setups from, whole bike $1,180

Beta riders, after the work

Word for word from emails riders sent Aaron once they'd put some time on the bike, and from reviews they posted on Google and Facebook. Nobody was paid or discounted for the emails.

First off it's completely amazing!!!!! Seriously changed the bike so much and I have zero desire to ride any other bikes especially my 450 in the woods... it's the best handling bike I've owned now.
Josh M. 2023 Beta XTrainer 300 · August 2026
Excellent job on the suspension. Night and day difference from stock. You can attack anything and the bike is so stable and predictable. Well done.
Mark L. Beta 300 RR · May 2024
I thought there would be an improvement, but not this drastic... it did not deflect on bumps a single bit. after riding a while I realized, the rear tire never left the ground unless I wanted to... I actually found myself riding a gear higher and faster on the same trails I normally ride.
Van G. 2024 Beta XTrainer, MXT shock · March 2026
Overall im very happy with the setup. Handles chopy trails like its not even there. My confidence on the bike is so much higher since your work.
Dustin P. 2023 Beta 200 RR · August 2026
I have over 160 hours now on the springs, front MX Lucky cartridge, and rear MXLucky shock. All of them joyous... Much thanks for totally transforming my humble XTrainer.
Hal M. Beta XTrainer · October 2026
Was absolutely blown away by how good it was. Any of the scary higher speed stuff was completely gone same for brake dive... Probably the best 900 bucks I've ever spent on a bike.
Reed H. Beta XTrainer · December 2024
The suspension felt great in the desert. VERY different than both the XCW and stock Xtrainer!... It didn't deflect, was amazing in the rocky sections and I was pleasantly surprised how well it did in the thick sandy washes!
Teresa W. Beta XTrainer · March 2026
I'm thoroughly impressed with your level of communication and sharing of information. It's a breath of fresh air.
Charles W. 2019 Beta XTrainer 300 · July 2026
To say it felt like a new bike is almost an understatement. My wife equated it to moving from a hardtail mountain bike, to her first full suspension. Instantly a better (and safer) rider, and was able to conquer ledgers and rocky climbs that she wasn't close to clearing before.
Ryan H. Beta XTrainer Google review
He took the time to get to know how I ride and my goals as I develop, and he helped me understand my options without trying to "sell" me on upgrades I don't need at my level... We ride in rocky north and central PA, and I was faster than I've ever been.
Kaci S. Beta XTrainer · December 2024 Facebook review
I sent him the forks & shock from Arizona, he followed up one more time to confirm once received. He told me 2-3 weeks to turn them around and that's exactly what happened. He told me what I could expect, how much better the bike would feel and that is exactly what happened.
Ken S. 2025 Beta XTrainer Google review
The bike can be ridden much more aggressively yet it soaks up the small stuff 100% better than stock. Another side benefit is the cornering is greatly improved. In stock form the bike just wanted to stand up in a rutted corner. Now the bike tracks quite nicely through same corners.
Robert K. 2023 Beta XTrainer, Impact shock, Lucky cartridges · April 2023 Facebook review
Transformed the suspension on my Beta 300 XTrainer. Truly a night and day difference... I was hesitant to ship my suspension, but Aaron was extremely professional communicating when he received my parts and he even gave me a call to review everything when it was my turn on the bench.
Nick A. Beta XTrainer 300 Google review
Aaron revalved my '2018 390RRS with outstanding results. Much more planted and plush. Removed deflection on rough cornering, added traction on rocky climbs, and still controlled on braking and trail jumps/whoops.
Joe S. 2018 Beta 390 RR-S · September 2020 Facebook review
Aaron was great about asking what my budget was and what options we had within that budget... Turnaround was quick, and my wife cannot be any happier with how the bike rides! She went from basically not wanting to ride, to asking when we can get out again.
Jordan C. Beta XTrainer Google review
Transformed the bike, making it far more stable in the whoops... After speaking with Aaron and discussing the type of riding we would be doing, he sorted out springs and suspension, shipped the product and it arrived in Canada in less than a week.
