Lightweight, but unflinchingly stiff and supremely durable, the Bartlett is in a class of its own. The 170-190mm travel Bartlett is perfect for the new breed of ultra-long-travel bikes that are bridging the gap between all-mountain and downhill, as well as the latest ultra-capable eMTBs that are taking riders to burly, uncharted terrain. The dual-crown design provides space efficiency over a single-crown (allowing for longer travel at shorter axle-to-crown lengths), as well as stiffness and steering precision that’s unmatched.

EssenTTial Damper

EssenTTial gives you consistent and controlled damping. The damper features twin-tube architecture and a low-friction, low-pressure floating piston design for long-lasting performance. The damper has been tuned for a firm, supportive ride and external adjustability gives you broad control of low-speed compression, tunable from open to locked-out

FullFill With Ramp Control

The FullFill air-spring features independent positive and negative air chambers, providing more tuning opportunities than self-equalizing systems. Ramp Control technology gives riders powerful, speed-sensitive, and on-the-fly control of end-stroke ramp-up via a 16-position knob. Huck Puck volume spacers can be added or removed to tune baseline spring progression.

Automatic Casting Vent

Pressure relief valves are great for expelling pressure build up in your lower casting that comes from temperature and elevation changes, but they have one problem: you must remember you activate them. With our new ACV (Automatic Casting Vent) technology, that’s no longer the case. These vents are set from the factory to blow-off when pressure levels rise enough to influence your effective spring rate, keeping your ride consistent regardless of environmental factors. Two ACV vents are found on our highest-end air-sprung forks with the EssenTTial damper, while only one is needed on forks with the Lift Damper. With the Lift Damper taking up less leg volume than the EssenTTial Damper, pressure never builds in the damper leg of Lift-equipped forks to necessitate venting.

Great upgrade

I thought I'd give this a try as after I'd installed a Vorsprung Luftkappe to my Fox 38 the fork became a little bit too progressive.
I'm still experimenting with pressures but I've noticed a big improvement so far and I'd definitely recommend the noken if you've had similar issues
Great service from MRP, super quick shipping to the UK.
All good, thank you.

Handy on the fly adjustment

Replaced 3 tokens with this V2 ramp control unit. Already have the V2 damper installed. 91kg and 92 psi in the 2024 fox 38. Using around 12 or so clicks from 0 tokens and the ride is really active and linear to the middle of the stroke and ramps up for the remainder. Can adjust the bottom out with the ramp control adjuster which is right handy to dial in exactly how you want the fork to feel. With both installed I have savage grip and won't bottom out the fork.

Works well

I can see a little improvement from the V1, also seems closer to ideal damping rates according to the weight-chart compared to V1. All in all it works well and better than any major-mfr OEM damper.

Lift V.1 - great improvement for RS Lyrik

Got a Lift V.1 last fall when they were on sale. Installed about a month ago, now have ridden it 3x. Went into a Lyrik Select+ that sits on a Chromag Wideangle, running 150mm travel.

The Lyrik was my first RS fork in about 15 yrs, and I liked it pretty well as it was. But the damper seemed spikey on repeat hits, washboard, constant rockiness. And I'm usually in the "too light weight for factory damping" category.

After some good guidance from the guys at MRP I chose Yellow tune. I weigh about 150lbs ready to ride, water/snacks etc. I ride northern Rockies, so it is generally rocky, rutty, rooty where it isn't hardpack. Sometimes steep.

I set it up with the recommended amounts of compression and rebound damping, and left the same 70psi I'd been running with the factory RS damper.

After one ride I dropped air spring to 67psi and lightened each of the compression and rebound settings by one click.

It's now a fantastic fork that stays up in its travel, absorbs trail features big or small whether I'm going slow or fast. Never feels spikey or wallowy. Thanks MRP, made my fork a real crusher.

It works with the Yamaha Moro 07

Solid product, it works with the YDX-Moro 07 e-bike with some adjustments. Better than the one that came with the bike. I still have to test it on the trail.
