TRRS is back with seven all-new observed trials motorcycles in its One RR lineup. The four kickstart models come in 300, 280, 250, and 125 sizes, while the 125 is left out of the e-start One RRs. All seven models get the same chassis updates, with the 125 getting different motor updates due to its differing architecture. Let’s get into the fast facts for these three high-end trials bikes from Barcelona.
TRRS is the motorcycle brand, and the machines are manufactured by TRS Motorcycles. Yes, that’s a bit confusing, so it’s worth a reminder for the non-cognoscenti.
The 300, 280, and 250 gets a new injection-cast aluminum crankcase. A TRRS rep tells us that means improved low-rpm operation. Also, the clutch cover now has the sight glass on the same side as the filling hole. The cylinder head gets a temperature sensor, and the CDI has been updated to more efficiently operate the radiator fan.
TRRS worked over the 125cc powerplant. From the top-down, it gets a new cylinder head (with a temperature sensor and matching CDI), piston, and better-balanced crankshaft. TRRS says this combination pumps up the power and reduces vibrations. Additionally, the final drive now uses an 8-/45-tooth combo for lower gearing and less vulnerability to rocks. The 125 also gets the upgraded clutch and ignition covers.
The frame gets “dimensional improvements,” according to TRRS. TRRS isn’t clear on what that means, though they also claim that it “improves assembly.”
The shock linkage is more robust.
The 2021 TRS One RR lineup has an improved airbox setup. There’s a new deflector to keep water and mud out, plus better drainage should anything get in the box.
The exhaust header mounts are beefed up, with the front mount now forged.
TRRS has updated the engine mounts. According to TRRS, this makes servicing easier, reduced vibration, and cut a bit of weight.
The front disc guard is now approved for FIM competition. This makes the TRRS safer, and the disc is less likely to be damaged.
The chain guard has had its mounting improved.
A new handlebar is found on every 2021 TRS One RR.
Graphics changes include red-anodized rims, gray paint on the swingarm, and new graphics.
We don’t have US prices or availability dates for the seven flavors of 2021 TRS One RR observed trials motorcycles.

Hello everyone and welcome once again to Ultimate Motorcycling’s weekly Podcast—Motos and Friends.
My name is Arthur Coldwells.
This week’s Podcast is brought to you by Yamaha motorcycles. Discover how the YZF-R7 provides the perfect balance of rider comfort and true supersport performance by checking it out at YamahaMotorsports.com, or see it for yourself at your local dealer.
This week’s episode features Senior Editor Nic de Sena’s impressions of the beautiful new Harley-Davidson Low Rider ST that is loosely based around the original FXRT Sport Glide from the 1980s. Hailing from The Golden State, these cult-status performance machines became known as West Coast style, with sportier suspension, increased horsepower, and niceties including creature comforts such as a tidy fairing and sporty luggage.
In past episodes you might have heard us mention my best friend, Daniel Schoenewald, and in the second segment I chat with him about some of the really special machines in his 170 or so—and growing—motorcycle collection. He’s always said to me that he doesn’t consider himself the owner, merely the curator of the motorcycles for the next generation.
Yet Daniel is not just a collector, but I can attest a really skilled rider. His bikes are not trailer queens, they’re ridden, and they’re ridden pretty hard. Actually, we have had many, many memorable rides on pretty much all of the machines in the collection at one time or another.
From all of us here at Ultimate Motorcycling, we hope you enjoy this episode!
