TRS Motorcycles has unveiled a refreshed line-up for its 2026 ONE series trials bikes, introducing both fuel injection (INJ) models alongside improved versions of its classic carburettor machines. These updates aim to deliver better cooling, lighter parts, improved handling, and increased customization across engine and chassis components.

Models & Versions Available

The 2026 ONE series will offer riders several engine and configuration options:

• Fuel-injected versions (INJ) in 250 cc and 300 cc, available in both electric start and kick start forms
• Carbureted versions maintained in the range, enhanced with many of the new structural upgrades
• TRS continues to offer both ONE R and ONE RR models, each with updates under the 2026 refresh.
• In the UK, the 2026 ONE R is already listed by dealers, with multiple engine options including 125 cc, 250 cc, 300 cc, and both carb and (in some markets) injection versions.

Key Changes & Technical Upgrades

• New cylinder & cooling design — The INJ models boast a redesigned cylinder with optimized transfer ports, increased water passages, and a newly aligned water outlet to improve cooling and combustion efficiency.
• Chassis refinements — TRS has updated the upper and lower steering plates to reduce weight and improve feel.
• Translucent fuel tank— INJ models feature a semi-transparent tank so the fuel level is easily visible, with the fuel pump integrated internally.
• Brake & shift improvements — Rear brake caliper has been repositioned for improved control. The shift lever has been redesigned for better ergonomics and reliability.
• Suspension & frame arms — The rear suspension wishbone is now forged aluminium, with renewed strength and rigidity. Fork and shock compatibility is improved to match the updated geometry.
• Engine internals & mass distribution — New crankcase layouts help optimize weight distribution. The INJ versions use an improved water pump assembly (needle-cage-less design) for better cooling system resilience.
• Additional guards & protections — The underside guard (crankcase shield) is renewed with more impact resistance. Many models adopt the updated chassis arms and component integration across the range.

UK Offering & Dealer Listings

In the UK, dealer listings show a broad line-up of 2026 TRS ONE R models, including 80 cc, 125 cc, 250 cc, and 300 cc versions, plus higher-spec versions like the ONE RR, ONE RE, and versions using the INJ system. For example, one UK dealer lists the 2026 ONE R with updated spec: TECH forks, REIGER rear shock, R16V shock, Braktec brakes, and a newly designed swingarm.

What Riders Should Expect

The 2026 TRS updates aim to deliver more rider control, better cooling under stress, and flexibility between mechanical simplicity (carb) and modern efficiency (injection). Riders who value a crisp throttle feel, better braking finesse, and chassis balance will likely feel noticeable improvements.

For those in INJ models, the translucent tank is a subtle but useful upgrade for on-trial awareness. The modular design also suggests TRS intends to let riders pick the features they prefer, rather than forcing a single architecture.
