Triumph Motorcycles' MX1 class Motocross platform has debuted with the TF450-RC Edition.
Triumph Motorcycles has announced its first 450cc Motocross bike - the TF 450-RC Edition. With RC standing for Ricky Carmichael - the man widely regarded as the GOAT when it comes to MX and the man helping Triumph enter the world of dedicated dirt bikes - the TF 450-RC Edition promises to be something special.
Highlights include a 108.5kg weight, a 450cc SOHC engine producing the best power-to-weight ratio in its class and a host of premium components selected by Carmichael himself.
Triumph entered the dirt market with the TF 250-X last year in select markets around the world and astonished many with its strong results in both the AMA racing series and MXGP in the 2024 season. If those results are anything to go by the TF 450-RC Edition is going to be one heck of a hot property when it hits the dirt.
At the time of writing Triumph Motorcycles New Zealand is yet to confirm pricing and expected arrival for the TF 450-RC Edition.

adding a personalised flair that reflects the spirit of this motocross legend. This design is
carried across number boards, swingarm decals, and other visual elements, reinforcing the
bike's unique identity.
Triumph’s Chief Product Officer Steve Sargent said: “At the end of 2023, Triumph revealed
the long-awaited TF 250-X – the first in an all-new range of off-road motorcycles. We now
have a brand new 450cc competition motocross powertrain, which Ricky Carmichael, who is
without doubt the very best in the business, has worked with us to develop. The TF 450-RC
Edition offers a balance of power, precision and durability that sets a new standard in this

POWER DELIVERY
The TF 450-RC’s single-cylinder, SOHC 450cc engine is built for racing, delivering robust
power while minimizing weight giving a power-to-weight ratio that leads the class.
At the core of this engine are top-tier components, including a Konig-forged aluminium
piston, which provides strength and durability at high speeds, and DelWest titanium valves
for improved airflow and faster actuation. The TF 450-RC’s 5-speed gearbox, with a
quickshifter fitted as standard for clutchless upshifts from 2nd to 5th gear, ensures seamless
power delivery for maximum focus on the track.
The 450cc engine's combustion chamber is fully machined for optimal airflow and efficiency.
The 3-axis machined combustion chamber and ports ensure precise geometry for peak
performance, while diamond-like carbon (DLC) coated rockers reduce friction, improving the
engine's efficiency and longevity.
The TF 450-RC’s 450 airbox and intake system ensures that the engine gets a consistent,
high volume of air, which is critical for performance and efficiency. The intake system is
paired with an air filter by TwinAir, known for its durability and filtration efficiency. The tool-
free filter access makes it easy to maintain the bike in rugged conditions, ensuring optimal
airflow at all times.
The TF 450-RC is equipped with a cutting-edge engine management and intake/exhaust
system designed to deliver exceptional performance and control. At its core, the bike
features a Dellorto throttle body integrated with an Athena engine management system,
ensuring precise fuel delivery and throttle response. This system allows riders to fine-tune
parameters like traction control and launch control via the MX Tune Pro smartphone app,
offering adaptable performance for varying track conditions.
The TF 450-RC features selectable engine maps, including a unique map customized by
Ricky Carmichael to deliver the exact power and control he demands.
BUILT TO WIN
With its narrow profile, the 450cc engine has improved ergonomics that allow riders more
control and comfort. It is housed in light magnesium covers for further weight reduction. The
high-capacity clutch features a steel basket and plates designed to handle the demands of
racing, ensuring durability during intense use. The hydraulic clutch actuation, with Brembo
master and slave cylinders, ensures smooth and consistent clutch control.
Precision, control and durability are at the forefront of the TF 450-RC’s design, especially
with the inclusion of the ODI RC4 Signature handlebars. Made from triple-butted, tapered
wall tubing, these bars are designed to deliver a perfect balance of strength and flex.
Constructed from seamless 2014-T6 alloy and hard-anodized for enhanced durability, the
bars feature oversized clamps and half-waffle ODI lock-on grips, ensuring excellent rider
comfort, vibration dampening, and impact resistance.
The top engine mounts on the TF 450-RC were hand-picked by Ricky to enhance handling,
especially under heavy front-end loads. This setup ensures the bike maintains optimal
control and stability during even the most demanding rides.
The XTrig Holeshot Device gives riders the perfect start by preloading the front suspension,
lowering the centre of gravity and reducing front wheel lift for quicker acceleration. The bike
is also equipped as standard with a Triumph Racing Hinson clutch cover, a front disc guard
to deflect debris and impacts, and a gripper seat cover to reduce slipping and enhance rider
control. These premium components elevate the TF 450-RC’s overall performance and
reliability.
EXHAUST SYSTEM
The exhaust system of the TF 450-RC is designed to complement its high-performance
engine. The standard model features a lightweight stainless-steel exhaust with an integrated
resonator to improve cylinder evacuation, and hydroformed components for optimised
routing and high gas flow.
For riders looking for an even higher level of performance, an Akrapovič titanium exhaust is
available as an accessory, with a dedicated engine map to optimize the engine's output. This system ensures that exhaust gases are efficiently expelled, minimizing backpressure and
enhancing engine performance, particularly at high RPMs.
ADVANCED ALUMINIUM CHASSIS
The TF 450-RC features a unique aluminium chassis, designed to provide a perfect balance
of performance, mass and flexibility. The frame’s spine and twin cradle design offer
exceptional strength while minimizing weight, contributing to the bike’s overall agility and
handling on the track. Hand TIG-welded craftsmanship ensures durability and precision in
every detail.
The chassis has been race-optimized for longitudinal, lateral, and torsional stiffness,
ensuring the best performance under extreme conditions. This allows for exceptional
handling and provides the rider with precise feedback and control during intense riding. The
result is a chassis that delivers top-tier performance and reliability, tailored for competitive
racing.
The light and nimble aluminium chassis of the TF 450-RC plays a crucial role in achieving its
class-leading power-to-weight ratio. By minimizing the overall weight of the bike, the chassis
allows the powerful 450cc engine to deliver exceptional acceleration and performance. This
combination of a high-performance engine and a lightweight frame gives riders unmatched
agility, control, and speed, making the TF 450-RC a top contender in its class.
Key design elements, including new upper and lower aluminium triple clamps, and dedicated
top end mounts, are engineered to handle the increased power and loads. This optimized
stiffness provides superior stability and responsiveness, giving riders the confidence to push
the bike to its limits.
The KYB AOS coil suspension on the TF 450-RC is designed for superior shock absorption
and handling. Featuring an Air-Oil Separation (AOS) system, this suspension ensures
smoother, more consistent damping by preventing oil aeration, which results in more precise
control and stability across various terrains. Paired with this is the three-way piggyback
shock, which allows for fine-tuning of compression, rebound, and preload settings. This
ensures that the suspension can be fully customized to the rider’s preferences and track
conditions, providing enhanced handling, traction, and comfort, especially during high-speed
and demanding motocross events.
CONFIDENCE AND CONTROL
The TF 450-RC features premium braking components for maximum control. Brembo
calipers and levers provide precise, responsive braking, while Galfer discs offer durability
and excellent heat dissipation. This combination ensures smooth, reliable braking
performance, even under heavy use, giving riders confidence and control in all racing
conditions.
The TF 450-RC features D.I.D DirtStar rims, providing excellent impact resistance and
stability in tough motocross conditions. Paired with Dunlop Geomax MX34 tyres, which offer
superior traction and control, this setup ensures optimal grip and performance across
various surfaces. With Progressive Cornering Block Technology (PCBT) and advanced mud
evacuation, these tyres provide a consistent performance even in challenging conditions.
Together, the wheels, tyres and technology deliver exceptional handling, stability, and control
on any track.
EXTRA EQUIPMENT AND ACCESSORIES
The TF 450-RC is built for durability and performance, ensuring riders can keep racing with
minimal downtime. With premium components, Triumph’s renowned quality, and world-class
support, the bike is designed to be reliable in the toughest conditions. A new network of
specialist dealers and a 24/7 parts supply system provide quick access to servicing and
parts, keeping riders on the track with minimal interruptions.
Riders can also use the 24/7 parts supply system to add specialist equipment and
accessories to their TF 450-RC Edition, ranging from an Akrapovič titanium exhaust with
dedicated engine map, to WiFi module kit, and from air filter covers to a Gripper seat.
