The TC 250 engine features the latest 2-stroke architectural advancements, aimed at centralising rotating masses and reducing vibration, while delivering the highest level of performance in its class. The simplicity and low maintenance cost of the 2-stroke motor has made it a favourite amongst motocross riders for generations.
The 66.4 mm bore cylinder features an innovative power valve system, which delivers smooth and controlled power throughout the RPM range. The exhaust port now also features a machined finished for improved port timing and performance.
The TC 250 engine is designed with mass centralisation in mind. As a result, the lightweight, die-cast engine casings are engineered to house a compact shaft arrangement, keeping oscillating mass low and centred, adding to the overall balance, agility and ride-ability.
COUNTER BALANCER SHAFT
The TC 250 features an innovative laterally mounted counter balancer shaft. This shaft significantly reduces engine vibration, resulting in a smoother and more comfortable ride.
Precision engineered for an exact balance of stiffness and torsional flex, the frame features advanced geometries aimed at delivering accurate rider feedback, handling response, energy absorption and straight-line stability. The frame is finished off in a premium blue powder coating and standard frame protectors for superior protection and durability.
CARBON FIBRE SUBFRAME
Made from 70% polyamide and 30% carbon fibre, the unique subframe features an intelligent 2-piece design delivering exceptional strength and durability at an overall weight of just over 1 kg. Specific care is taken to create the perfect rigidity for optimal handling and rider comfort.
The header pipe on the 2021 TC 250 is designed using innovative 3D modelling. The result is a perfect shape aimed at delivering the optimum performance characteristics while also being very compact ensuring sufficient clearance in tight rutted corners.
WHEELS AND TYRES
CNC-machined hubs and high-strength alloy rims by D.I.D are finished in black. They feature laser engraved logos and are fitted with DUNLOP MX33 Motocross tyres which feature a “block-within-a-block” design for progressive cornering and superior traction on a variety of terrain.
WP XACT FRONT SUSPENSION
The 48 mm split air fork features a capsulated air spring and pressurized oil chamber for progressive and consistent damping. Extended oil and air bypasses reduce pressure peaks and new 10mm shorter cartridges and outer tubes provide refined rigidity. In combination with a new midvalve damping system, the fork provides exceptional feedback and rider comfort. The setting is easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. Additionally, the air pump needed to adjust the fork’s air pressure is provided as standard.
WP XACT REAR SUSPENSION
With updated settings, the WP XACT rear shock provides advanced damping characteristics for unsurpassed traction and energy absorption. A pressure balance inside the shock ensures consistent damping, resulting in superior rider comfort and feeling.
The most progressive engineering techniques and technology complement a long list of quality componentry standard on the TC 250.
PRO TAPER HANDLEBAR
Featuring fatigue resistance at a minimal weight, the standard PRO TAPER handlebars are manufactured to exacting standards to deliver exceptional rider comfort and control.
The TC 250 features a 38 mm flat slide MIKUNI TMX carburettor, which delivers a smooth and controllable power with optimal performance over the entire RPM range.
The TC 250 features a damped diaphragm steel clutch or DDS, using a diaphragm spring instead of the more common coil spring setup. This makes for lighter clutch action and allows for a damping system that increases both traction and durability.
The new, high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation and perfect modulation in every condition. Meaning that play is constantly compensated so that the pressure point, and function of the clutch remain identical in cold or hot conditions, as well as over time. Countless hours of race focused testing have proven the high quality, Italian-made Brembo hydraulic systems exceptional reliability.
