TX 300 Heritage

Multiple technical updates for 2025 ensure the versatile TX 300 Heritage maintains its place at the head of its class. A new, lighter frame is engineered to improve handling, especially when entering corners, without sacrificing straight-line stability. Accompanying the new chassis are revised settings to the WP suspension, which help maintain maximum comfort and traction across the roughest terrain. The compact, 300 cc 2-stroke engine retains its electronic exhaust control for instant power delivery in every gear. Inside the engine, all components are positioned to centralise rotating mass, which plays a vital role in the outstanding agility that the TX 300 is known for. Movement on the motorcycle remains unrestrictive thanks to the slightly taller and wider seat with the ergonomic bodywork and new radiator shrouds complete with distinctive, Swedish-inspired graphics.

Engine

The engine is at the pinnacle of 2-stroke performance and weighs just 23.9 kg. Expertly assembled with the latest technical innovations, the TX 300 Heritage model features electronic fuel injection (EFI) and an electronic exhaust control for lower running costs and assured reliability. Configured with no separate oil tank, pre-mixed fuel is required, which is identical to the motocross models. A proven e-start adds to the simplicity of this popular model and guarantees fast starting in all conditions.

Cylinder

With Electronic Fuel Injection (EFI) as standard on the TX 300 Heritage model, a traditional powervalve is replaced with an electronic exhaust control system. This highly innovative technology manages the opening of the lateral exhaust ports before the main exhaust ports open to deliver strong, controllable power. The upper contour of the exhaust port features a machined finish for unrivalled performance.

Crankcase

High-pressure die cast production processes allow for the crankcases to be manufactured with a thinner wall thickness to keep the overall weight to a minimum and to position the shaft arrangements perfectly for optimised mass centralisation. This clever design aids the overall balance and agility of the TX 300 Heritage machine while the symmetrical engine mounts enhance the flex characteristics of the chassis.

Crankshaft

Designed with weight reduction and performance in mind, the crankshaft inside the TX 300 engine improves throttle response and contributes to the lightweight feel of the motorcycle. The perfect balance of rotating masses is achieved by balancing the weights of the crankshaft flywheel and the rotor, and thanks to the innovative counter balancer shaft, engine vibration is kept to an absolute minimum.

Counter balancer shaft

The TX 300 Heritage model features an innovative, laterally mounted counter balancer shaft. This shaft significantly reduces engine vibration, resulting in a smoother and more comfortable ride.

DDS clutch

The damped diaphragm steel (DDS) clutch fitted to the TX 300 Heritage model is unique as a single diaphragm steel pressure plate is utilised instead of traditional coil springs. Housed inside a CNC machined steel basket, the overall clutch design contributes to the compact engine layout and features a damping system for maximum traction and durability.

In addition, the gear lever tip design provides optimised leverage and prevents dirt build-up, even in the toughest conditions. damping system for maximum traction and durability.

Frame

All Heritage models benefit from an advanced frame that is engineered with specific wall thicknesses in high stress areas for strength and a calculated level of flex. Overall, the chassis offers exceptional cornering agility, unparalleled rider feedback, energy absorption, and confidence-inspiring straight-line stability. The frame is finished with a premium white powder coating, unique to the Heritage models, with frame protectors offering superior protection, durability, and grip in any condition.

Polyamide-reinforced aluminium subframe

Made from 60% polyamide and 40% aluminium, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 1.8 kg. The lower subframe spars and frame mounts are manufactured from cast aluminium for maximum reliability. The upper section of the subframe is made from injection-moulded polyamide to enable specific flex characteristics and ensure a lightweight construction.

Handlebar flex can be customised with the handlebar clamp, which offers two mounting options – rubber-damped for less vibration, or fixed for enhanced front-end feedback. The upper triple clamp is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling.teristics and ensure a lightweight construction.
