Engine

The new generation TX 300 engine is at the pinnacle of 2-stroke performance and weighs just 52.6 lb. Complete with the latest technical innovations for 2023, the TX 300 receives significant updates with Electronic Fuel Injection (EFI) and electronic exhaust control reducing running costs, removing the need for jetting changes, and improving reliability. The result is a tailormade power delivery for each gear and every situation. The known E-Start adds to the simplicity of this popular model and guarantees fast starting in all conditions.

Cylinder

The cylinder features a 72 mm bore and 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 improved port timing and 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 in the perfect position for optimised mass centralisation. This clever design aids the overall balance and agility of the TX 300 while redesigned, symmetrical engine mounts further improve flex characteristics.

Crankshaft

Designed with weight reduction and performance in mind, the crankshaft in 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 new rotor, and thanks to the innovative counter balancer shaft, engine vibration is kept to an absolute minimum.

Counter balancer shaft

The TX 300 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 TX 300 features a DDS (Dampened Diaphragm Steel) clutch, which includes a single-diaphragm steel pressure plate instead of traditional coil springs. It integrates a damping system for better traction and durability. The clutch basket is a single-piece CNC-machined steel component, which has been revised to accommodate the new gearbox, and continues to allow the use of thin steel liners that contribute to the compact design of the engine.

Gearbox

The 6-speed gearbox is manufactured exclusively by Pankl Racing Systems and ensures the highest level of durability and reliability. For 2023, a redesigned shift drum and shift fork improve overall leverage, which ensures significantly smoother and more precise shifting. A revised gear lever tip design prevents dirt build-up.

FRAME

The proven chromium molybdenum steel frame is refined for 2023 to reposition rotational masses inside the engine which together with a new shock mounting position, significantly improves anti-squat behaviour of the chassis. With optimised wall thickness in high-stress areas improving reliability, the frame continues to offer advanced geometries and flex characteristics aimed at providing unparalleled rider feedback, energy absorption, and exceptional straight-line stability. The frame is finished off in a premium metallic blue powder coating with redesigned standard frame protectors offering superior protection, durability, and grip in any condition. Additionally, the inclusion of forged brackets on the lower frame rails allows for easy installation of the standard skid plate.

Polyamide-reinforced aluminium subframe

Made from 60% polyamide and 40% aluminium, the new two-piece subframe for 2023 ensures exceptional strength and durability at an overall weight of just 3.9 lb. The lower subframe spars and frame mounts are manufactured from cast aluminium for significantly improved reliability. The upper section of the subframe is made from injection-moulded polyamide to enable specific flex characteristics and ensure a lightweight construction.

Triple clamps

Matching the new frame design and suspension set-up, the CNC-machined triple clamps provide precisely calculated geometry for increased stability. Customised handlebar flex can be achieved by the new 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.

WP XACT front suspension

The 48 mm split air WP XACT forks now offer improved bottoming resistance thanks to a new hydrostop, which applies a progressive damping force in the last 40 mm of travel for even greater comfort. The WP forks are designed with a capsulated, adjustable air spring and pressurized oil chamber for smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with a midvalve damping system, the forks provide precise feedback to the rider. The settings are easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. For improved durability, new fork protection rings prevent dirt intrusion. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard.

WP XACT rear suspension

An all-new design results in a 15 mm shorter rear shock, which is 100 g lighter compared to the previous generation while the rear wheel travel is set at 293 mm. Inside the shock is a Computational Fluid Dynamics (CFD) optimised main piston for improved initial comfort which provides strong hold-up in all conditions. Different sized holes in the shims allow them to open more easily which reduces the overall stress of the oil flow. Complete with low friction SKF seals and a revised linkage system, consistent damping, comfort, and traction are guaranteed with rebound and both high and low speed compression now adjustable by hand.

Swingarm

The new hollow die-cast aluminium swingarm is manufactured from a single piece of aluminium using an improved die-cast production process for optimal stiffness and a 190 g weight reduction over previous versions. In order to optimise and match the flex characteristics from the new frame, a new 22 mm rear axle is fitted. Additionally, the chain guard and chain slider have been completely redesigned for improved durability and are less prone to catching on external objects.

EFI

The introduction of Electronic Fuel Injection on the TX 300 brings many benefits. The ECU from Vitesco constantly analyses the running condition of the engine and delivers the perfect air/fuel ratio at all times through the state-of-the-art 39 mm Keihin throttle body. The exciting addition of EFI allowed our engineers to develop two different engine maps, which can easily be selected via the handlebar-mounted switch for a personalised riding experience. Additionally, an important reed valve revision improves intake tract sealing and prevents excess fuel build up in the engine on extreme up or downhill sections for clean running at all times.

E-Start

To ensure fast starting in all conditions, the TX 300 features a highly convenient electric start. The reliable system removes the need for a kickstart completely.
