The TX 300i signifies the constant development and secure future of the historic 300cc 2-stroke in the Husqvarna off-road line-up. Featuring the latest technology, the TX 300i is a purpose-built closed course racing 2-stroke with off-road specific features. A larger fuel tank, an 18-inch rear wheel and a side-stand increase the usability of the TX for its intended purpose. Additionally, the lightweight 2-stroke engine is efficienct using modern electronic fuel injection, centralizes mass and features very little vibration thanks to a counter balancer shaft. As a result the TX 300i offers a refined and manageable closed course racing package.
FRAME
The chromium molybdenum steel frame is expertly crafted using laser-cut, robot-welded, hydro-formed tubes, ensuring the highest level of precision and quality. The specifically crafted geometry utilises advanced longitudinal and torsional flex characteristics, for unparalleled rider feedback, energy absorption and exceptional straight-line stability. The frame is finished off in a premium blue powder coating with standard frame protectors for superior protection and durability. |

COMPOSITE CARBON FIBRE SUBFRAME
The carbon composite subframe is unique to Husqvarna Motorcycles and showcases advanced production technology and innovation. Using 70% polyamide and 30% carbon fibre, the 2-piece subframe has a total weight of just over 1 kg. With the help of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort. |

MAGURA BRAKING SYSTEM
The Magura braking system is designed for high sensitivity, providing a modulated feel while delivering superior stopping power. GSK wave disks (260 mm disc front and 220 mm rear) complete the high-quality braking package for complete confidence. |
|
WHEELS AND TYRES
CNC-machined hubs and high-strength alloy rims by D.I.D are finished in striking black. They feature laser engraved logos and are fitted with DUNLOP GEOMAX tyres which feature progressive cornering and superior traction on a variety of terrain. |
FUNCTIONAL BODYWORK
Clean, Swedish-inspired design and ergonomics are tailored to deliver exceptional comfort and control, enabling riders to perform at the highest level for extended periods of time. As a result of extensive testing, the slim contact points make shifting between riding positions easier and allow the rider to flow with movement. The flat seat profile, together with the seat cover texture, deliver superior comfort and control in all conditions. |
|
WP XACT FRONT FORK
The 48 mm split air fork features a capsulated air spring and pressurized oil chamber for progressive and consistent damping. Pressure peaks were reduced through extended oil and air bypasses. 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 SHOCK
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 fully adjustable component delivers 300 mm rear wheel travel, as well as unrivalled traction, feeling and energy absorption.

MAGURA HYDRAULIC CLUTCH
The reliable, high quality and German-made, MAGURA clutch system is near maintenance-free. This guarantees even wear and perfect modulation in all conditions, with constantly compensated modulation and play on the lever, so the pressure point and clutch remains consistent in cold or hot conditions as well as over time.
|
PRO TAPER HANDLEBAR
Manufactured to exacting standards, PRO TAPER handlebars feature class-leading strength and fatigue resistance with minimal weight. |
|
MAP SELECT SWITCH
By using the MAP SELECT SWITCH, the engine characteristics can be tailored to modify the power delivery according to rider preference, conditions and terrain. It has two settings which can be toggled on the fly, namely, Map 1, for standard and full power and Map 2, for softer power and delayed ignition timing for terrain with less traction.

|
DDS CLUTCH
Black high-strength alloy rims by D.I.D are coupled to CNC machined hubs using lightweight spokes and silver anodised aluminum nipples.
|
ENGINE
The TX 300i features an advanced electronic fuel injection system. This comprises of a set of fuel injectors positioned at the transfer ports which deliver the ideal amount of fuel to the engine in every condition. This not only reduces fuel consumption and emissions but also delivers a clean & smoother power delivery giving the loved 2-stroke a new edge. |
|
CYLINDER
The cylinder design includes two inlet positions located on the transfer ports at the rear of the cylinder where a pair fuel injectors are mounted. The injectors deliver fuel downwards into the transfer port guaranteeing excellent atomisation with the air travelling upward to the combustion chamber. This ensures a more efficient combustion resulting in reduced fuel consumption and emissions.
|
|
THROTTLE BODY
The TX 300i uses a 39 mm throttle body which regulates the amount of air entering the engine via a butterfly operated by dual throttle cables connected to the handlebar throttle assembly. Unlike 4-stroke throttle bodies, fuel is not introduced at this point but rather 2-stroke oil is mixed with the air entering the engine to lubricate the crankshaft, cylinder & piston. Additionally, a throttle position sensor (TPS) relays airflow data to the ECU which in turn calculates the amount of oil and fuel delivered to the engine while a bypass screw regulates the idling speed and a cold start device opens a bypass providing more air for cold starts. |
|
COUNTER BALANCER SHAFT
The TX 300i features an electronic oil pump which feeds vital 2-stroke oil into the engine . The pump is located just below the oil tank and feeds the oil via the throttle body meaning the oil is not mixed with the fuel eliminating the need for pre-mixing as on traditional 2-stroke engines. The pump is controlled by the EMS and delivers the optimal amount of oil according to the current RPM and engine load reducing waste as well as excessive smoke being transmitted from the exhaust. The oil tank is located beneath the fuel tank and is connected to a filler hose which runs through the upper tube of the frame to a filler cap conveniently located for easy refills. The tank capacity is 0.7 l and is connected to a low level sensor which illuminates notifying the rider when the tank needs refilling. |
