Completely new for 2017, the TX 300 signifies the constant development and secure future of the historic 250cc 2-stroke in the Husqvarna off-road line-up. With a newly designed chassis based on the new generation 2016 FC and TC models, the TX 300 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 ability and usability of the TX for its indented purpose. Additionally, the lightweight 2-stroke engine is completely redesigned and features increased efficiency, more centralized masses as well as a substantial reduction in vibration. As a result the TX 300 now offers a refined and manageable closed course racing package.

New Engine

The 300cc 2-stroke engine has for long been the best combination of unsurpassed power and lightweight construction. The simplicity and low maintenance cost of the 2-stroke motor has made it a favorite amongst riders for generations. Although the previous TX 300 engine was known to be the most competitive in its class, development has continued to offer Husqvarna customers a new state-of-the-art 2-stroke engine. The TX 300 engine has a completely new construction featuring a new shaft arrangements for better mass centralization, a new counter balancer shaft reducing vibration, a new twin-valve controlled power valve and re-worked 6-speed semi-close gearbox.

New Cylinder

The 72mm bore cylinder features a newly developed power valve system which delivers a smooth and controlled power throughout the RPM range. This can be further customized by simply changing two springs supplied altering the power delivery for different track conditions and rider preference. The new cylinder and cylinder head incorporate a new water jacket design which guarantees better heat dissipation and increased cooling under the most extreme conditions. New cylinder head mountings secure the engine to the frame while reducing vibration, ensuring a smooth ride.

  • New cylinder, head and power valve - improved performance, power delivery and cooling.
  • New cylinder head mounts - better fixation, reduced vibration.

New Piston

The new piston has an optimized shape and fits perfectly within the new cylinder. Additionally, the diameter of the piston crown has been increased for increased stability and reliability.

  • New piston - increased stability and reliability.

New Engine Casings

The new TX 300 engine is designed with mass centralization as a key theme. As a result the lightweight, die-cast engine cases have been developed to accommodate new shaft arrangements. The clutch shaft is now 4mm higher while the crankshaft position is 19.5mm higher centralizing oscillating mass and improving ride-ability. Additionally the counter balancer shaft has been integrated in a very compact manner in order to not affect the overall design while new engine covers offer better resistance from wear created by riders boots.

  • New die cast engine cases - new shaft arrangement, improved mass centralization.
  • New engine covers - better resistance to wear.

New Counter Balancer Shaft

The new engine design has allowed for the implementation of a laterally mounted counter balancer shaft. This shaft significantly reduces vibrations resulting in a more smooth and comfortable ride with less rider fatigue.

  • New counter balancer shaft - significantly reduced vibration.

New Crankshaft

The new crankshaft features the same 72mm stroke as the previous generation but the balance has been optimized in conjunction with the new counter balancer shaft for minimum vibration. The crankshaft is placed in the perfect position to centralize mass resulting in improved agility and handling.

  • New crankshaft - optimally balanced to reduce vibration, centralize oscillating mass.

New Carburetor

The 2017 TX 300now features a 38mm flat slide Mikuni TMX carburetor replacing the previous Keihin model. This new carburetor provides a more smooth and controllable power delivery with optimal performance over the entire RPM range. Additionally, it is also very easy to tune.

  • New 38mm Mikuni carburetor - improved power delivery, optimal performance.

New Transmission

A new 6-speed semi-close ratio gearbox has been developed to compliment the off-road usage of the TX. A revised shift mechanism ensures precise and easy shifting while an innovative shift level reduces dirt build up guaranteeing easy operation in even the toughest conditions.

  • New 6-speed semi-close ratio gearbox - precise and easy shifting.
  • New gear lever - prevents dirt build up and blockage.

New Clutch

The TX 300features a DDS (damped diaphragm steel) clutch. What this means is the clutch used a diaphragm spring instead of the more common coil spring design which allows for a much lighter clutch action. This design also allows for a damping system which increases both traction and durability.

This combined with the Magura hydraulic system guarantees a light and modular clutch feeling which is almost maintenance and adjustment free.

  • DDS clutch - light action with integrated damping system, increased traction and reliability.
  • Magura hydraulic system - light and modular clutch action, almost maintenance free.

New Exhaust

The new exhaust pipe is manufactured by WP performance systems using a 3-dimensional stamping process. After the elements of the exhaust have been shaped it is robot welded to ensure the best durability.

  • New exhaust pipe - increased durability.

Off-Road Specific Equipment

A large 2.2 gallon fuel tank gives the TX 300 the extra range needed for longer loops. The 6-speed semi-close transmission is perfectly suited for tackling the toughest off-road courses. The rear wheel is an 18-inch unit with Dunlop AT 81 off-road tires front and rear. A side stand completes the off-road transformation of the TX 300.

Benefits

  • State of the art 2-stroke technology.
  • Very competitive power to weight ratio.
  • Reduced maintenance costs.
  • Hydraulic clutch.
  • Excellent handling and agility.
