TC 150 HERITAGE

01. Faster and wiser

Engine

The new TC 125 engine sets the standard for performance in the highly competitive 125cc class and weighs in at just 39.4 lb. The lightweight engine features the latest innovations to produce more torque while retaining its high-revving 2-stroke character. These revisions ensure both beginners and seasoned professionals can ride faster on the race track while further centralisation of rotating mass inside the engine significantly benefits the overall handling of the TC 125.

Cylinder

The cylinder features a 58 mm bore and as the TC 150 Heritage model is fuelled via electronic fuel injection (EFI), the traditional powervalve is replaced with an innovative electronic exhaust control system. Using an actuator, the lateral exhaust port and main exhaust port open simultaneously for maximum power delivery.

Crankshaft

The lightweight crankshaft leads to a more instant throttle response and keeps vibration to a minimum. The component is precisely positioned to ensure rotational mass has very little effect on the overall handling of the motorcycle.

Crankcases

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 optimise mass centralisation. Symmetrical engine mounts aid handling by contributing to the flex characteristics of the chassis. Internally, all engine components are positioned to achieve an ideal centre of gravity.

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.

DS Clutch

The diaphragm steel (DS) clutch fitted to the TC 150 Heritage model features a unique design where a single diaphragm steel pressure plate is used instead of traditional coil springs. Housed inside a CNC machined steel basket, the overall clutch design is highly durable and contributes to the compact layout of the engine.

Chromium molybdenum 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 new two-piece subframe for 2023 ensures exceptional strength and durability at an overall weight of just 3.9 lb (1.8 kg). 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

Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps ensure precisely calculated geometry for assured stability. 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.

WP XACT front suspension

The 48 mm WP XACT forks feature a closed cartridge system and a capsulated, adjustable air spring. Together with a pressurised oil chamber, the forks deliver a smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with the mid-valve damping system, the forks provide precise feedback to the rider. To ensure maximum forward momentum after heavy landings, a hydrostop applies a progressive damping force in the last 40 mm of travel. 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. Additionally, the pump needed to adjust the air spring pressure in the forks is provided with each Heritage machine.

WP XACT shock absorber

Inside the WP XACT rear shock is a Computational Fluid Dynamics (CFD) optimised main piston for exceptional comfort with the overall design of the shock providing strong hold-up in all conditions. The linkage system features low-friction seals for unrestricted suspension performance with a lightweight bolt utilised to save weight. Rebound and high and low speed compression settings can be easily adjusted by hand to simplify any set-up changes.

Swingarm

The swingarm is manufactured using a die-cast production process for optimal rigidity. To optimise and match the flex characteristics of the chassis, a 22 mm rear axle is utilised. Additionally, the chain slider is exceptionally durable while the chain guide is manufactured with a rounded profile to ensure it is less prone to catching on external objects.

03. Effortless ergonomics

Functional bodywork

Clean, Swedish-inspired design and ergonomics are tailored to allow riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points and surfaces in the rider triangle have been repositioned for 2023 to improve comfort on the motorcycle. A flat seat offers unrestricted movement with a high grip, ribbed seat cover ensuring riders stay firmly in place under hard acceleration.

Airbox

A strong, one-piece airbox with optimised air intake tracts ensure an unrestricted flow of air for maximum power. The Twin Air filter is easily accessed without tools, by simply removing the left side panel for easy maintenance.

Hydraulic clutch

The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in every condition. With this hydraulic system, free 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 exceptional reliability of the high-quality Brembo hydraulic system.

Hydraulic brakes

The highest levels of quality and performance are guaranteed as the class leading Brembo brake calipers are made from single pieces of aluminium for exceptional strength at the lowest possible weight. Together with a 260 mm front and a 220 mm rear disc, which are designed to prevent mud build-up, superior stopping power and braking confidence is guaranteed in all conditions.

ProTaper handlebar

Developed between Husqvarna Motorcycles and leading handlebar manufacturer, ProTaper, the exclusive bend offers superior comfort, class-leading strength, and fatigue resistance at the lowest possible weight. On top sits the black ProTaper handlebar pad adding style and safety.

ODI grips

ODI lock-on grips feature an innovative, integrated throttle mechanism and are installed without using glue. The throttle assembly offers easy free-play adjustment with the option to fit alternative cams for a personalised throttle action.

Footrests

The CFD-designed footrests are extra wide to ensure better control of the machine while at the same time they are less susceptible to catching on deep ruts, take-offs when scrubbing, and trackside barriers. This was achieved by the narrow mounting design in the frame layout.

05. Technologically advanced

EFI

The electronic fuel injection system on the TC 150 Heritage model brings many benefits. The ECU constantly analyses the running condition of the engine and guarantees to deliver the perfect air/fuel ratio at all times through the state-of-the-art 39 mm Keihin throttle body. EFI also introduces two different engine maps, which can easily be activated via the handlebar-mounted switch for a personalised riding experience. Map 1 (white) is the standard map for linear, progressive power designed for hard pack while Map 2 (green) is more aggressive and suited to sand and heavier track conditions.

E-Start

To ensure fast starting in all conditions, the TC 150 Heritage model features a highly reliable electric start. The system removes the need for a kickstart completely and the additional space created above the engine is used to house the EFI and electronic exhaust control. With the 12.8V 2 Ah Lithium-Ion battery located under the seat and close to the centre of gravity, the handling of the TC 150 is uncompromised. The engine is easily started and stopped via the same handlebar-mounted switch for ease of use.
