The heart of the new Husqvarna TR 650 Strada and TR 650 Terra is the single-cylinder 4-stroke engine familiar in its essentials from the BMW G 650 GS with 100 mm bore, 83 mm stroke, four valves, two overhead camshafts, electronic fuel injection and twin-spark ignition. Power transmission is by means of a constant-mesh 5-speed gearbox, with secondary drive provided by a low-maintenance O-ring roller chain. For use in the two new Husqvarna models, however, the engine has undergone extensive technical modifications in order to increase its output.
With 43 kW (58 hp) at 7,250 rpm, it has 8 kW (10 hp) more output than the basic BMW Motorrad engine, providing particularly powerful, dynamic providing particularly dynamic power, both for riding on country roads and over light terrain, especially in conjunction with its relatively weight of just 186 kg (TR 650 Strada) or 183 kg (TR 650 Terra without ABS) fully fuelled. A reduced power version with 35 kW (48 hp) at 7,250 rpm and 54 Nm torque at 5,750 rpm is also available as an ex works option (US Version n.a.).
Newly designed cylinder head with optimised duct layout.
A whole package of measures has been put together to achieve the high peak output of 43 kW (58 hp). For example, a new mould was developed for the cylinder head so as to produce even more aerodynamically optimised ducting of the intake and outlet ducts for increased power. As part of the redesign of the cylinder head, the spark plug thread was also reworked, involving a reduction in thread diameter from 12 to 10 mm. This results in an even more effective flow of cooling fluid in the spark plug area as well as enhanced heat dissipation and therefore a more favourable engine thermal dynamics.
Increased compression, new camshafts, larger valves.
Other features which contribute to the increased engine output are a new fuel-injection system, newly-designed camshafts with longer timing, new valve lift curves and deeper valve strokes. In combination with enlarged valve head diameters in the intake and outlet valves, the optimised intake and outlet camshaft enables improved filling and a more effective charge cycle. Another contribution to the performance enhancement of the single-cylinder engine is the increase in the compression ratio from 11.5 to 12.3:1.

Forged piston, weight-reduced crankshaft and counterbalancing shaft
The developers responded to the increased combustion pressures and the resulting higher level of mechanical stress by using a high-quality forged piston. In addition to increased stiffness and therefore reliability, the new piston also contributes a weight reduction of 112 grams (432g to 544 g). The crankshaft and counterbalancing shaft were adapted accordingly to this shift in weight balance. The reduction in oscillating and rotating masses makes for increased revving but with low-vibration running.
The periphery of the engine was also adapted to these modifications and new properties. As a result, the new TR 650 Strada and the new TR 650 Terra have a newly-designed intake silencer as well as a high-quality exhaust system made of stainless steel including two rear silencers. Exhaust gas cleaning is performed by a closed-loop 3-way catalytic converter.
Low fuel consumption and an impressive range.
The high compression ratio of the engine at a level of 12.3:1 is designed for a fuel quality with an octane number of at least 95 RON, making for impressively low fuel consumption figures in spite of its high output. For example, it uses just 3.2 litres per 100 km/h (88.3 mpg) at a constant speed of 90 km/h (56mph) and less than 4.3 litres per 100 km (65.7 Imp. mpg) at a constant level of 120 km/h (75mph). In conjunction with a fuel tank offering a capacity of 14 litres (3,08 Imp Gal) (US-Version: 13,5 3.57 US gal), housed under the seat, this allows ranges of more than 350 kilometres (217 miles).
Agile, directionally-stable chassis for dynamic riding fun, both on asphalt and off the road.
In keeping with the bikes' concept-based aspirations, the chassis of the new Husqvarna models TR 650 Strada and TR 650 Terra are designed for maximum agility and carefree motorcycling enjoyment both on-road and off-road, though without having to compromise in terms of comfort and touring suitability. What is more, ride stability, steering precision and agility instantly promote a sense of trust even in beginner motorcyclists.
The new TR 650 Strada and the new TR 650 Terra are fitted with a torsionally stiff split-backbone steel frame with bolt-on steel tube rear frame and front beam bolted onto the engine. The dual swing arm is also made of steel and fitted with two torsionally stiff swing arms made of pentagonal tubing. With its constructional design and specific benchmark data such as 1,501 mm (59.1“) wheelbase and 64° (Strada) – 63.5° (Terra without ABS) – 63° (Terra) steering head angle, the torsionally-stiff chassis meets the requirements for excellent handling, a high degree of directional stability and the robustness which is essential for off-road riding. Another key factor in the new Husqvarna TR 650 Strada and TR 650 Terra in terms of agile handling is the positioning of the fuel tank under the seat, which results in a lower centre of gravity.
Steering as well as suspension and damping are taken care of at the front by an upside-down 46 mm telescopic fork. At the rear, the swing arm is supported on the frame by means of a central rear shock with progressive linkage. The rear shock allows adjustment of the compression and rebound damping so as to be able to adapt to individual needs. Suspension travel at front and rear is 190 mm. The suspension elements of the TR 650 Strada and TR 650 Terra do justice to the different areas of use of the two bikes with specially adapted suspension/damping settings.
Wheels, tyres and seating position adapted to function.
In keeping with its intended use on asphalted roads the Husqvarna TR 650 Strada is fitted with 10-spoke light alloy cast wheels and 110/80 R 19 59V and 140/80 R 17 59V road tyres, front and rear. The Husqvarna TR 650 Terra meets the requirements for riding over light terrain, featuring spoke wheels (36-hole) with rims and hubs in light alloy. The appropriate tyres are fitted for more intense off-road use, with 90/90-21 MC54HTL and 140/80 17 MC59H being used in conjunction with ABS and 90/90-21MC54 S and 140/80 18 MC70 S used on the non-ABS version, at the front and rear, respectively.
There are also differences between the new Husqvarna models in terms of seating position. When riding off-road, the rider of the TR 650 Terra (with ABS) enjoys a seat height of 865 mm/34.1” (without ABS: 875 mm/34.5”). Due to the different wheel configuration, the TR 650 Strada’s seat height is even lower, at 860mm/33.9”.
Highly stable brake system. TR 650 Strada with ABS as standard.
With a 300 mm disc brake at front and a 240 mm disc brake at rear, the new Husqvarna TR 650 Strada and TR 650 Terra offer stable, secure and well-controlled stopping power. For even greater safety when braking, the new Husqvarna TR 650 Strada is fitted as standard with ABS, while the TR 650 Terra can likewise feature ABS if this is ordered as an ex works option. The ABS is also disengageable in both models for special requirements.
Ergonomics, fittings and design.
With their favourably-shaped, 875 mm / 34,5 “ wide handlebars, the new Husqvarna TR 650 Strada and TR 650 Terra provide a relaxed, athletic seating position for excellent vehicle control and agile handling. The grips of both the handbrake and clutch levers can be individually adjusted. Ergonomically-conceived handlebar panels ensure intuitive and safe operation of the various vehicle functions. The digital instrument cluster with easily readable, clearly-defined LCD display provides compactly-presented information on road speed and engine speed. The unit also features two trip counters and a clock. LED lamps are installed for the functions of turning indicators, high beam and injection system as well for providing feedback on fuel reserves. Both models are fitted with a vehicle immobilisation function as standard.
The TR 650 Strada and TR 650 Terra likewise embody agility and riding dynamics in their design, with special dynamically-shaped body panels. The masculine styling of the bikes points to the active, athletic aspirations of the two models, with their clean lines reflecting lightness and agility. White turning indicators and a headlamp in clear-glass look are unobtrusively integrated, harmonising perfectly with the overall design. The distinct usage profiles of the TR 650 Strada and TR 650 Terra are reflected in individual wheel accentuations. While the TR 650 Strada is oriented towards dynamic performance and riding fun on asphalted roads with its light alloy cast wheels and front fender in white placed directly above the front wheel, the
TR 650 Terra hones its off-road profile with spoke wheels in conjunction with a white fender positioned high above the front wheel.
Body features in red in the front and rear section along with black-coated components such as frame and swing arm give the TR 650 Strada and
TR 650 Terra a colouring which embodies high-spiritedness and athletic flair. Meanwhile the sand-blasted, light grey surfaces of the engine in conjunction with the hallmark Husqvarna red cylinder head in the two new Husqvarna models offer a contrasting element which emphasises powertrain expertise. An additional contrasting touch which highlights the bikes' technology is also provided by the exhaust system in brushed steel as well as the silver anodised fixed fork tubes of the upside-down fork.
Even in serial production trim, the new Husqvarna TR 650 Strada and the new Husqvarna TR 650 Terra almost perfectly fulfil the requirements of a dynamic road or off-road bike designed for active riding. In addition, Husqvarna Motorcycles offers an extensive programme of options and special accessories for further individualisation.
