The name Tnr has been synonymous with Yamahas rugged Adventure Sport dual-purpose models since the original machine was first launched in the early 1980s. Developed from Yamahas highly successful Dakar race-winning factory bikes, the original Tnr models built up a huge following of loyal owners during the 1980s and 90s.

With an unrivalled reputation for durability, strong on and off road performance, high levels of long-distance comfort, and the ability to handle hostile off road terrain, the machine was one of Yamahas best-selling models throughout Europe.

Such was its go-anywhere, do-anything reputation, that it became the machine of choice for numerous round-the-world travellers, and to this day the original Tnr and its successors have probably clocked up more orbits of the earth than any other single-cylinder motorcycle. And at the same time as being the number one choice with adventure-seekers, the original Tnr also became a favourite with riders looking for a tough, reliable and stylish all-rounder that could perform well in almost any environment.


For 2008 Yamaha introduce the all-new XT660Z Tnr that is designed offer a new generation of adventure-seeking riders the opportunity to explore a new world of possibilities. True to the original go-anywhere design philosophy.

Yamaha has more experience in the design of rugged and reliable large-capacity 4-stroke single-cylinder engines than any other leading manufacturer. The famous Dakar Rally was inspired by the original XT500 model way back in the 1970s, and since then Yamaha has been at the very forefront of big-single design.

High-torque 660cc liquid-cooled engine

Powering the new XT660Z Tnr is a 660cc liquid-cooled 4-stroke single cylinder SOHC engine which has been tuned to deliver strong low to mid-range power. This gutsy powerplant makes the Tnr 660 a strong performer in a wide range of riding situations, from urban commuting through to highway touring and off road exploring.

4-valve head and fuel injection

Equipped with a highly efficient 4-valve cylinder head with a 10:1 compression ratio, and featuring bore x stroke dimensions of 100mm x 84mm, the new fuel-injected Tnr engine delivers excellent throttle response for lively off-the-line and roll-on acceleration.

5-speed transmission

The smooth-shifting 5-speed transmission is equipped with carefully chosen gear ratios that are designed to optimise the bikes strong low to mid-range torque output, and the 2.9 litre transmission oil capacity ensures efficient engine operation even under severe conditions.

The XT660Z Tnr is equipped with an all-new chassis whose rugged, go-anywhere character perfectly complements the big-single engine. The extremely strong yet new light semi-double cradle frame is compact and slim, and has been designed to offer an optimum balance of strength and rigidity for good handling qualities on and off road.

Long travel suspension; aluminium swinging arm

In order to deliver high levels of rider and passenger comfort, and to be able to take handle a variety of off road terrain, the new Tnr is equipped with long-travel forks which give 210mm of front wheel movement.

Complementing this rugged front suspension is a lightweight aluminium swinging arm, which reduces unsprung weight for enhanced rear suspension performance, and offers 200mm of rear wheel movement thats designed to soak up the bumps.

This generous amount of suspension travel at the front and rear not only makes the Tnr one of the most comfortable machines to ride in any situation it also ensures good handling performance over poorly maintained paved roads and across pure off-road terrain.

Long-range fuel tank

Underlining the machines serious long-distance potential is a large-capacity 22-litre fuel tank which blends seamlessly with the beautifully sculpted front cowl. Despite its generous capacity, the width and height of the fuel tank is kept to a minimum by extending the fuel tank beneath the riders seat, which has the added advantage of helping to centralise mass for neutral handling characteristics.

Wind-beating front cowl

With its upright riding position and long dual seat, the Tnr is an extremely comfortable machine, whatever the journey, whether its from home to work or across a continent. To help reduce rider fatigue on long journeys this rugged new all-rounder is equipped with a stylish front cowl and tall screen which deflect wind away from the upper body.

For a distinctive new look, a new dual-bulb headlamp assembly with a vertically stacked low and high beam is used. As well as projecting a powerful beam, this new over and under assembly keep the cowls frontal width to a minimum for improved aerodynamics.

For efficient stopping power the new Tnr is equipped with dual 298mm discs gripped by 2- pot calipers. This high-specification system ensures strong and controllable braking performance, as well as offering plenty of feel .

Bodywork and engine protectors

With its class-leading go-anywhere abilities, the XT660Z Tnr is ready to encounter rugged terrain, and in order to handle the most severe conditions the new model is equipped with a range of lightweight protectors.

The front cowl features durable protectors on either side of the bodywork which help prevent accidental damage, while the engine is also equipped with lightweight guards on either side of the cylinder. And to help prevent damage when riding off road, the engine cases are also fitted with compact guards. Each of these protectors can be easily replaced if they are damaged, allowing the owner to keep their machine in first class condition.

Wide range of quality accessories

Yamaha have also developed a comprehensive range of accessories for the new Tnr, allowing riders to enhance the specification of their bike to suit their own requirements.

Riders wishing to enhance the luggage carrying capacity of their bike have the option to fit genuine Yamaha side cases or a top case, as well as a tank bag.

Hand guards, engine guards and a skid plate are available for owners looking for extra protection on their riding adventures while the wind deflectors help keep hands warm and also act as brush guards when riding off road.

An optional main stand is available to facilitate tasks such as wheel removal when repairing punctures on long trips, and a tank pad is available to help prevent the minor scratching to the paintwork that can sometimes be caused by zips and buckles.

And finally, riders wishing to give their new Tnr an even gutsier exhaust note may wish to fit the slip-on Akrapovič muffler offered by Yamaha.
