A new WR450F for 2016, with the reversed engine layout as on the YZ450F with which Romain Febvre won the MXGP world championship title in 2015! In this article we explore its benefits.
A major technical update for 2015: Our WR250F is based on the radical YZ250F motocrosser, with lots of refinements for the specific enduro usage. Let’s have a look at its highlights.
“The goals were very clear for us” says our development engineer. “Better power and optimal handling. So we adopted the reversed-engine layout that was so successful on the 450. At the same time, we didn’t want the power output to be too aggressive. Easy control and overall rideability was our main focus.”
“Our 450 was already the leader of the pack in terms of engine performance” says test rider Erik Eggens. “For pro riders that’s a great feature, though it could also be too much. The new bike has the same high power level, but the power delivery is much more controllable.”
Important model change with fuel-injected engine in YZ250F-based chassis which brings new levels of agility to the 450 class. Bodywork is all-new, with a modern and slim-line design which underlines the 250-class dimensions and also has a 30mm lower seat height than the previous model.
"We wanted to show that the core of the Super Ténéré is very sporty and that with a few changes the bike gets a completely different expression" explains Product Planning manager Oliver Grill.
Product planning says: "This bike is built for adventure, for big loads and long journeys, for far-away places, in line with the previous Ténéré's." Engineering says: "A big bike should still feel nimble. We aimed for perfect handling and great feedback between rider and machine."

This 2010 machine is radically different than its predecessors. Why did Yamaha do this and what were the challenges that the engineers faced?
“The lightweight feeling and controllability from corner approach to ‘on the power’ corner exit is far better than previous models”, our Test Rider announced. “The riding position is much improved as is the clutch feeling, throttle response and engine character. It’s possible to lap consistently faster”.
The YZ400F 4-stroke motocross machine was a revolution in the dirt bike world when it came out in 1998. Yamaha used a free-revving, highly compact engine housed in a light and agile 250-class chassis which proved to be a winning formula.
“The WR125X and WR125R are both serious and aggressive motorcycles, we developed them for young riders who are not prepared to compromise or settle for second best.” explains Hiroshi Komatsubara, President of Yamaha R&D development centre in Milan, Italy. “The WR125X has real supermotard capabilities; the riding sensation is at the edge of the 125cc Motard category. The WR125R is more than capable of exciting riding on the tarmac but excels on the soil and dirt in light off-road conditions.“
“We think it’s time to come back with a renewed concept,” says Ténéré project leader Hiroo Saito. “Yamaha has been absent from the Rally touring segment for a long time. The first Ténéré (see Ténéré history) has influenced the category heavily in 1983. The new XT660Z Ténéré has everything the original concept’s success was made of: It is simple, unbreakable, practical, light and has a reliable, strong single cylinder engine and we made it deliberately fit for off-road as well.”
Back in 1998, a decade ago, Yamaha made history with its first 4-stroke motocross bike YZ400F followed by the enduro WR400F. They were made to compete against 2-strokes, which have been dominating the off-road world for more than 30 years. Yamaha 4-stroke off-road machines celebrate their 10 years anniversary supported by significant model changes on the WR-series in 2007.
The new 125 cc machines are the first choice if you simply want a lightweight bike or you have an A1 license (motorcycle up to 125 cc) and want to enjoy real motorcycle riding. They combine the light weight and good handling characteristics with the components of a real motorcycle. Yamaha test riders believe: " With the new DT 125X you can have a lot of fun and a real Supermotard feeling in particular in tight corners. Its light weight makes it easy to control the machine under all circumstances." Even bigger machines may have difficulties to keep up with this hard edged Supermotard in narrow corners.
On the Tokyo Motorshow of 2001 Yamaha introduced the Tricker concept model, which shortly after went into production and was introduced into the Japanese market.
The "classic" the XT 125R has all the ingredients of the typical Yamaha XT family, being a true dual purpose machine. The 21 inch front wheel and the 18 inch rear with the typical Enduro style tyres make it fit for both road and off-road use. Seat height and ground clearance are higher comparing to the Supermotard version and the machine features the typical dual purpose handling characteristics, which makes it suitable for a wide range of duties, from crossing rough city roads to small country lanes or paths.
Very much inspired by the styling of its bigger brother XT 660X, the 125 cc version is an ideal bike for people who add a few more rational aspects to their purchase criteria. The single four stroke engine makes minimal noise, lower on fuel consumption and delivers a smooth controllable power The bike's riding characteristics are very user-friendly, with only 111 kg dry weight and a relatively low 830 mm seat height. The XT 125X is an ideal machine for youngsters and others being new to the world of 2 wheels.
The two letters XT are still synonymous for big single on-off. And many enthusiasts have been waiting for a new XT for some time. Here it is, in two versions with an updated single thumper and stronger than ever before.
The new 2004 off road models have many detail improvements. Don't look at the obvious, have a glance deeper down behind their bodywork.
The sandy and rocky tracks of the Moroccan desert proved an ideal testing ground for Yamaha's 2 wheel drive rally bike. French enduro rider David Frétigné won the rally and Jean-Claude Olivier, President of Yamaha Motor France scored second.
"Our development goal was straightforward. We wanted to build the strongest motocross machine", says project leader Hayashi-san.
A cross-breed between a motorcycle and a mountain bike, for Takeshi Higuchi, this thought is well within reach. Tricker, the concept model shown at 35th Tokyo Motor show is his brain child. "Not only over here in Japan, we see that young people show less interest in conventional motorcycles. Many of them however grew up on mountain bikes and still love them." Higuchi explains. "The guys we are aiming at have lesser interest in performance. They are more keen on some possibilities of trick riding, like they experienced on their BMX or mountain bikes."
Yamaha add a new dimension to motocross for 2001! When the first production YZ400F appeared on the racetrack in 1998 the image of the 4-stroke motocross machine changed overnight. Light, agile and delivering a wide band of hard-hitting power, the free-revving YZ400F - and its successor the YZ426F - are two of the most successful motocross machines ever produced by Yamaha, both in terms of world-wide race successes and sales volume.
Yamaha has shown a prototype of a YZM 426 WR with a two wheel drive system at Intermot show in September. The reaction of Enduro riders was great. In a questionnaire most of the respondent saw benefits in a two wheel drive for motorcycles. Of course, there were also questions about the system and it's benefits.
What has proved successful in the car world is now a reality in the motorcycle world! 2WD for motorcycles has just as many advantages as 4-wheel drive on cars. Yamaha recently introduced their 2WD TT600R to the media, and this revolutionary dirt bike got a great response from the journalists who tested it. After racing a 2WD TT600R in several rallies from Sweden to Sardinia, the bike has proved to be superior to conventional models, particularly under difficult conditions, such as on mud, sand, gravel and wet surfaces.
