The Yamaha XSR900 and the Yamaha YZ450F have been
showcased at the 2017 Tokyo Motor Show. The Yamaha XSR900 belongs to the
Japanese brand’s Sports Heritage product family. Authentic design elements like
the circular headlight and tail lamp; muscular fuel tank with riveted tank
cover, and drilled headlamp stays make it a proper neo-retro motorcycle. The
multifunction digital instrument cluster also follows the circular theme.
The XSR900’s engine is an in-line three-cylinder
DOHC unit with liquid cooling and fuel injection. The powerplant produces a
peak power of 116 PS at 10,000 rpm and 87 Nm of torque at 8,500 rpm. The engine
mates with a 6-speed gearbox with assist and slipper clutch. The bike features
Yamaha’s D-mode with three throttle maps. Switchable Traction Control,
immobiliser and ABS are standard as well.
Upside down front forks and rear monoshock handle
the suspension responsibility. The motorcycle comes to a halt using twin 298 mm
dual discs with radial callipers at the front; and a single disc at the rear.
Yamaha’s off-road motorcycle the YZ450F, in its
third generation features a plethora of changes to make it faster, lighter and
handle better. Yamaha has blessed the bike with an all-aluminium bi-lateral
beam frame, bigger KYB speed-sensitive upside down front fork and a stronger,
lighter rear monoshock.
The Yamaha YZ450F sources its power from a 449cc
single cylinder DOHC engine with liquid cooling and fuel injection. The engine
works in tandem with a 5-speed transmission. Yamaha has tuned the powertrain
for optimal power delivery, but the company has not specified the power and
torque output. The bike’s unique feature is the new Power Tuner which can tune
the engine’s characteristics using a smartphone app.
For lighter weight, the bike comes with a
lithium-ion battery as well. The motorcycle weighs 111 kg, wet. The Yamaha
YZ450F costs 1,015,200 Yen (MSRP) in the Japanese two-wheeler space.
