After the XSR155, Yamaha is working on a
dual-purpose WR155 motorcycle, which will share its underpinnings with the
YZF-R15 V3.0. Thus, the WR155 will use the company’s tried and tested Deltabox
frame. The sub-frame is likely to receive changes to match the dual-purpose
character of the motorcycle.
The engine specifications will be identical to the
YZF-R15 V3.0 and the XSR155, and the WR155 will draw power from a 155 cc
liquid-cooled, single-cylinder motor with 4-valve and Variable Valve Actuation
(VVA) technology. The power mill of the YZF-R15 V3.0 churns out 19.3 PS at
10,000 rpm and 14.7 Nm at 8,500 rpm, and the figures are not likely to be much
different on the WR155. Yamaha may tweak the gear-ratio for the dual-purpose
motorcycle.
Hardware specifications for the international-spec
WR155 will include inverted front forks. Given the WR155’s dual-purpose
character, the motorcycle will most likely get a longer travel rating for the
suspension setup. Anchoring department will comprise single discs on both
wheels while the ABS tech, unlike on the YZF-R15 V3.0, is likely to be
switchable.
The dual-purpose motorcycle styling cues will
include a tall-set front fender along with a LED headlight on the front fascia.
The lean fuel tank and saddle will offer plenty of room to move around while
off-roading. The seat height will be on the taller side due to the increased
ground clearance, and thus short riders may face some trouble. The exhaust will
be high set for improved ground clearance and better water wading prowess.
The new motorcycle will have a larger front wheel
with a 21-inch diameter for better off-road handling. The wire-spoke wheels
will use dual-purpose, knobby tyres for enhanced traction over loose surfaces
such as gravel and mud. The motorcycle will be street legal, and thus come
equipped with rear-view mirrors, blinkers and a taillight.
Along with the WR155 name, Yamaha has applied a
patent application for a 'WR155R' model as well, thus hinting that the 155 cc
WR model will be sold in two variants. The official unveiling is not expected
to take place anytime soon.
