Yamaha showed off its new addition to the
Star Bolt lineup of retro-styled middleweight cruisers, the Bolt C-Spec.
The C-Spec gives Bolt riders a more sporting
option, and it isn’t just dressed up for the part. In addition to the special
paint and trim and restyled solo seat (with attached cowl), the C-Spec gets
clip-on handlebars and rearset (more mid-mount, really) pegs to get the rider in
a riding position that is more standard than cafe, but still better suited to
twisty roads than the feet-forward position of the regular Bolt. The instruments
are relocated to adjust for the hunched over rider. Yamaha product planner Derek
Brooks told us it has “sport-tuned” suspension, giving it the handling chops to
match its looks.
The World's 1st Urban Performance Cafe Racer An instant
cafe-racer classic, the all new 2015 Yamaha Bolt C-Spec features everything that
makes the Bolt great - minimalist design, powerful fuel-injected 942cc V-Twin,
great handling, and ads cafe racer styling, sporty clip on handlebars, footpegs
set further back for a more athletic riding position, and slim solo seat.
Available in two colors: Deep Green and Simple Silver.
Introducing the latest addition to the Bolt family... the 2015 Bolt C-Spec.
Offering class leading performance and a fun filled ride, the new Bolt C-Spec
features low slung clip-on handlebars, a cool solo seat with rear seat cowl and
a new, more sporty riding position. Perfect for unwinding after a hard day's
work, the Bolt C-Spec returns riders to the roots of motorcycling with a
uniquely styled model, offering the sound and "character" that only an
air-cooled V-twin can provide.
Performance
The Bolt C-Spec uses modern technology to create a superior
riding experience. At its heart, is a traditional 942cc
air-cooled V-twin engine with a modern twist. Ceramic composite
plated cylinders, dual bore fuel injection and 4-valve cylinder
heads to name a few.
Substance & style
The Bolt C-Spec invokes the timeless character and soul of a
café racer. We've kept the centre of gravity low and centralized
the mass to provide a light, agile handling machine that offers
a truly enjoyable riding experience. Pure style, pure
simplicity, pure fun.
•NEW FOR 2015! The Bolt C-Spec epitomizes the cool “Café” style
popular across the globe since the 1960’s. Bolt C-spec features
café styling with original Star v-twin performance and includes
clip-on handlebars, traditional fork boots, a removable
passenger seat cowl, and sporty café paint and graphics that
makes the Bolt C-Spec ultra-cool.
•The compact chassis proudly showcases the enormously popular 58
cubic inch (942cc), air-cooled, 60° V-twin Bolt powerplant that
has been a huge hit on the showroom.
•The Bolt C-Spec uses modern technology to create a riding
experience superior to other similarly sized machines. Fuel
injection and ignition timing maps have been set to deliver
class-leading performance with strong low- and mid-range torque
sure to bring a smile to every rider’s face.
•A belt drive is used to deliver power to the back wheel
resulting in an almost maintenance free final drive system that
is both durable and reliable.
•Designers and fabricators will love the real steel fenders and
belt design as they take the Bolt C-spec and fulfill the Star
mantra of “we build it, you make it your own”.
Engine
• 942cc, air-cooled, SOHC, 4-valves per cylinder, 60° V-twin
engine produces outstanding low- and mid-range torque. Maximum
torque is reached at only 3,000 rpm - for an exceptionally fun
riding experience.
• One-piece cylinder heads feature 4-valves per cylinder to
provide optimum filling efficiency for maximum power output. The
benefit of a 4-valve design is two smaller valves allow more air
flow and a higher rpm limit than a single heavier larger valve.
• Pent roof combustion chamber design with optimized squish area
forces the fuel / air mixture toward the centre of the
combustion chamber (and the centrally located long reach spark
plug) for faster, more complete combustion, improved power and
reduced emissions.
• The SOHC valve train features 31.5mm intake and 28mm exhaust
valves with single valve springs which reduce friction and power
losses. Specially designed "Y" shaped roller rocker arms
activate the valves and utilize needle bearings that "roll"
directly on the cam lobes allowing the lift of 2 valves at the
same time without producing excessive camshaft wear and
friction.
• Auto adjusting cam chain tensioners are used to reduce
mechanical engine noise and maintenance
• Lightweight, "liner-less" aluminium cylinders feature ceramic
composite plating for superior heat dissipation for excellent
cooling, less friction and reduced weight. Cylinder cooling fins
feature brushed aluminum highlights.
• Single pin style crankshaft is used to enhance V-twin engine
character and exhaust note.
• Lightweight forged aluminium pistons provide excellent
durability while reducing reciprocating mass for fast throttle
response.
• Wet sump oil delivery system features an easy access spin-on
type oil filter and easy access drain plug. A traditional
dipstick is used to check oil level.
• Classic side mounted, 2.3 litre air box houses an easy access,
high-flow viscous paper-type filter. The outer cover features
brushed aluminum highlights.
• Dual bore, 35mm throttle body fuel injection system with TPS
(Throttle Position Sensor) and ISC (Idle Speed Control). This is
a "closed loop" system that utilizes a heated oxygen sensor,
which feeds back info to the ECU which in turn adjusts the
fuel/air mixture for maximum power with minimum emissions. The
Idle Speed Control (ISC) maintains a steady idle regardless of
engine temperature.
• 4-hole, 2-directional spray, Denso fuel injectors are used for
excellent fuel atomization and more complete combustion chamber
filling. There is one injector per cylinder.
• Fuel injection benefits include; excellent fuel economy,
choke-less starting, reduced emissions, and smooth
drive-ability. The Bolt C-Spec has been tuned to provide a very
"linear" throttle response for easy riding.
• Maintenance-free transistor controlled ignition (TCI) provides
a hot spark for sure starts and strong engine performance.
• Powerful 32 bit ECU controls the ignition and fuel injection
processes.
• Multi-plate "outer pull type'" wet clutch is used. Lever pull
is light and easy.
• 5-speed transmission features optimized gear ratios for
excellent city and highway ride-ability. Transmission gears use
"straight cut dogs" for smooth, positive shifting. 5th gear
delivers outstanding cruising performance and reduced rpms at
highway speeds.
• Clean, quiet belt drive system is extremely low maintenance
and simplifies customization. The 21mm narrow design belt
utilizes carbon fibre cords for excellent strength and reduced
stretching.
• Air Induction System (A.I.S.) reduces harmful CO and HC
exhaust emissions.
• Stylish 2 into 1 exhaust system features a 3-way
honeycomb-type catalyzer at the entry point of the muffler to
reduce emissions. The rear header pipe "snakes" toward the front
cylinder in order to provide the necessary tuned length, not to
mention it is a key styling highlight too. The short design
"dual stage type" muffler produces a low, throaty V-Twin exhaust
note.
SUSPENSION
• Tube type, single backbone, double cradle steel frame offers a
natural riding position, roomy ergonomics and a low seat height.
This frame utilizes a 4-point rigid engine mounting system to
optimize the overall rigidity balance for superior handling. The
engine is mounted low in the chassis to provide a low center of
gravity for light, easy handling.
• Conventional tube-type, steel, short design swingarm
compliments the frame and utilizes a dual shock suspension
system.
• The Bolt C-Spec features a 765 mm / 30.1" seat height and a
very narrow design through the seat-fuel tank junction allowing
many riders to place both feet flat on the ground.
• The compact 1570mm / 61.8" wheelbase provides light, agile
handling, for a fun riding experience.
• The Bolt C-Spec is designed to be compact and slim, featuring
clean, simple styling with the ability to easily personalize /
customize the bike with a wide range of Genuine Star
accessories. The styling is "Star Original Bobber" with a
classic café racer twist. The design invokes a sense of dynamic
forward motion and concentrated mass. The engine features "raw
metal" styling highlights.
• 41mm front fork features classic styled rubber fork boots
(aka. gaiters) to not only add a styling highlight but to also
protect the fork tubes and seals. Wheel travel is 120mm (4.7").
• Lightweight, forged aluminum upper triple clamp and forged
steel lower triple clamp. The "pitch" between the fork tubes is
190mm or 7.5", which is well proportioned to 100/90 series front
tire.
• Adjustable premium dual, remote reservoir gas shock rear
suspension. Rear wheel travel is 70mm (2.8"). The 5-positions of
spring preload adjustment allows the rider to tailor spring
preload to suit rider weight and load.
• Single, 298mm front disc brake features a floating, wave-style
rotor squeezed by a twin piston caliper for strong,
confidence-inspiring stopping power. The wave-style rotor offers
more surface area than a conventional round disc for excellent
heat dissipation.
• 298 mm rear disc brake is squeezed by single piston caliper
mounted to the underside of the swingarm. This design not only
helps to hide the caliper but also lowers the center of gravity
for light handling.
• Lightweight aluminum clip-on handlebars reinforce the café
racer styling.
• New, more compact handlebar switches, front brake master
cylinder, and levers provide a more sporty image.
• 12 litre teardrop shaped fuel tank compliments the slim,
compact design of the Bolt C-Spec.
• Rider only solo seat offers excellent comfort and that special
Café racer style. The seat is 765 mm or 30.1" from the ground.
An optional passenger seat kit will be available.
• Repositioned footpegs are 150 mm ( 5.9") rearward and 29 mm
(1.1") higher than the regular Bolt & R-Spec. Combine this with
the revised handlebar position and you have an all new, more
sporty forward leaning riding position.
• Short design front and rear fenders are made of steel for easy
customization and demonstrate the quality of build.
• Lightweight 12-spoke cast aluminium wheels are fitted with
tubeless tires. Front wheel is an MT2.50x19 fitted with a
100/90-19 bias tire, while the rear is an MT3.50x16 fitted with
a 150/80x 16 bias tire.
• LCD digital meter assembly features a speedometer, odometer,
dual trip meters, fuel reserve trip meter (counts kilometres
since low fuel warning light activated) and a clock. Warning
lights include; low fuel, oil level and engine trouble. The
instrument has been re-positioned to match the Café styling.
• 60/55 watt halogen headlight
• "Vintage design" LED tail light features 19 LED's for
excellent visibility. Chrome bezel adds another styling
highlight.
