Suzuki Boulevard C109R / Intruder C1800R

SUZUKI BOULEVARD C109R / INTRUDER C1800R Features

• 1783cm³ (109 cubic-inch) DOHC 54-degree V-Twin engine created to redefine the term “broad powerband”, and delivering its best throttle response and acceleration.
• Huge 112mm (4.4-inch) forged aluminum-alloy piston. There are one of the largest reciprocating gasoline engine pistons being used in any production passenger car or motorcycle, while featuring race-proven design to reduce friction and inertial mass.
• The pistons each carry an efficient L-shaped upper compression ring, and hard, smooth chrome-nitride Physical Vapor Deposition (PVD)-coated oil control rings reducing friction while improving cylinder sealing.
• Lightweight aluminum cylinder with Suzuki Composite Electrochemical Material (SCEM) cylinder coating to improve heat transfer, durability and weight reduction.
• Each combustion chamber comes with dual spark plugs producing more efficient combustion and lower emissions.
• Suzuki Advanced Sump System (SASS), a compact dry-sump lubrication system, and a two-stage chain drive system makes for a low-slung engine.
• Strong multi-plate clutch with the engine balance shaft sends power through the 5-speed transmission and to the clean, smooth-running shaft drive.
• Advanced digital fuel injection and engine management system using a powerful 32-bit processor for greater power output, throttle response and fuel mileage.
• Suzuki Dual Throttle Valve (SDTV) downdraft throttle body design helps maintain the proper intake air velocity for improved low-to-mid rpm throttle response.
• Automatic Idle Speed Control (ISC) system helps maintain a stable idle while improving cold starting.
• Control measures allow to meet tough Euro 3 and TIER 2 emissions regulations standards include Pulsed-secondary AIR-injection (PAIR) system and muffler catalyzes.
• Lustrous chrome plating and highly polished aluminum parts highlight the details of the SUZUKI BOULEVARD C109R/INTRUDER C1800R powerplant.
• Road-smoothing chassis geometry: 1,755mm (69.1-inch) wheelbase, 32-degree of rake and 130mm (5.1-inch) of trail.
• Telescopic front forks nicely finished with hefty 90mm chromed tube covers.
• Hidden behind the classic hardtail-like rear end is a swingarm suspension using a spring-preload-adjustable shock absorber.
• Generous front 130mm (5.1-inch) and rear 118mm (4.6-inch) of wheel travels make for smooth rides solo or with a passenger.
• The common-sense riding position is meant for comfort on both long hauls and daily short trips with wide and long seat, chromed pullback handlebars, convenient controls and generous floorboards enhance riding comfort.
• Pillion seat made for long-ride comfort as well as elegant looks.
• Suzuki combined brake system using dual 290mm (11.4-inch) floating front disc brakes and a single 275mm (10.8-inch) rear disc brake.
• The front brake lever activates the two outside pistons in each front brake caliper. The rear brake lever activates both rear-caliper pistons, then the front-caliper center pistons. Delay valves smooth front brake actuation.
• Cast aluminum-alloy radial 10-spoke wheels, shod with 150/80R16 M/C 63V front and a massive, ultra-wide 240/55R16 M/C 79V rear tires.
• Genuine long-volume hand-crafted steel fenders featuring rolled edges. Chrome-plated steel supports accent the deep rear fender.
• Wide-body 19-liter (5.0 US gallons) steel fuel tank topped by a chrome instrument cluster carrying analog speedometer, LCD odometer and trip meter, clock and fuel gauge and other indicator lights.
• 180mm (7.0-inch) multi-reflector halogen headlight carried in classic chromed housing, and durable, bright bullet-shape turn signals and LED taillight.
