2006 Suzuki Boulevard M109R

Written by  April 30, 2006

I recently stopped by Donnell’s Motorcycles in Independence, Missouri to check out the new 2006 Suzuki Boulevard M109R. This awesome looking motorcycle is Suzuki’s largest motorcycle to date, and I’m convinced it will be one of the top 10 motorcycles of the year.

The M109 not only looks good, it performs like a serious mid-weight sport bike, from the inverted front suspension to the 240 mm rear tire setup. The Boulevard M109R's performance begins with its all new 109-cubic-inch, fuel injected V-Twin engine, which provides massive torque all the way from idle to redline, which gives it better acceleration than bikes of similar weight and size. According to Suzuki, this is the most powerful V-Twin they have ever produced.

The exhaust is very unique and has a throaty, distinctive sound that is all Boulevard. One look and you will agree, this new cruiser is one of the best you’ve seen in a long time, plus it has the horsepower to back it up. Suzuki has always been a cut above the rest, from the GSXR 1000 and the Hayabusa; however, seeing this bike and twisting its throttle may change the way you look at the metric line of cruisers.

Larry James and Stewart Basey at Donnell’s Motorcycles is adding a nitrous system to an M109 and I can’t wait to see the dyno results. I have a feeling that number may climb to 170 horsepower or more. I’m also sold on the shim-under-tappet design cylinder arrangement Suzuki has applied. That in itself tells me this bike is no joke and can be revved hard and long for some serious fun.

Below are the engine and chassis specs that prove this bike has been given a rebirth and a place in the spotlight for 2006.

Powerplant
New 1783cc, 4-valve DOHC, 54 degree, liquid-cooled, fuel injected V-Twin engine designed for strong throttle response and quick acceleration

Massive 112mm bore and 90.5mm stroke utilizing huge 112mm forged aluminum alloy pistons with short skirts, and cut away sides riding on chrome moly steel connecting rods.

Unique new two-stage cam drive system creates a compact cylinder head design and reduces overall engine height and creates a lower center of gravity.

Each bore is lined with Suzuki's race proven SCEM (Suzuki Composite Electrochemical Material) for optimum heat transfer, tighter piston-to-cylinder clearances and reduced weight.

A compact dry sump lubrication system SASS (Suzuki Advanced Sump System) provides reduced engine height, a lower crankshaft position and lower center of gravity.

Five-speed transmission features carefully selected gear ratios for comfortable cruising in a variety of riding situations.

Three-piece airbox uses dual intakes with 9.5 liters of internal volume working through a pleated fabric air cleaner element.

The 2-into1-into2 stainless steel chromed exhaust system features Suzuki's digitally controlled SET (Suzuki Exhaust Tuning) system for optimum engine performance and powerful V-Twin sound.

Electronic fuel injection system features the Suzuki Dual Throttle Valve system (SDTV) with 56mm throttle bodies - maintains optium air velocity for smooth low-to-mid range throttle response.

A new Idle Speed Control (ISC) system improves cold starting and stabilizes engine idle speed in various conditions.

Dual spark plug per cylinder ignition system is controlled by the powerful 32 bit ECM for improved combustion effeciency and reduced exhaust emissions.

Race proven front brake system includes radial mounted four piston front calipers and 310mm front brake rotors. Rear brake system includes a dual piston caliper and 275mm rear disc.

Chassis Frame
High-tensile double cradle steel frame is built to comfortably handle all the power and torque while delivering agile handling and a plush smooth ride.

Spiral spoke cast aluminum alloy wheels measure a 3.50 x 18 inch up front and a massive 8.50 x 18 inch rear tire wearing a huge 240mm rear Dunlop radial tire.

The M109R features a muscular, innovative and stylish new look of high performance with long sleek flowing lines and a powerful V-Twin engine.

A sleek wide fuel tank with 5.1 gallon fuel capacity that flows into integrated side covers, a comfortable low seat and stylish radiator cowl.

A streamlined headlight cover carrying a unique trapezoidal shaped multi-reflector H4 halogen headlight and a maintanance free LED tail light built into the tail section.

A handlebar mounted digital tachometer and LED indicator lights flow nicely with the tank mounted analog speedometer and LCD odometer, dual tripmeters, fuel gauge and clock, which I might add is the most unique setup that will get plenty of attention.

Inverted cartridge forks with 46mm stanchion tubes proved an aggressive front end look with 5.12 inches of wheel travel.

A cast aluminum alloy swingarm works with a progressive shock linkage and a preload adjustable single rear shock delivering 4.66 inches of wheel travel working through a shaft drive system.

Suzuki also offers a 12-month unlimited mileage warranty on the M109R.

So as you can see, the new Boulevard M109R is for real and will not only turn heads, but will also get you down the road quicker, cleaner and with one of the best looking stances I’ve seen in a long time.
