2009 Boulevard C109RT - Pros & Cons

Strengths

Strong power output: 2009 Suzuki Boulevard C109RT makes 92 kW @ 6200 rpm with 160 Nm @ 3200 rpm of torque - competitive figures for its class.
Fuel injection: The fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
Accessible seat height: At 705 mm, the seat height is approachable for a wide range of rider heights and builds confidence in low-speed manoeuvring.
Large fuel range: The 19 L tank is generously sized, translating to extended range between stops - ideal for touring or longer commutes.
Low-maintenance final drive: Shaft final drive means no chain to clean, lube or adjust - meaningfully less routine maintenance than a chain-driven equivalent.

Considerations

Age-related wear: As with any used Boulevard C109RT, a thorough pre-purchase inspection covering consumables, service history and tyres is always recommended.

Wear Points & Servicing Notes

Cooling system servicing

The Liquid cooled system on the Boulevard C109RT needs a coolant change roughly every two years (or per the service schedule) - skipping it lets the coolant turn acidic and corrode the aluminium water passages over time.

Fuelling & injector care

Fuelling comes from fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.

Brake disc and pad wear

The 2 x 310 mm discs, 2 piston calipers front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the Boulevard C109RT runs Telescopic, coil spring, oil damped and Link type, coil spring, oil damped, adjustable spring preload at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by shaft - no chain or belt maintenance at all, though the drive-shaft oil should be changed on the manufacturer's interval.

Handling the weight at a standstill

At 408 kg, the Boulevard C109RT is a substantial machine - low-speed manoeuvring in car parks takes more physical effort than on a lighter bike, though the weight disappears once rolling.

Boulevard C109RT - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2009 Suzuki Boulevard C109RT, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained Boulevard C109RT should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any Boulevard C109RT. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Carburetor upkeep

Keep the carburetors clean and free of deposits. If the Boulevard C109RT has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
