4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Unleashed in 2006 (VZR1800 / Intruder M1800R) with massive 112 mm pistons, GSX-R radial brakes, inverted forks, and a 240-section rear tire, continuing today in blacked-out B.O.S.S. trim.
Oil & Clutch Mechanical Engineering Note
Built with a low-profile semi-dry sump featuring TWO engine drain bolts; drain both plugs completely before refilling 3.6 L of SAE 10W-40 JASO MA2 with filter HF138, and check level via dipstick.
Garage Wrenching Gotchas
- Missing the second sump drain bolt leaves ~1 L of old oil trapped and causes massive overfilling; check warm oil upright with the dipstick resting unscrewed.
- Spinning two 112 mm pistons demands full cranking amps from the high-output YTX20CH-BS battery—keep it on an AGM maintainer during storage to protect the starter sprag clutch.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the Suzuki Boulevard M109R (2006–Present) require?
Because its wet multi-plate clutch shares engine oil with the gearbox, run SAE 10W-40 (JASO MA2) at 3.4 L (3.59 US qt) drain-only and 3.6 L (3.80 US qt) with filter (16510-07J00 / HF138 (M20×1.0 Fine Thread)). Also service final drive 220 ml.
How do you accurately check the oil level on the Boulevard M109R, and what are its service intervals?
Hold the bike upright on level ground 2–3 minutes after shutdown, wipe the dipstick, and rest it on the filler threads without screwing it in (threading it in reads artificially high and risks oil starvation). Torque the drain plug to 23 N·m with a new crush washer. Factory oil change intervals are every 6,000 km, with valve clearance inspection every 24,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the Boulevard M109R?
Fitted with 130/70 R18 M/C 63V front and 240/40 VR18 M/C (79V) rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 36 / 42 PSI (250/290 kPa) solo or 36 / 42 PSI loaded. Seat height is 705 mm (27.8 in) at 347 kg wet weight, delivering ~283 km per 19.5 L tank.
