Overview

The Suzuki Boulevard M109R B.O.S.S. is a cruiser produced from 2014 to 2024. The 2024 model has a liquid-cooled 1,783 cm³ V-Twin making 125 hp (93 kW) at 6,200 rpm and 160 Nm at 3,200 rpm, with a wet weight of 347 kg.

That torque arrives at relatively low engine speed, giving the large V-Twin its pulling force without needing to reach peak power. The 705 mm seat height makes footing easier for many riders, while the 347 kg wet weight can make low-speed maneuvering demanding; shaft drive also means there is no chain to clean or adjust.

Pros and cons

Advantages

Strong low-rev torque
Its 160 Nm at 3,200 rpm gives the V-Twin substantial pulling force at low engine speeds.
Low seat
A 705 mm seat height can make it easier to get both feet down at a stop.
Shaft drive
The shaft final drive avoids routine chain cleaning and adjustment.

Things to consider

Heavy at low speed
At 347 kg wet, the bike can take effort to maneuver in tight spaces or when moving it by hand.
Limited ground clearance
Its 130 mm ground clearance can leave less room over tall bumps and steep driveway transitions.

You should have a stable stance at a stop, although seat width and suspension setup still matter.
