This is the scheduled maintenance table and service intervals for the Suzuki M109R.
The Suzuki M109R has many names, from the VZR1800 through to the Suzuki Intruder M1800R.
It’s a huge, stomper of a muscle cruiser, with dyno tests showing 120hp at the rear wheel — massive for a cruiser.
Suzuki M109R Maintenance Schedule
The chart below lists the recommended intervals for all the required periodic service work necessary to keep the motorcycle operating at peak performance and economy. Mileages are expressed in terms of kilometers, miles, and time for your convenience.
You might have to service your M109R more frequently if you use it under severe conditions.
Valve clearance inspection/adjustment is every 24,000 kms or 14,500 miles. That’s quite generous!

General information about the Suzuki M109R
The M109R is a massive motorcycle.
It has a 1789cc engine, which is 109 cubic inches – hence the name.
They were fuel-injected and water-cooled from inception at 2006. They always pushed through a shaft drive, like many cruisers, making them relatively low-maintenance.
The engine produces 92 kW (123hp), and it has been dyno-tested to be very close to that. More importantly it puts out a huge 160 Nm (118 lb-ft) of torque, necessary to pull around the 346 kG/765 lbs of weight.
Even though it’s hugely powerful, the M109R is easy to ride and non-intimidating — even for a “muscle” cruiser.
Over the years, the model changed but not in any fundamental way. The main things that changed are wheels, conformity to emissions regulations (different exhaust and oxygen sensors), the clutch control, the headlight assembly… nothing core to the scheduled service.
The B.O.S.S. editions were also aesthetic updates.
