This is the maintenance schedule and associated service intervals for the Suzuki Boulevard M50, also known as the Suzuki Intruder M800. Suzuki based the Boulevard M50 on the same 805cc motor as the one used in the Suzuki Boulevard C50.
The 2005+ Suzuki Boulevard M50 uses an 805cc 45-degree V-twin that’s liquid cooled, fuel-injected, and drives the rear wheel through a five-speed transmission and a shaft drive. It’s thus the smallest of the Boulevard line — the baby sibling of the M109R, and the smaller sibling of the M90 too.
The Boulevard M50 or Intruder M800 is a middleweight V-twin cruiser, made from 2005 originally, but significantly visually updated in 2010, and then again in 2015 when it started blacking things out (but without ever using the B.O.S.S. branding like on other Suzuki cruisers. You can check out the gallery below for an evolution of the Suzuki Boulevard M50 and how it changed visually over the years.
Even though the Boulevard M50 changed in style (and got a lot better looking, honestly), the basic maintenance for the M50 has stayed the same over the years (although the air filter setup changed in 2009). Just change the oil, coolant, brake fluid, gear oil (for the shaft drive) and spark plugs every now and then and you’re golden.

About the Suzuki Boulevard M50
The Suzuki Boulevard M50 is Suzuki’s entry-level V-twin cruiser (well, apart from the one in the “learner” categories.
The M50 uses an 805cc V-twin that makes a very modest 39 kW (52hp) at 6,000 rpm, with maximum torque of 69 Nm (51 lb-ft) @ 3,200 rpm. This makes it no slouch — it’s roughly equivalent to a Triumph Scrambler, which means you can get some decent torque action out of it if you’re generous with the throttle. You should even be able to spin the wheel with ease.
The engine does more than simply push the bike forward, though. Suzuki has struck a careful balance with its modest 45-degree V-twin. It’s classic-looking, stylish with its blacked out treatment (on those that have it, anyway), and has plenty of character.
The Boulevard M50 is no lightweight, of course. Fully fuelled and ready to go, it weighs 269 kg (593 lb).
Suzuki doesn’t go for the top-shelf gadgetry for this ride, but that doesn’t mean it’s completely devoid of tech. Suzuki gave it idle speed control, allowing for choke-free cold starts, as well as an ECM that drives dual throttle valves.
Most interestingly, Suzuki opted for an inverted fork for the M50. This makes it the only middleweight cruiser with an inverted fork. Unique!
