The 2015 Suzuki Boulevard M90 is also identified as the VZ1500. Suzuki’s published M90 specifications describe a 1,462 cc, liquid-cooled, fuel-injected V-twin with a five-speed transmission and shaft drive, but the manufacturer’s specification sheet is not year-stamped. Use it as M90-family reference data, then confirm year- and market-specific details against your motorcycle’s documents and VIN before ordering parts.
What is the 2015 Suzuki Boulevard M90?
The Boulevard M90 is a large-displacement cruiser in Suzuki’s M90 family, also known by the model designation VZ1500. Suzuki’s model-family sheet describes a 54-degree, four-stroke V-twin with overhead camshafts, liquid cooling, fuel injection and semi-dry-sump lubrication. It pairs the engine with a five-speed constant-mesh gearbox and shaft final drive. The sheet does not identify a model year, and Suzuki notes that specifications and equipment may vary by territory and change without notice. Suzuki M90 specifications.

Why you may see a different fuel-tank figure
Suzuki Motor of America’s US specification sheet for the adjacent 2016 model year lists a 4.76-gallon tank. That document is dated January 29, 2016; it is useful as adjacent-year US context, not proof of the 2015 capacity. Keep it separate from the M90 family sheet’s 18.5 L / 4.7 US gal figure.

Replacement tires: confirm size and rating
Suzuki’s M90 sheet gives a front size of 120/70ZR18M/C 59W and a rear size of 200/50ZR17M/C 75W, both tubeless. These dimensions are a starting point for a replacement search—not confirmation that every tire with those dimensions is suitable for every 2015 market version.
- Match the front and rear positions to the respective dimensions.
- Check the required load and speed ratings against the motorcycle’s manual and the tire manufacturer’s fitment guidance; Suzuki’s sheet lists 59W front and 75W rear.
- Confirm that the specific tire is approved for the wheel, motorcycle, and market. Do not assume a dimension-only match establishes fitment.
The adjacent-year 2016 US sheet lists the same tire dimensions, but the correct authority for an individual 2015 bike remains its documentation and exact market application.

How to check replacement-part fitment
Fuel tank and painted body parts
Oneida Suzuki’s M90 tank listing shows a white 2015 option, part number 44100-40H62-YWW, and a black option listed across 2013–15. The listing explicitly says it is not for California models. Paint color, market, and model identity all affect fitment; verify the VIN and OEM part number with the seller before ordering. Oneida Suzuki’s M90 fuel-tank listing.
Fuel-system parts
Partzilla has a 2015 Boulevard M90 VZ1500 fuel-pump diagram listing. A diagram listing can help identify the relevant assembly, but it does not by itself establish that a particular replacement part fits your bike. Confirm the part number against the VIN and the listing’s application details. Partzilla’s 2015 M90 VZ1500 fuel-pump diagram.

Owner’s manual, service manual and maintenance
Suzuki’s M90 specification sheet tells riders to read the owner’s manual carefully and follow scheduled maintenance. The sources available here do not establish the official 2015 maintenance intervals, so do not infer a service schedule from the model-family sheet or an unaffiliated manual listing. Use the owner’s manual for operating guidance and the applicable official service information for repair procedures and intervals.

No named, identifiable fuel-economy measurement for the 2015 M90 is established by these sources, so a reliable miles-per-gallon estimate or range cannot be given here. Suzuki’s 2016 sheet describes the engine as designed to provide “good fuel economy” but publishes no consumption figure. Actual range also depends on riding conditions and usable fuel, so calculate it from your own measured consumption rather than treating tank capacity as a range claim.
