Understanding the Suzuki Boulevard M109R BOSS
Before you reach for the toolbox, it’s important to know your bike. The M109R BOSS is a factory-tweaked version of the standard M109R, featuring special paint jobs, blacked-out trim, and a “bad-to-the-bone” attitude. But many owners take things even further with aftermarket products and custom builds.
Key Features:
– 1,783cc (109 cubic inch) V-twin engine
– Massive 240mm rear tire (stock)
– Aggressive, long-and-low cruiser styling
– Distinctive headlight cowl and drag-style handlebars
– Factory blacked-out engine and trim components
Why Custom Your M109R BOSS?
Personalizing your Boulevard can offer:
- Visual uniqueness—make your M109R BOSS stand out from the crowd.
- Enhanced performance—unlock sharper power delivery, snappier throttling, or better handling.
- Greater comfort—tailor your riding position and ergonomics.
- Improved sound and presence—give your machine the voice it deserves.
- Increased value—well-done customizations can maintain or increase resale value.
Popular Ways to Customize the M109R BOSS
1. Performance Upgrades
For many M109R owners, performance is king. You can boost the already-potent V-twin with these popular mods:
-
Aftermarket Exhaust Systems
Replace stock pipes for a deep, rumbling tone and some extra power. Brands like Roaring Toyz and other specialists offer high-quality options. Look for systems designed to match your style (shorties, 2-into-1, etc.). -
Air Intake and Filters
A high-flow air kit allows the engine to breathe better, improving overall efficiency and horsepower. -
Fuel Management Systems
When upgrading exhaust or intake, a fuel tuner ensures the air/fuel mixture is correct—safeguarding the engine and optimizing performance. -
Big Bore Kits
For the truly ambitious, increasing engine displacement via a big bore kit can result in significant power gains, but usually at higher costs and complexity.
Best Bang for the Buck Upgrades:
- Swapping to aftermarket exhaust and intake, combined with a fuel controller, offers noticeable power and sound gains for reasonable investment.
2. Aesthetic Customizations
The M109R BOSS is known for its bold looks, but customization can take this to the next level.
-
Custom Paint and Graphics
Unique paint schemes, stripes, ghost flames, or hydro-dipped graphics can transform your bike’s personality. Choose colors that highlight your style or complement the bike’s aggressive stance. -
Wheels and Tires
- Oversized Front/Rear Wheels: Upgrading to a 23” front wheel or a 300mm rear tire is a signature look. Wide tire kits require special swingarms and spacers—specialist shops like Roaring Toyz and Tricked Out Customs can help.
-
Custom Wheels: Machined alloy wheels or blacked-out rims enhance both looks and handling.
-
Bodywork Mods
- Extended Rear Fenders: Give your cruiser a meaner, tucked tail look.
- Custom Seats: Solo or two-up saddles in unique materials, with extra padding or custom stitching.
- Headlight/Fairing Upgrades: LED lighting, unique headlight nacelles, or windshields with integrated design.
3. Comfort and Ergonomics
Long rides call for adjustments in comfort:
- Handlebars: Swap the stock bars for pullback, drag, or ape-hanger styles to suit your posture.
- Foot Controls: Forward, mid, or adjustable controls allow for perfect leg stretch.
- Seat Upgrades: Custom gel or memory foam seats can make a world of difference on long rides.
- Suspension Mods: Adjustable shocks or lowering kits let you dial-in ride height and comfort.
4. Additional Functional Upgrades
Don’t overlook practical addons:
- Integrated LED Lighting: For better night visibility and a modern touch.
- Audio Systems/Speaker Pods: Pump up the tunes for those highway runs.
- Custom Mirrors and Levers: Small details, big impact.
- Wind Deflectors & Mini Fairings: For improved highway comfort.
Steps to Customizing Your M109R BOSS
Here’s a roadmap to help you plan and execute your customization journey:
-
Define Your Vision
Decide if your focus is appearance, performance, comfort, or a mix. Collect inspiration photos and lists of must-have features. -

- Look for seasonal discounts or used parts in good condition from reputable sources.
- If importing parts, calculate shipping and possible customs duties before buying.
- Some upgrades pay off in the long run (like better fuel efficiency with intake/exhaust), balancing initial costs.

Frequently Asked Questions (FAQs)
Can I install a wide rear tire (like a 300mm) on my M109R BOSS without modifying the swingarm?
No, installing a 300mm rear tire usually requires a wider custom swingarm and appropriate spacers. It’s a major modification best handled by specialists.
Will new exhaust or intake mods void my warranty?
Aftermarket exhaust and intake upgrades may affect the factory warranty, especially if they lead to engine or emissions-related issues. Always check with your dealer before proceeding.
What’s the most cost-effective performance upgrade available?
Swapping to a high-flow intake and aftermarket exhaust, paired with a fuel management system, offers great performance and sound gains for a reasonable price.
How difficult is it to change the handlebars or seat for added comfort?
Handlebar and seat swaps are among the more accessible mods. Most riders with basic mechanical knowledge can tackle them, though bar changes may require rerouting cables or brake lines.
Do all custom parts fit BOSS models, or do I need parts specific to the BOSS edition?
Most accessories and customs are compatible with all M109R versions, BOSS included. However, always double-check part specifications, especially for painted or color-matched components, as BOSS editions have unique finishes.
