CFMOTO 450SR-S (2024+) Maintenance Schedule and Service Info
This is the maintenance schedule and associated service intervals for the CFMOTO 450 SR-S. The following motorcycles share the same platform and engine:
- CFMOTO 450SR: faired entry-level sport bike
- CFMOTO 450SR S: updated version with higher-spec components
- CFMOTO 450NK: naked variant based on the same chassis and engine
The core engine architecture is identical across these models. It features dual balance shafts, a 6-speed transmission with a slipper clutch, and a chain final drive. While the 450SR S shares the same fundamental mechanical package as the base 450SR, it adds a single-sided swingarm, a larger rear brake disc (240 mm vs 220 mm), a revised underbelly exhaust system, electronic traction control, and updated electronics including automatic headlights and phone projection on the 5-inch TFT display.
Despite the updates on the 450SR S (such as a larger rear disc and different rear suspension), the core engine and chassis service requirements remain unchanged and can be treated identically for routine maintenance.
No changes to engine internals, valve service intervals, or major maintenance items were made between versions. However, due to the upgraded rear brake and suspension on the SR-S, servicing those specific components may involve slightly different procedures or tools. This does not affect service intervals.

CFMOTO 450SR-S (2024+) Service Intervals
The basic service interval for the CFMOTO 450SR-S is every 6,000 miles / 10,000 km or every 12 months, whichever comes first. A break-in service is also required at 600 miles / 1,000 km. Major service items include a valve clearance inspection at 24,000 mi / 40,000 km.
The 449cc parallel twin is accessible and designed with ease of service in mind. The single-cylinder head helps simplify valve inspections. Use good quality 10W-40 oil and replace worn parts early if riding in harsh conditions.
General Notes on Serviceability for the CFMOTO 450SR-S
- The 450SR-S uses a 449.5cc liquid-cooled parallel twin with a 270-degree crank and dual balancer shafts. It’s compact, smooth, and relatively easy to access for most service tasks.
- Oil changes are straightforward. The filter is side-mounted and the magnetic drain bolt is easy to reach. Always replace the crush washer and torque to spec.
- The valve clearance inspection at 24,000 miles / 40,000 km is a major job. The tank and fairings must come off, but the single-cylinder head and compact layout keep it manageable.
- The air filter housing sits under the tank and can trap moisture or oil. Clean or replace more often in dusty or wet conditions.
- Chain tension is adjusted via an eccentric hub on the single-sided swingarm. Use the correct tool and follow the manual to avoid misalignment or brake rotor damage.

About the 2024 CFMOTO 450SR-S
The CFMOTO 450SR-S is what happens when CFMOTO takes a solid entry-level sportbike and decides to give it the sharpest suit in the closet, plus a few extra tricks up its sleeve. Think of it as the full production realization of the earlier SR-C21 prototype, finally with the exotic flair and spec sheet to match the promise. It’s still built around the same lively 449.5cc parallel twin, but the SR-S throws in sharper looks, a few smart upgrades, and some well-judged refinements to make it more than just an aesthetic refresh.
Let’s talk engine. It’s the same 270-degree crank twin as the 450SR, pumping out a healthy 38 kW at 9,500 rpm and 40 Nm of torque at 7,750 rpm. That crank layout gives it the same kind of character you’d find in Yamaha’s R7 or MT-07, with a snappy response, plenty of low-end grunt, and a hint of that V-twin bark. Power is linear, the slipper clutch keeps things tidy on aggressive downshifts, and the six-speed box is slick and confidence-inspiring whether you’re slicing through traffic or leaned over chasing apexes.
The SR-S sets itself apart with a single-sided swingarm, which is rare in this price range, and it’s not just for show. It saves weight at the rear, showcases the rear wheel, and comes paired with a belly-mounted exhaust for a cleaner silhouette. Suspension is still handled by 37 mm upside-down forks and a preload-adjustable monoshock, but ride quality feels better dialed than the original. Braking is handled by a 320 mm disc up front with a four-piston caliper and a 220 mm disc at the rear, now with a twin-piston setup instead of the single-piston unit on the base SR.
It’s not just hardware that’s been upgraded. The electronics get an upgrade too, with traction control now standard, a five-inch curved TFT display with phone mirroring, automatic headlights, and even emergency brake lights. These are features you don’t often see at this price point.
The 450SR-S is a bit lighter too, dropping to 171 kg wet compared to the SR’s 179 kg. That makes it feel slightly sharper in transitions, and combined with the revised fairings and winglets, it definitely looks the part. Ergonomics remain unchanged, offering a committed riding position that’s sporty but not punishing, with a 795 mm seat height that’s manageable for most riders.
| Feature | CFMOTO 450SR-S | CFMOTO 450SR |
|---|---|---|
| Engine | 449.5cc parallel twin, 270° crank | Same |
| Power / Torque | 38 kW @ 9500 rpm / 40 Nm @ 7750 rpm | Same |
| Rear Swingarm | Single-sided swingarm | Standard double-sided swingarm |
| Rear Brake | 220 mm disc, twin-piston caliper | Same |
| Electronics | Traction control, automatic headlights, ESS | ABS only |
| Weight (Curb) | 171 kg | 179 kg |
| Seat Height | 795 mm | Same |
| Front Suspension | 37 mm USD forks (adjustable) | 37 mm USD forks |
| Rear Suspension | Adjustable monoshock | Monoshock |
| Brakes (Front) | 320 mm disc, radial four-piston caliper (Brembo M40) | Same |
| Tires | 110/70 R17 front, 150/60 R17 rear | Same |
| Fuel Tank Capacity | 14 L | Same |
Maintenance is straightforward. Oil changes and chain adjustments are easy, and valve clearance checks aren’t due until 24,000 miles / 40,000 km. Air filter and spark plug access are simple, and the bodywork is designed to come apart with minimal swearing. The single-cylinder head keeps major services from becoming a nightmare.
The 450SR-S is proof that CFMOTO is paying attention. They’ve taken a solid, stylish entry-level sportbike and added just enough edge, tech, and refinement to make it something special. If you’re looking for a small-displacement bike that punches well above its weight, this one deserves a long look.
