On the whole, yes—the CRF50 family includes a throttle limiter to cap throttle input for beginner riders, though the exact presence and method can vary by model year and market. In practice, many owners discover a removable limiter clip or a carb stop that restricts full throttle.
What is a throttle limiter on the CRF50?
A throttle limiter is a physical restriction that prevents the twist-grip from opening the carburetor beyond a set angle or travel. On most CRF50 variants, the limiter is implemented as a small stop or clip in the throttle mechanism or near the carburetor’s throttle stop, and in some cases as a removable spacer or adjustable screw.
How it is implemented
The exact hardware can vary by year and market. Some bikes use a removable limiter clip near the handlebar, others rely on a small screw or spacer on the carb’s throttle stop. In some cases, the limiter is integrated into the throttle housing and requires disassembly to adjust.
Model-year and market differences
The exact setup varies by year and region. Some CRF50s arrive with an obvious limiter in place for beginner riders, while newer or different-market units may use alternative methods or omit an external limiter entirely. The limiter is typically aimed at capping the top-end speed to keep the bike controllable for young riders and to comply with safety standards or rider-education programs.
Below is a quick snapshot to help identify limiter presence by era. Note that specifics can differ even within families based on regional regulations and dealership practices.
- Early CRF50F and CRF50R models (roughly pre-2015 in many markets): common to include a visible throttle limiter device; sometimes a removable clip or screw on the throttle stop.
- Recent CRF50F models (2016–present in many regions): often retain a limiter, but the exact implementation may shift to a less obvious stop; some bikes ship with the limiter pre-installed and a documented removal procedure in the owner’s manual.
- Market variance: some countries require strict rider training or speed caps, leading to stronger emphasis on limiter presence and safety features; in others, the limiter is optional or replaced with different restrictions.
In practice, if you’re shopping for a CRF50 and want to know whether the throttle limiter is installed, check the throttle grip and the carburetor’s throttle stop area or consult the manual or a Honda dealer. If in doubt, a quick inspection can reveal the presence of a limiter or its absence.
How to check and adjust safely
If you’re planning to check or adjust the throttle limiter, follow these steps carefully to avoid damaging the bike or violating safety rules.
- Inspect the throttle grip and housing for a small plug, clip, or spacer that prevents full twist; identify whether any such piece is removable or adjustable.
- Locate the throttle stop near the carburetor; look for a small screw or tab that physically limits the throttle opening.
- Consult the owner’s manual or a Honda service bulletin for the correct procedure to adjust or remove the limiter; some bikes require removing a small washer, clip, or spacer, not altering the throttle assembly itself.
- If removing or adjusting the limiter, re-torque any screws to factory specifications and test the throttle travel in a safe, controlled environment.
- Recheck throttle response and ensure the bike remains within the rider’s skill level; never operate a restricted bike at high speed on public roads or trails unless legal and safe.
The safety and warranty implications of altering throttle restriction should be considered. If in doubt, consult a certified mechanic or Honda dealer before making changes.
Summary
Bottom line: the CRF50 typically features a throttle limiter aimed at making the bike kid-friendly and controllable. The exact implementation varies by model year and market, and in some cases the limiter is removable, while in others it may be more integrated. Always verify presence, follow official guidance for adjustments, and prioritize rider safety and legal requirements.
How fast does a CRF 450F go?
Generally, a stock Honda CRF450R can reach top speeds of around 56-60 mph (90-97 km/h).
What does a throttle limiter do?
Throttle speed limiters control how fast the vehicle can go. Use a mini screwdriver to adjust the top speed of a throttle. Top speed can be adjusted from 5-100% and anywhere in between. Easy to install - simply plug this speed limiter in between the throttle and controller.
What is the top speed of a CRF50?
Here's a general breakdown of top speeds for popular 50cc models: KTM 50 SX (2-stroke): ~65 km/h (40 mph) Yamaha PW50 (2-stroke): ~45–50 km/h (28–31 mph) Honda CRF50F (4-stroke): ~40–48 km/h (25–30 mph)
