Riders frequently want to speed up the Raptor 90 as they gain expertise and confidence. This article discusses how to safely and effectively increase the Yamaha Raptor 90’s speed, making it more exhilarating while keeping its safety features.
Yamaha Raptor 90 Tops Speed
A 90 cc single-cylinder engine and fully automated CVT gearbox power the Yamaha Raptor. Its peak speed is 30 mph, although it can travel 15-18 mph. Due to its two speed limiters, it will require some changes.
Increase Yamaha Raptor 90 Speed?
Safe and fun, the Yamaha Raptor 90 is ideal for young ATV enthusiasts. One safety feature is its speed limiter, which limits vehicle speed. The Raptor 90’s speed limitation may be adjusted to fit young riders’ skills and confidence. The text details how to properly modify the Yamaha Raptor 90 speed restriction.
Adjust The Speed Limiter Features
Yamaha Raptor 90 Top Speed is kept within a sensible range, typically between fifteen and eighteen miles per hour, via an integrated speed control.
Beginner ATV riders’ safety is paramount, making this choice important.

Throttle Limiter
The maximum speed of an ATV can be controlled by a mechanical device called a throttle limiter. It limits the amount of throttle that can be applied. Parents or guardians may set a maximum speed that is appropriate for the rider’s aptitude, which is particularly crucial for junior ATVs like the Raptor 90.
Adjusting the Throttle Limiter
- Locate the Limiter: Find the throttle limiter on your Raptor 90. It usually looks like a screw or bolt on the throttle control.
- Make Adjustments: Use a suitable tool (like a wrench or screwdriver, depending on the limiter’s design) to adjust the limiter. Tightening it will restrict the throttle more, reducing speed. Loosening it allows for more throttle and higher speed.
- Test the Adjustment: After adjusting, test the ATV in a controlled environment. It’s important to check that the new setting is suitable for the rider’s skill level.
- Fine-Tuning: You might need to repeat the adjustment process a few times to find the perfect balance between safety and performance.
Safety Precautions
- Adjustments: Make small adjustments to avoid sudden increases in speed that the rider might not be able to handle.
- Monitoring: Continuously monitor the rider’s ability and readiness for higher speeds.
- Safety Gear: Always ensure that the rider is wearing appropriate safety gear, including a helmet, gloves, and protective clothing.
- Adherence to Regulations: Be aware of and adhere to any local regulations regarding ATV use and modifications.
Engine Speed Limiter Plate
Finally, to control the engine’s power and maximum RPMs, we obtained an engine speed limiter plate. The plastic CDI Box seat incorporates the engine speed restriction plate. The engine’s maximum RPM is 4900 by default, but after you remove it, you may increase it to 8500, which will result in double the acceleration and top speed. The limiter plate is secured in place by two screws; to remove it, just loosen them and pull the plate off.
However, until you’re comfortable with the quad-core, I suggest that young riders ease off on the throttle limiter screw. When you’re confident in your abilities, you may increase the machine’s speed and power by retightening the throttle restriction, which you can then gradually release again.
