Honda CRF450L / CRF450RL Performance Upgrades:
Off the showroom floor, the 2019+ Honda CRF450L/RL suffers from a few emissions-related fueling issues that hinder performance and ride-ability. Some of our customers complain about poor low RPM fueling, stalling, as well as a very snatchy on-off throttle response. Luckily there are a few things you can do that will make the bike run much better, give it more power/torque, and make it much easier to rider.
An aftermarket ECU (best option) or EFI Controller is the best way to get your CRF450L/RL to run properly, and also increase power and torque. We use the Vortex ECU on our CRF450L/RL Project Bikes...
Vortex X10 ECU
GET RX1 Pro ECU
JD Jetting Power Surge 6X EFI Controller
And to improve performance even more, save some weight, plus make the bike sound better, add an aftermarket exhaust system from the CRF450X...
CRF450X Yoshimura RS-4 Full Exhaust System
CRF450RL/L/X Graves Titanium Full Exhaust System
CRF450X Pro Circuit T-6 Titanium / Stainless Full Exhaust System
CRF450RL/L/X Graves AIS Block Off Kit
Additionally, the following products will incrementally make the bike run better, and help reduce stalling, and provide a smoother, more controlled and tractable power delivery on your 2019+ Honda CRF450L/RL...
Steahly Flywheel Weight
Twin Air Power Flow Filter Kit
Twin Air air filter
Doing these couple of things to the bike will make it run much better, help get rid of the snatchy throttle, and improve performance substantially compared to stock. It will also drop about 8-9 lbs in weight, plus the bike will obviously sound much better if you do an aftermarket exhaust system.
