Inside Look At A Factory JCR Honda CRF450RX

Factory bikes are always drool worthy as they look pretty, usually grace some unattainable parts, and flat out just have a cool factor that can’t be found on your average Joe’s bike. We’d say Ryan Surratt’s JCR Honda, a 2023 CRF450RX, fits right in this category coming off a round one win in the AMA NGPC Series and holding the points lead at round two of the championship. Without further adieu, let’s dive in to what makes this CRF450RX special and capable of beating the best off-road racers in the country with the right rider aboard.

A thing of beauty. As they have for nearly two decades now, Pro Circuit handles the suspension tuning for the JCR squad.
As of late, the JCR riders have been on A-Kit Showa equipment, but they are between sets right now and currently riding on stock components.

Like the front, a stock shock is temporarily in place.
The team is running a Pro Circuit linkage system, though it’s still in the development phase and missing the usual PC bling factory. The complete linkage has been a big step up in handling for the JCR riders and they are quite pleased with it.

Works Chassis Labs supplies the engine mounts for JCR and is credited with increasing chassis comfort for Surratt.

XTRIG ROCS triple clamps hold the front end together and are another key factor in increasing chassis comfort.

XTRIG PHDS Bar Mounts paired with a Renthal Fat Bar and a Scotts Steering Stabilizer finish out the cockpit.
The motor internals, aside from a Hinson Clutch, are completely stock including the ECU and mapping.
No carbon tip for a more durable product.

It’s all in the details…

The ARC hydraulic clutch master cylinder is said to improve the feel and engagement of the Honda clutch.

This velcro piece is there to add cushion against the triple clamps hitting the tank when whipping. Surratt may be racing off-road, but that doesn’t stop him from throwing down from time to time.
The team runs 13/49 gearing using Renthal sprockets and a DID chain.

The stock front brake lever provides a postive feel and really good braking power.

IMS Core MX sharp tooth footpegs are mean but grip well.

Pirelli tires and mousses are new for 2023. The team is very happy with the performance both in the desert and in the GPs. The MX32 Mid/Soft is the tire of choice for GPs and they actually run a fron tire developed by Johnny in the 90’s when racing in the desert.

The Twin Air louver covers keep mud and rocks out of the radiators.
Simple but effective.
