Justin Brayton’s Factory HRC Honda CRF450R
Justin Brayton’s Honda CRF450R
In 2019 Justin Brayton became the oldest rider to acquire a Supercross Main Event at the age of 34 at Daytona,Florida. He was on a Motoconcepts/Smart Top Honda CRF450R that year and has now graduated to the HRC Factory group for 2020. This isn’t even Justin’s time with HRC but a well deserved one after a good performance this past year in Supercross. As it sits now, Chase Sexton will take over that seat at 2021 time. You can’t ignore the expression of the mill bike this year. In its center, this bicycle is easy and clean In the head to the graphics design. Mechanic Brent Duffe spent a while together with Travis Fant to examine the technical elements of what constitutes Justin’s bicycle a mill machine.
for Justin Brayton that he was on a Honda this past year and was able to take over a number of his preferred components. Including his Renthal 997 handlebars. He loves to roll them just a bit also.
Justin Brayton shaved down bicycle tube
Justin runs a shaved down Works Connection aluminum throttle tube. When Brent told us this we had to put our hands on it to determine how skinny it was. It turned out to be a significant difference from the stock version. His ARC brake lever is also quite close to the handlebar and incredibly easy to grab. Justin prefers a skinnier lever on either the clutch and brake aspect of the bike.
Justin likes to conduct a grip that is thinner . It is possible to view in the photo above that the grip is rolled forwards a pinch and the internal waffle is cut. This is designed around Bratyon’s tastes.
Justin Brayton Hydraulic Clutch
You’ll notice on the mill HRC hydraulic clutch master cylinder and brake master cylinder side you will find carbon protective bits over them. This bit of protection is on most of the bikes you ll find from the pits at the mill level. Believe it or not, a great deal of stones and debris even in Supercross get stuck at the bikes. Mechanics and the team wish to do the very best job possible to avert a rider. “Rocks will ruin races”, ” said Brent. Also a cool thing to say is that on either the clutch and brake side, the lines are fairly tucked away and close to the handlebars.
Front brake master cylinder and caliper on the brake system are HRC components. The line is a stock Honda CRF450R part.
One thing that stood out right away was Justin’s tall HRC bar mounts. Duffe has been with Justin for a while and traveled with him throughout his Australian Supercross season. Brent said that Justin likes to start the cockpit and has always preferred a front end. The steering is the HRC works component with a race indoors.
On the right side of the handlebars that you ’ll locate a start button made for your group in home. This isn’t exactly what comes to the 2020 Honda CRF450R in stock trim but serves the exact same function. This past year we learned that Honda changes the button onto the bars since the inventory version collects sand and may get jammed up at the event of the rider seeking to restart the bicycle. This start button Justin’s bike is also smaller in dimension and every little bit counts on your weight loss.
Auxiliary start switch
Almost every group has an start button on their bikes. Some more hidden than others. This has come to be the norm because most of the bikes in 2020 have no kick start. Although it’s nice for the rider to have a button, then it may also be troublesome if the match has been ruined during racing. Having a copy strapped to the frame provides the team a few insurance their rider comes with a means to get going again.
Justin has had a working connection with SHOWA suspension since 2016. From 2017 to now there were slight changes in the setting but Brent clarified to people that they haven’t done a whole lot. It makes it pleasant that the present version Honda hasn’t changed too drastically. Brayton and Duffe have raced this bike around the world so they feel as they have a very dialed set up around the Honda. This doesn’t mean that they aren’t receptive to testing, they do but Justin sticks to what’s comfortable for him. You are also able to get a good watch on the HRC bottom clamps that the team is running on his bicycle.
Justin is present about a Works Connection holeshot button. Some groups run a double button based on the monitor conditions but that set up is a one size fits all. Brent told us that the button is really deep into the front fork and with the suspension being stiff, he has to have a 2nd man help him on the line to place the holeshot apparatus in place before remove.
Have a look at the attachments on Justin’s fork defenses. Every small bit of the bike is set up for racing. The axle is a inventory steel element. The group has options to run titanium should they wish to but Justin actually doesn’t have a preference like a number of those riders do in this department. The lugs did look oversized but there are some things Honda likes to keep hush hush on. That’s the fun in doing these tales! You also get a great look at the works Honda hub inside this picture.
In this photo you may observe the DID Dirt Star rims with works spokes, beefed up nipples, and works hub. The wheels take a complete beating in Supercross so that they need to be powerful to make it through the day. Wrapped round the wheels would be Spec Dunlop tires. Most likely this is a scooter which will find its way into the general consumers hand at a certain point when it makes the cut. You can even find the works carbon front rotor guard employed for protection.
An up close look at the mill Yutaka front rotors on Justin Brayton’s 450. While the rotor might be Yutaka, the size doesn’t change from the inventory 2020 Honda CRF450R version.
Brent Duffe advised Dirt Bike Magazine that the front brake is very powerful. The pistons will be the exact same size as the manufacturing version. You can even find the HRC brake hangar attached to the forks. Safety wire of course is inserted to this brake line for insurance and also the Nissin caliper is glistening up for that mill feel.
Twin Air radiator works and covers radiators
The group runs works radiators in the left and the right of this bike. The size isn’t different from inventory but they are strengthened from the group for racing. The Twin Air screens you see over the radiators stop from sand packing inside and causing the bike to heat. This also protects the drains out of stones or debris hitting that area of the bike.
Data antenna radiators
A data logger sits behind the abandoned shroud on Justin’s Honda. The antenna shown this was an interesting piece while blowing off the bike, we discovered. Data acquisition is a large part of the mill team attempts. Honda was tight lipped on what data.
Away from the right radiator it’s possible to observe the down stem is just a single apparatus. On the inventory Honda CRF450R you will find just two. This can be really for weight savings. You can even understand the titanium spicket inside this picture.
Justin Brayton’s Factory HRC Engine
Here’s a look at the ceramic spicket coming from the water pump cover. The inventory unit has been pressed in while those are bolted on instead. This is just another security measure for your team to get for racing purposes.
You’re able to observe the engine mounts inside this picture. The HRC runs stocks engine mounts around on the bike. Titanium bolts and aluminum nuts are utilized to finish it all off. The inventory mounts have proved to the riders that other choices that are available don’t fit their requirements. You will see carbon and titanium if you look closely enough.
The stock radiator cap onto the Honda CRF450R is a 1.1. The Factory group utilizes a 1.8 cap instead for higher boil over endurance.
Hinson clutches are utilized at the Factory HRC Honda. It’s a 1 plate clutch. That is a milder set up than he has run in the past. Justin conducted a Rekluse about the MotoConcepts staff. We do know from talking to the MCR team that Justin had the stiffest clutch spring set up on that group in that time period of any of these riders.
The first thing you see is. The side cover is a works part. It is ceramic coated for durability and heat dispersion. This is one of several engines that stay in rotation.
Yoshimura exhaust front to back is connected to Justin’s Honda. You’re able to observe the O2 sensor onto the header that is incorporated into the data charging system. Both Kenny and Justin are running identical systems.
It is possible to see that the extra skin around the Yoshimura header. This is protection for your header in the event of an accident or debris hitting on .
It is a works HRC brake pedal from Japan. It’s the standard form, length, and height of this 2020 Honda CRF450R. There’s a ceramic brake tip at the end using a slightly different adjusting point onto it. You can even find the brake snake attached to this brake suggestion. This keeps tuff blocks things becoming trapped behind the brake pedal during the race. Sometimes something will get trapped inside the pocket behind the even or pedal and cause the brakes to drag smoke.
Justin Brayton’s back brake assembly
Another item used on the Honda is just above the back brake pedal spring. This threaded bit extending through the arm will help stop the back brake from getting up or bent forwards during racing. This is also a works HRC cleavace going into the mastery cylinder.
Side view of this threaded bit that helps prevent the brake from becoming pushed. Above the back brake spring.
This is a mill back brake master cylinder. The only distinction is that it doesn’t have a sight window at the back of it. Before the gap is cut in for the mill teams to utilize the master strands are pulled off the assembly line. This prevents any damage to the glass causing the back brake to get rid of fluid on race day. Again safety wire for insurance purposes. An inventory swing arm pivot can be used (right side of picture ) with a aluminum nut on the end of it. Titanium will be used by some groups rather than the inventory unit.
Two things stick out in this picture. 1 is that the carbon sticking out a pinch from behind the air box. That is the carbon starter relay mount that HRC Honda adds for their bikes. This provides more clearance for the shock body to it also re-positions the relay. Two might be the small gap between the subframe and primary frame. That is a cut subframe.
The whole linkage system about the HRC Honda CRF450R is a works bit. The measurements are identical to what you will discover on inventory.
The Works Showa rear shock of the HRC team. While the parts have changed a bit the settings aren’t much different over the past few decades for Justin. Brent told us that Justin will race his set up all around the world with how dialed he has it. They want to make adjustments and never do anything drastic.
Factory Honda back brake assembly
Just like the front of the bike, Justin comes with a brake line. The whole system is basically stock. A works standard sized Yutaka Cable is utilized back.
The axle is a inventory element. The Axle cubes are HRC Japan with ceramic adjusters.
A mill HRC bit is your chain guide. Because the holes have been removed this chain guide differs from the inventory. This helps prevent from mud packing in. We have seen groups run lengths to the guide to keep the series and not jump off course.
Chain and sprockets are used on Justin Brayton’s Factory Honda. Since Justin has changed to the team he has gone a tooth from the back. They generally don’t change that gear mix (13/48) hence the back wheel is at the identical exact place every race. Whatever gearing the group runs that locks them in on swing arm spans. A DID O-ring series is used for durability functions. Brent stated not and he can place the chain need to fix it later. It’s a very dependable part on Justin’s bike.
The flip side of this bike. A works transmission does run. You are able to get a great look at the red valve cover the group added.
A Twin Air filter can be used and also you also ’ll detect the light weight aluminum screw that fastens down it for weight savings.
A basic to the Factory Honda attempt will be the ceramic foot barrels containing ti pins and mounts. The position of the foot peg itself hasn’t really been changed at all.
Justin runs a ceramic HRC shifter using aluminum tip onto it. The situation is at the inventory setting. It is possible to see numbers like the one on the shifter. All these are for stock purposes. This keeps tabs on what parts go when and where there’s a problem, they can reference back to this amount specified.
A stock skid plate is used by the group. Something pretty cool we heard is that Honda uses the 450X skid plate since it doesn’t need holes in it and helps prevent from sand packing to the engine area.
Justin runs a stock seat with Throttle Jockey seat cover. Justin prefers to have a broken in seat rather than have that feeling that is stiff while he is on the bike.
Aside from the front/rear suspension and suspension set up Ken Roczen’s and Justin Brayton’s bikes aren’t quite different. Justin doesn’t operate traction tape on the frame while Kenny does.
Justin Brayton’s bike is topped off with an all new graphics design from Throttle Jockey. They have worked in keeping the material light weight rather than using additional material in places it’s not required.
