Privateer stand out rider Henry Miller has been turning heads this 2017 Outdoor Motocross season and really making a name for himself in the ultra competitive 450 class. Henry has consistently ran down some top level factory riders and has also been a main stay in the top 10. Those in the know understand what a major achievement this is for a privateer like Henry due to the overwhelming amount of support, parts, and endless resources that the factory teams have. These highly supported teams often boasts race machines that perform at the absolute limit of modern technology, costing upwards of $100,000-150,000. These race bikes have very unique parts that are not attainable for people outside of the team. To put that into perspective the average privateer's bike costs around $10,000 and they are limited to off the shelf parts that any everyday customer can obtain.
There is a massive disconnect between the factory teams and the smaller privateer efforts. Everyone involved in the sport is aware of how much better the factory equipment is than the regular parts that a lot of the privateer riders have on their bikes. This equals out to less engine power, less responsiveness out of the machine, and inferior handling characteristics. Many privateers are lucky to reach the top 20 with privateer bikes. This is where Henry Miller and the Triggr Racing comes in. They have figured out a successful formula for dueling head to head with the factory riders and teams and continue to come out victorious in the end. Many riders and teams have commented on how competitive, fast, and reliable Henry is this summer and many marvel at this unique and very fast Yamaha YZ450F. Master tuner Chas Kadlec, Henry's mechanic, is the man behind Henry's great finishes and sweet race bike. We caught up with Chas to get an inside look at Henry's bike and see exactly what they do to stay in front of some of these factory teams...
"Starting from the top we use Cycra power flow plastic for improved cooling. We will actually cut the radiator shrouds a bit behind the radiator from the bottom straight up to the first brace. We do this to get the heat out and away from the radiators. We also use Mototape frame grip tape. This helps Henry really get a great grip on the bike in loose or rough conditions. We also run grip tape on the subframe where his boots would rub. Henry rides on the balls of his feet (which is good) so on the swingarm he will actually wear through the swingarm sticker by the end of the day from gripping the bike so hard."
"We also use custom seat covers and extra stiff foam from Seat Concepts. This works well for Henry and he really likes the grip and finish of the seats. Henry typically prefers new seat covers quite frequently because for him they have the best grip when new. He also prefers extra stiff seat foam."
"For the controls we run Odi podium McGrath bend bars with Odi medium compound half waffle grips. These grips have a great durable design and give Henry the feel he is looking for. For levers we use Arc unbreakable clutch and brake levers. We run the composite clutch lever and metal brake lever. Henry tends to run the levers in a more neutral position just a little bit below the bars. This can vary from rider to rider and most are particular about the placement of the levers."
"Moving downward the handlebars are mounted to Xtrig adjustable triple clamps. Ours are set to 22mm of offset for outdoors. These clamps compliment the bars, because the clamps have built in dampers and the bars actually have flex built into them via the crossbar. This creates a controlled level of flex and compliance through the front end for Henry."
"As for the chassis the frame is cut where the radiators are bolted approximately 8mm to narrow the bike up as much as possible. Combined with cutting the frame and the cycra plastic the bike is about 1 1/2 - 1 3/4" narrower at the shroud location. This is a critical fix and can greatly improve the controlled feel of the bike. The subframe has also been lowered 10mm so the seat doesn't kick him in the butt through the whoops and rollers. This was done by Clayton at Trick Engineering."
"As we all know the front brake on a bike is critical. This is even more important for fast pros like Henry. They require massive amounts of stopping power since the carry so much more speed than the average rider. We use a front brake setup built by Motostuff for some much needed stopping power which includes a Honda master cylinder, Motostuff pro lite brake line, Motostuff works billet caliper, Motostuff 280mm oversized rotor, and AP racing brake pads. All of this combined gives Henry the bite he needs when slowing down on the track. This setup is available to anyone through Motostuff. We always tell fans to beware though, because this setup will send you over the bars in a hurry!!! This is the best front brake setup in the business!! Henry actually prefers the brake lever a little "soft" feeling so that he has more modulation in the brake to prevent going over the bars on accident."
"Continuing downwards the wheels feature some really cool looking red Kite hubs and oversized spokes and nipples from Nore Worx. We wrap this with an Excel a60 rim, front and rear, along with Motostuff rear and front brake rotors. The final drive system consists of a Mika metals sprocket set up with a 13-50 gearing and a slick RK racing chain. Lastly Dunlop tires (usually mx3s) are fitted to the wheels to round out the package."
"For the real meat and potatoes part lets take a look at the motor. We use a full Hinson clutch setup for durability and feel. We also use a Carillo connecting rod for added reliability. On top of that have the folks at JE supply us with a high compression piston to get some extra power out of the Yamaha. Moving upwards in the engine we have a set of Pro Circuit cams to compliment the JE piston. To most people's surprise we have no porting or polishing. With these mods the bike would be way too hard to hang onto."
"Continuing on we have a GYTR ignition cover for durability and protection against rocks or big crashes. A Vortex ignition and VP Pro 6 high temp fuel are used to liven up the bike. Again, most don't believe me when I say it, but this bike has absolutely NO launch control or computers to aide/help with starts. The start at the Spring Creek National second moto was all Henry!!! Really cool huh?! We don't have a laptop to check the engine every time it comes off of the track like factory teams so we have to do the very best we can. Donnie over at FMF helped us on staying competitive with a 4.1 complete pipe. This is one sick exhaust and works well with the aftermarket engine components."
"Moving over the everyone's favorite part..... the graphics! We chose a unique design that highlights one of our biggest sponsors, FXR Racing. These graphics are done by Black Diamond MX. We get a lot of compliments and comments on the bike at each round. Underneath we have a very durable Cycra skidplate for protection against rocks. Continuing on with Henry's need for extreme grip and control we use Raptor titanium footpegs. Moving a bit forward slightly Henry likes to run the shift lever even with the top of the pegs. This is a bit different from the way the bikes are built in the factories."
"Let's talk suspension or arguably the most important part of the bike. The suspension that we use on the big Yamaha is the KYB air A-kit forks (upper level equipment) from Technical Touch. We pair that with a KYB A-kit shock also from Technical Touch, but setup by Ross at Enzo racing. Henry prefers air forks over the spring fork as this allows him to "change" the spring rate based on track conditions by raising or lowering the air pressure. The quick adjustability usually makes things better for me in the long run."
'One unique part of Henry's bike is the chassis. It really stands out from the other bikes on the line. The frame, swingarm and subframe are powder coated black for a really cool and trick look. Inside the frame we use a DT1 air filter with the Power Flow kit that has no metal screen on the air filter cage. This gives us a better flowing engine while still maintaining the needed filtration."
"Luckily for me Henry is not very picky on anything really. He is also consistent with his set up for the most part. Some small things I do to make sure we are good to go on the weekends is to check that the shifter is level with the peg and that the brake pedal sits a little bit higher than peg on the right side. Henry definitely uses the clutch when he's out there so I always check to make sure the adjuster isn't wore out or doesn't need replacing. We want to minimize any chances of part failure during these brutally long motos.
"Henry's an incredible rider and is great to work with. I think you could put henry on any bike and he could fly within an hour or two of riding it. He's got a lot of natural talent and can feel right at home very quickly. A great attribute about our dynamic is that he's not very picky so this allows us to test new things and find settings that work best. I strive to keep this bike performing at it's best each time Henry throws his leg over and I am glad we are starting to see that hard work pay off."
