AMA RULE OF THE WEEK: WHICH BIKES ARE LEGAL AND WHICH AREN’T
In order for a bike to be legal to be raced in AMA Supercross or the AMA Nationals, the bike must be homologated—which means that the manufacturers have to submit proof that the bike is produced in sufficient numbers (400) along with a selection of production parts (to be used to compare to any part pulled from a race bike in a teardown). Not that an illegal bike would ever get torn down—unless the rider was a privateer or French. Oh yeah, the manufacturers also have to send a check to the AMA for several thousand dollars to get a bike on the list. Once on the list, a bike is good for five years before it has to be homologated again. Additionally, no bike older than 5 years old is allowed to race an AMA Pro race (which means that a 2014 model is illegal during the 2019 season).
Where the list gets tricky is when a manufacturer has to pony up for a bike that might not be raced by anyone—or typically by only one rider. For example, the Husqvarna TC125 two-stroke has been paid for and homologated so that Gared Steinke could race it in the 2016 Nationals. Note that Yamaha has not homologated any of their two-strokes, while Husky and KTM have paid for both of their 125 and 250 two-strokes.
If you are wondering where TM is, they don’t import 400 of any given model—thus they do not meet the AMA requirements.
We are kind of confused as to why any 250cc bikes are legal in the 450 class in Supercross. The last bike that Cooper Webb would want to come up to lap over a triple is a guy on a bike with 20% less power. This must be one of the AMA’s infamous “Good Buddy Rules” that the AMA wrote for the Supercross promoters as a hedge against not enough 450s showing up at a given race (and then they could throw a couple 250 guys in to make the gates look full)—or it is for the privateer who doesn’t have a 450 to race. The 250s should not be allowed in the 450 Supercross class—for safety reasons.

TAKE A LAP OF SATURDAY’S 2019 SEATTLE SUPERCROSS TRACK
MXA TEAM TESTED: TWIN AIR ICE FLOW RADIATOR CAP
Twin Air’s Ice Flow radiator cap increases the boiling point of the water in your bike’s radiator by increasing the amount of pressure inside the radiator. The difference between a stock radiator cap and a high-pressure one is dramatic. A motorcycle’s radiator cap is similar to the safety valve found on a chef’s pressure cooker. Since the boiling point of water increases when the water is placed under pressure, a radiator cap has a coil spring situated between two rubber seals. The stiffness of the spring determines how much pressure the water is under. As the water heats up, it expands. This expansion puts pressure on the radiator cap’s spring. When the radiator’s internal pressure exceeds the spring rate of the radiator cap, the hot coolant escapes and overflows between the two rubber seals. But, until the spring’s tension is overcome, the water will not boil.
Without any pressure on it, water will boil at 212 degrees Fahrenheit (at standard temperature and barometric pressure); however, a cooling system that is under 15 pounds of pressure will allow straight water to reach 250 degrees before it boils. For every pound of pressure exerted on the coolant, the static boiling point is raised by 3 degrees.(3) Measurement. There are many measurements of pressure. Most radiators use kilograms per centimeter squared (kg/cm2). American cars use pounds per square inch (psi). Scientists use kilopascals (kPa) and Europeans use barometric pressure (bar).
Most Japanese bikes come with 1.1 kg/mm2 radiator caps, while KTMs and Huskys come with 1.8 kg/mm2 caps. A 1.1 kg/mm2 cap can handle 14.22 psi before the coolant pushes the valve open and steam comes out the overflow. By increasing the radiator cap to 1.8 kg/mm2, the radiator can handle 25.6 psi, while a 2.0 kg/mm2 cap ups the ante to 28.45 pounds. The higher the pressure, the longer the water in your radiator will resist boiling.
Twin Air offers 1.8 radiator caps to replace the stock 1.1 caps on Hondas, Yamahas, Kawasakis and Suzukis. For KTMs and Husqvarnas, which come stock with 1.8 caps, they have a 2.0 cap, which is 176 kPa, 1.96 bar and 28.45 psi.
DIGITS: $24.95— www.twinair.com or your local dealer.
MXA RATING: Water cools the delicate internals of your expensive engine. If the water boils, you will have an expensive aluminum doorstop on your hands. Luckily, there are simple spring-loaded devices that can stop your bike from puking.
