PRODUCT SPOTLIGHT: LIQUID A KIT
Press Release: Click Suspension was founded by Mike Marquez, a suspension developer, patent recipient, test engineer for Fox Factory Inc. and product development at Rock Shox Inc. He also co-founded Santa Cruz Bicycles, raced outdoor AMA MX Nationals and Supercross races in 1978-1979. In 2016 Mike founded Click Suspension Labs with the focus on low friction solution for suspension seals and fork oil additives. They now have a lubrication additive called NANO7™. They say that the oil additive improves slide friction by introducing billions of carbon coated fluorine particles to the seal compound and fork oil. The seals need a break-in period to allow the additive to absorbs into the pores of the rubber. The additive will also find its way to all the internal moving parts to further reduce slide friction. The oil additive is compatible with all motorcycle fork oils. They have logged hundreds of test hours on the Liquid A Kit™ seal system and have enjoyed winning results at Loretta Lynn’s, District 36 Hare Scrambles and many other off-road racing events. Liquid Kit™ fork seals are manufactured in a ISO Certified OEM seal factory.
Retail price per seal kit: $72.50

MXA MOTO TIP // THE CORE OF YOUR STRENGTH IS YOUR CORE
MOTO TIP: When you ride a bike, your feet are planted on the pegs and your hands grip the handlebars. When you go through a set of whoops, the muscles between your hands and feet do all the work. That is your core. The first time you ride a Supercross track with a big set of whoops it hurts to laugh the next day. If you are building big biceps to improve your riding, you are barking up the wrong tree. Focus on your core. A strong core will improve your riding.

NASCAR INSPIRED KTM 150SX 2 STROKE SHOOTOUT
After Cooper Webb got up from this crash with Chase Sexton at the Detroit Supercross, he got back on his bike and continued riding—only at an excruciatingly slow pace and with only one hand on the bars.
After the Detroit incident where Chase Sexton landed on top of Cooper Webb, a lot of people were asking why Cooper Webb was allowed to continue the race, even though he was riding around with only one hand and going around the whoops. They felt he should have been black-flagged for cutting out the whoop section, but the AMA officials did not black-flag him, when asked later about allowing Webb to continue, the AMA’s Mike Pelletier told RacerX’s Davey Coombs that there was no precedence for black-flagging a rider simply for riding slowly. Is there?
Cooper’s bike looks no worse for the wear of being landed on—except for a slightly tweaked clutch lever.
In truth, there is a rule that covers riders who are no longer at race pace, especially those just riding along the edge of the track. They can and should be black flagged by AMA officials as being a danger to themselves and to the riders going full speed around them. Here is the existing (and obviously rarely read) AMA Supercross rule Rule 4.15 l. It reads —“During a race or qualifying session, a rider must always attempt to succeed. If not, he or she shall not be allowed to continue the race or qualifying session and may be penalized by Race Direction.”
This rule should be used for riders who are no longer at minimum race pace, riders who are putting along the side of the track waiting to get even with another rider and for riders who are not jumping the doubles. And it goes without saying, it applies to riders who are riding at a slow pace with only one hand on the bars and leaving the racing surface to avoid obstacles they cannot manage.
