2014 HUSQVARNA TC450 Dear MXA, I’m interested in buying a new Husqvarna TC450, but I don’t want to do it until I read MXA’s test. When are you going to start testing the 2014 Huskys? David Garland via motocrossactionmag.com David, you don’t have to wait any longer. Even though MXA went to Sweden for the 2014 Husky intro (turn to page 86 to see the story), you can just read MXA’s 2014 KTM 450SXF test in the October 2013 issue or on the MXA website at www.motocrossactionmag.com. The 2014 Husqvarna TC450 is basically a KTM 450SXF in white plastic.
HIGHS AND LOWS Dear MXA, I have recently purchased a 2013 KX450F. I am 53 years old, weigh 175 pounds and am a Senior Novice. What is the difference between the high- and low-speed compression? And, is the stock KX450F spring proper for my weight? Paul Weers via motocrossactionmag.com The rear shock has an outer dial for adjusting compression during high shock-shaft movements and an inner clicker for low shaft speeds. Riders assume that high-speed shock movements occur when they flat-land from a big jump. The truth is, jump faces, landings, medium-sized bumps and rollers are all low-speed shock movements. It’s the smaller stutter bumps that really get the shock moving quickly. Use the outer dial to adjust the ride height of the rear while in motion over those high- speed shock-shaft travel situations and the low-speed dial for everything else. Also, the 2013 KX450F spring is proper for a 175-pound rider.
RUINING A GOOD THING Dear MXA, I have a 2001 CR250. I am putting the engine in a 2007 frame. I want to bling it out. Who makes the largest big-bore kit? I would like to get as close to a 300cc as I can. Rusty Davenport via motocrossactionmag.com Rusty, your whole idea has some serious flaws. First, you want to take one of the better CR250 two-strokes and put in a piston so big that it will run like a John Deere tractor. Then, you are going to take that engine and put it in an aluminum frame. Far be it for us to dissuade you from your dream project, but we would recommend that you rebuild your 2001 CR250 to mint condition. Spend your bling money on a port job and a pipe and have a classic motorcycle, not a Gyro Gearloose concept bike. ; THE DOWN LOW ON A LOWDOWN Dear MXA, I’m just a Novice rider, but I wish that I could lay my bike over in the corners the way the MXA test riders do. What’s the secret? Vance Helms via motocrossactionmag.com Virtually anyone can rail a berm if they are totally committed—keep the throttle pegged through the corner, and focus your eyes at the end of the rut, not at the beginning. It is mostly about practice.
PICK ONE FROM COLUMN B Dear MXA, I have a 2011 KX450F. MXA recommends swapping the stock triple clamps for ones with less offset and adding longer aftermarket linkage, but my budget allows only one or the other. Which would have a greater effect on handling? Doug Humboldt via motocrossactionmag.com On a 2011 KX450F, the triple clamps will improve the handling more than the linkage.
DID YOU GET A DEAL ON THEM? Dear MXA, Can I use a NGK BPR6ES spark plug in my 1989 Honda CR250? Rob Hoffman via motocrossactionmag.com No. The heat range of the BPR6ES is too cold for a CR250 two-stroke. You would need an “ 8” heat range plug, like a BR8EIX, B8ES or B8EVS.
THE POOR MAN’S STEERING DAMPER Dear MXA, I race motocross in Uruguay, South America, but once a year I go to Argentina to race a beach enduro. It has long straights, and my Kawasaki feels unstable in the sand. What can I do apart from having to buy a steering stabilizer for one race? Felipe Calderone via motocrossactionmag.com The simplest and cheapest solutions are: (1) Slide your forks down into the triple clamps to slacken the head angle. ( 2) Tighten your steering head bearing to create a poor man’s steering damper. ( 3) When in doubt, lean back and gas it.
It’s all in
