Avenue-Authorized Filth Tracker from Classic Sykles…
Austrian-born engineer, Grand Prix motocross racer, and ISDT gold medalist Horst Leitner based ATK in 1985 after relocating to the USA. The title derived from Leitner’s patented “A-Trak” — a tool designed to cut back chain torque. ATK machines shortly grew to become common winners within the 4-Stroke Nationals, and by the 90s, ATK was one of many largest off-road motorbike producers in North America, working out of their headquarters in Utah.
Within the mid Nineties, the ATK 605 appeared, which was mainly an ATK “Cross Nation” filth bike with lights. On the time, no different dual-sport machine was this aggressively dirt-oriented. Cycle World in contrast the massive ATK to their “Greatest Twin Sport Motorbike,” the Honda XR650L:
“The ATK 605 makes the Honda really feel like a streetbike. If the XR-L is a 75/25 dirt-to-street combine, the ATK is biased 95/5.” –Cycle World
The ATK weighed 30 kilos lower than the Honda with a full 4.3-gallon tank of gasoline, and the 598cc single-cylinder Rotax was one of the vital confirmed engines within the two-wheeled world.
The WP forks had been the identical high-spec items that got here on KTM fashions of the time, that includes a big diploma of adjustability, and the seat top of 38+ inches solely confirmed the 605’s single-minded focus. The ATK didn’t actually have a speedometer, ignition key, or fork lock.
“Should you’re after a dual-purpose machine that strictly adheres to the dirtbike-with-lights dictum, then the ATK 605 is about dead-nuts good. This bike may be raced competitively in off-road races; it should do a great job of carving up twisty pavement via a canyon; and it’ll take you to the comer retailer for a quart of milk-if you carry a lock and chain.” –Cycle World
Enter our buddy Pete Sykes of Classic Sykles, who raced flat monitor in Pennsylvania’s District 6 again within the Seventies. A tragic accident took him away from the game for a few years, however he discovered his method again to 2 wheels in earnest, constructing bikes and customized aluminum components as a aspect enterprise.
“Once I retire from my day job I hope to create bikes and aluminum seat pans, fenders, and gasoline tanks. I’m blessed!”
Three years in the past, we featured Pete’s Kawasaki Zephyr 550 avenue tracker — aka “Drawback Youngster.” Now he’s again with with the 1999 ATK 605 you see right here.
“The bike was given to me by an excellent buyer and buddy who gave me free rein to make it right into a one-of-a-kind tracker.”
The gasoline tank is a one-off unit constructed out of aluminum to suit the slanted spine of the body. The race-inspired look of the light-weight tank then unfold to the remainder of the construct.
Pete fabbed up the entrance quantity plate with MX Numbers graphics, micro LED alerts, and a small however highly effective Baja Designs headlight for the look of a street-legal DTX bike — a motocross bike transformed for flat monitor racing with lowered suspension and 19-inch wheels.
“Throw your leg over this ATK605 and prepare to carry on tight. This bike can compete at your native flat monitor race or you possibly can run it as a bar hopper on Saturday evening.” -Pete
An Öhlins rear shock helps get the torque of the massive single-cylinder Rotax to the bottom, whereas Shinko flat monitor tires present grip on each filth and tarmac. Pete modified the subframe to suit the tail part and quantity boards (courtesy of New Zealand’s C•Racer), and the bike received a full rewire. Brembo brakes haul the bike down from velocity, and the engine received a full service, too.
We love the track-focused course of this ATK avenue tracker, and it’s good to see such an unusual donor, too. Even higher is Pete’s angle concerning the course of — the most effective mindsets within the enterprise:
“General the bike turned out to be a creation of my creativeness which ran just a little wild. I’m very grateful for the chance to construct bikes and don’t take it as a right. Each problem that comes my method is a blessing although typically they’re very arduous, however the pleasure you get in the long run result’s properly value it.”
Under, we speak to Pete for extra particulars on this ATK avenue tracker he calls the “Canyon Runner.”

The bike was given to me by an excellent buyer and buddy who gave me free rein to make it right into a one-of-a-kind tracker.

As soon as I had the tank achieved I ordered a fantastic seat and aspect quantity plates from C•Racer in New Zealand. I then constructed a rear seat mount that I welded to the inventory subframe.
This modified subframe allowed me to mount the seat, taillight, and aspect plates.
I fabricated the entrance quantity plate and used vinyl graphics for the numbers from MX Numbers out of Idaho. I additionally mounted small LED flip alerts to the entrance quantity plate.
The wiring was in very unhealthy form, so I dove in and stuck all the issues, which ended up being nearly an entire new wiring harness. I soldered all of the connections collectively; this allowed the bike to prowl the streets legally.
