Suzuki GS550 Tracker by Mark Alderfer

Suzuki GS550 Custom Tracker

Today, we’re excited to bring you “The Blue Bike,” a 1980 Suzuki GS550L tracker build by Mark Alderfer of Pottstown, PA. This bike screams class, and the lines and detail immediately leapt out at us. What’s more, the GS550 makes a fairly uncommon base for a build.

Suzuki first introduced the bike in 1977 as a new member of the GS family, the company’s first line of four-strokes. The bike came with an air-cooled, 549 cc four cylinder engine that made 49 horsepower. It weighed about 430 pounds, and remained in production until 1985. The GS550L was a US-styled version first introduced in 1979. Basically, it had more of a cruiser look.


GS550 Custom:  In the Builder’s Words

I built the bike as a cheap project to keep me busy over the winter a few years back. The only thing left of the original bike is the frame. The tank is from a gt380, the forks and motor are gs550E, wheels are gs1000, rear shocks are from Ebay, and I made the seat and tail section. I also made a completely new wiring harness for the bike. My friend Neil helped me paint the tins and Paul Leech did the striping. The bike is a blast to ride and I’m really happy with how it turned out.
