A few months ago, we were introduced to Matt Harris, a motorcycle builder from Alcoa, Tennessee. His shop, 40Cal Customs builds custom motorcycles, and often uses Coker Tire products when the rubber meets the road. Leading up to SEMA 2015, Matt clued us in on a cool project that he worked out with Red Kap. The Nashville, Tennessee-based clothing company makes products that are a popular choice for automotive work uniforms, and decided to ramp up its SEMA presence at this year's show. With this increased effort, Red Kap had an awesome booth in the North Hall, and included a live motorcycle build by Matt Harris. We followed along with the progress on this Harley Davidson Shovelhead, from a bare hardtail frame and forks on Monday to a complete, running motorcycle on Friday. We love the nostalgia drag racing look, with narrow tanks, a super cool tire and wheel combination.

[products] When Matt told us he wanted a nostalgia drag racing theme with the Red Kap Rocket, we tossed around a few ideas and came up with a cool combination. Up front, Matt is using one of our Firestone 275-21 motorcycle tire, mounted to a RKB Kustom Speed front wheel, nicknamed the "Tennessee 10 Spoke", which resembles an old spindle mount American Racing wheel used on drag cars in the '60s. The gold paint is a tribute to the Dow 7 coating, which was used to protect magnesium wheels back in the day. The rear tire and wheel combination is just as interesting and cool. It starts with a Rocket Racing Strike, sized at 15x4.5 inches, mounted to an M&H Racemaster 4.5/26.0-15 racing tire. The M&H tire is actually designed for the front of a drag car, but it's a perfect fit for the rear of this race-inspired motorcycle. A little bit of custom fabrication was necessary to mount the car-style tire and wheel to the rear of the Red Kap Rocket, but it was oh-so worth the effort. Check it out.
