2015 Street 750 Gets Streamlined at Number 8 Wire Motorcycles

Seeing the light

For as many people that are fans of the Street 750, there are also naysayers and detractors of the bike. One of those people that didn't care too much for the Street was actually the owner of this bike. When Colin Cornberg of Number 8 initially suggested that the bike serves as the basis for the build the customer was a bit skeptical. However, after hearing Colin's spiel on why and seeing sketches of the end product he came onboard.

Trust in your builder

"He initially wanted a CB750 or similar. But I worked on those bikes for years in my former service garage in Missoula, so I talked him into something with a little more reliability and performance." The Street was the perfect foundation for the two major themes of the build: throughly rideable and a touch of cafe racer. With that being said, the 2015 Street 750 was to receive some performance mods along with new bodywork.

It's a learning process

“I made two-and-a half-gas tanks before getting it right,” he says. “The learning throughout that process was invaluable—the biggest challenge was retaining the monstrous stock fuel pump.” Colin utilized aluminum and worked with hammers, dollies, a shrinker stretcher, and an English wheel to get the Street's new look to come together. The entire subframe got cut off and then a new one was constructed using a TIG welder on a manual tubing bender and a tubing notcher.

It's so stable

“To get the rear shock nice and tight in the rear end—and still have a bike that handled well—I needed a linkage to get an acceptable shock leverage ratio. I decided on the relatively common linkage from a Ducati 1098 and set to work designing the suspension based on that, and the visual lines I wanted to achieve with the subframe.”

Go to match the show

To squeeze a little more power out of the motor, a two into two TIG-welded stainless steel exhaust system was fabricated by Colin with a pair of Cone Engineering mufflers on the ends. Then a Vance & Hines high flow air filter with custom cover and a Fuelpack ECU was installed. “The bike sounds great, runs great and absolutely rips,” he says.

Unique but approachable

“Part of the idea was also to have a finished product that was incredibly custom, but still serviceable by an H-D dealership mechanic. I managed to retain almost all of the stock wiring harness, all the stock relays, fuel pump, and even the horn!” To read about everything that went into the bike and see more pictures, just click here.
