Creating a Rumble on the custom scene Written by Duncan Moore - [email protected] There has been an ever increasing use of large front wheels on custom Baggers over the past few years, but large diameter wheels used at the back of a bike have been a rare sighting. Uwe Sickert of MotorVisionen is changing that view with his latest build ‘Rumble’ USTOM builds based around the board track theme are a common sight at any custom show these days, so it takes something special to make an example of the genre stand out. In the case of Rumble, from MotorVisionen, at Dresden, Germany, that special something is the use of 23in wheels front and back. The build of Rumble began in early 2011 when Uwe Sickert, of Motorvisionen, won a RevTech motor as the prize in a show where he had a previous build on display. The 110ci motor was pressed into service once Uwe was asked to compete in the Biker BuildOff at the Custom Show in Bad Salzuflen the following year. With the motor as a starting point in the shop’s jig, Uwe began measuring up, and with a design finalized had a single downtube frame made for the project by Penz Performance. To accommodate the C Stainless steel was used to create the bike’s tank badges www.AMDchampionship.com A complex linkage system allows the hand shift to be situated on the right-side of the tank and still operate a regular gearbox larger wheels while retaining a short wheelbase, the frame was built without a seat post. A Suzuki GSX-R 750 was sourced to supply the USD front end. The right side lower leg was shaved and on the other leg a custom brake mount was fabricated to carry a single GSX-R radial mount, fourpiston caliper. The one-off bracket was needed to allow the caliper to work with the over-sized custom rotor, which has had the bike’s name and the shop’s website address machined into it. The wheel that carries the custom rotor is a 23 x 3.25in DNA Mammoth 52-spoke, wearing an Avon 130 60 R23 65V tire, and the same combination is The complete front end from a Suzuki GSX-R 750 was used on Rumble and combined with a 23in DNA Mammoth 52-spoke wheel used at the rear of the bike. The only difference is the use of a DNA Sprokster, which works with a GSX-R rear caliper. With a rolling chassis in place, Uwe was able to start detailing the bike, which includes some unusual details. Below the six-speed RevTech gearbox, a AMERICAN MOTORCYCLE DEALER - DECEMBER 2013 55
