Triumph Thruxton Street Tracker by Britalmoto

Robe Crafts Tracker: Triumph Thruxton Street Tracker

We have a very special build today:  The “Robe Tracker” by Ivo Tschumi of Britalmoto, based in Siglistorf, Switzerland.  The base bike is a 2004 Triumph Thruxton.  The Thruxton, as you may know, is based on the Bonneville, but with an array of cafe-inspired modifications:  clip-ons, rear sets, seat cowl, reverse cones, etc.

Ivo set out to design and build this bike for himself, a Thruxton street tracker that performs as well as it looks.  What an incredible job he’s done, and under a tight deadline while recovering from an ugly high-side at the track!

Thruxton Tracker

This tracker build simply blew us away the first time we saw it, and we love a build that “goes” as well as it “shows.”  As Ivo says…

“The Robe Tracker is under 180kg now (with empty tank/ the original weight of a Thruxton is between 220/230kg) and with the 78rwhp it rides like a BMX…so much fun!”

We will let the man of the hour tell us about the bike himself.

Robe Crafts Tracker:  In the Builder’s Words

Triumph Thruxton Street Tracker

First of all, I built this bike for myself, because it’s still a lot of fun for me to create the design for a bike…and after all the customer bikes, I felt that I wanted to realise my own ideas again.

Otherwise Mario Burkhardt and his crew invited me to Show “Art and Wheels” in Basel, Switzerland, which opened the doors first time this spring at May 16th 2015.

Several top customizers were there from Switzerland (Danny/HardNine Choppers, Coni/CCCP, etc) and other countries (Yaniv Evans/Powerplant Motorcycles, etc), as well as other big names from the custom scene like Shige from Mooneyes…just to tell you  some of them.  So it was a big honour for me, as a “little/unfamous” customizer to be part of this show!

So then…I was on time to finish the bike for the show…but six weeks before May 16th, I had a highsider at the racetrack. First, I thought that it was not so bad, only some bruises and i can go back to work some days later.  But two days after the crash I went to the hospital because my shoulder was still hurting badly.  I came out in a wheelchair, my feet in a gypsum, a cracked bone at my leg and a bruised hip and shoulder.

For 1.5 weeks I stayed at home…but I still want to finished the bike…I really want to be part of the show.  So I dragged myself to the workshop and started working again–welding, milling, and all the other works with the gypsum and the sticks.  That wasn’t as easy as I thought…and I only had 4.5 weeks!

Then almost one week before the show, my painter dropped me like a hot potato…and i just thought:  Fuck…all that stress for nothing.

Luckily, I found another guy who finished my paint job really quickly. I also want to thank my ex-girlfriend Johanna.  She did the stripings and letterings in the last three days. I also used this show to promote my new label Robe/Crafts which concentrates to kit out bikes and maybe later the rider also.

The tank and seat i modeled and designed with clay. A good friend, Chris Maertl, built the tank in alloy for me. He’s done a lot of work for me in the past. The negative for the seat I did by myself…a other company did the positive because there was not enough time anymore.

Also the handles I did conventionally at my workshop from alloy 7075. Another good friend did the CNC machining to fit the gas cables.

Other parts like the front mask, holders, fork covers, complete footrests, chain wheels, cover plates, number plate/turn light holders are done by myself.

All these parts from the Robe Tracker and older parts I designed for customer bikes as well, you can buy in my onlineshop soon.

The Robe Tracker is for sale now…please contact me at [email protected]!

Big Thanks Goes out to…
