BMW R100 "Flying Spark"

Our latest custom bike

This conversion is based on a BMW R100 RT from 1981 – completely rebuilt, 100% restored and a real eye-catcher. The 100% road-approved motorcycle in Switzerland convinces with its very special paintwork, a new exhaust system and many small details that make the heart of every lover beat faster.

Harley-Davidson "Dirty Bob"

Dirty – Rusty – only the best

An American legend: The Harley-Davidson Softail FXBBS built in 2021 has been converted into a high-end bobber. Only the best – no matter where the eye goes.
From the very first second, the motorcycle conjures up a laugh on the lips of every Harley lover and all other motorcycle fans: The exhaust system from Dr. Jekill & Mr Hyde makes the engine from Milwaukee sit up and take notice – the wider rear wheel rim and the 21″ rim at the front of TTS Motorcycles gives the Street Bob a juicy waist.

Harley-Davidson "Forty Eight"

Brachial – Black is beautiful – Exclusive

The American motorcycles from Harley-Davidson are coveted and have the largest fan community in the whole world – and rightly so.
Our latest conversion is based on an XL1200X built in 2015. The Sportster is one of the best-selling Harleys worldwide. We deliberately opted for a cozy city bobber.
The flap exhaust system from Dr. Jekill & Mr. Hyde has a brute sound – thanks to Euro 3! The on-frame seat forges itself perfectly into the tank line and gives the motorcycle a cheeky look. The gangster handlebar is not only comfortable, but also looks unmistakably good.
