Honest feedback from our customers.
Excellent Consulting

I converted a BMW K100 myself and let you guide me through the conversion. Your advice was great, thank you very much!

Hans Niederhauser

Excellent quality

The parts are a bit more expensive than in the European comparison - but there is Swiss Quality behind them and you can tell. The quality is impeccable!

Reto Wyss

Free help

I converted my BMW R80 into a bobber and bought the DTC report from Black Diamond. Mike is very courteous and sometimes helps out in the evening when no shop is open. 100% recommendation!

BDM Shorty exhaust system

People's looks are really priceless when I tell them the sports air filters are legal and registered. Thank you guys! The exhaust system sounds really great. I can 100% recommend it!
