I went to Antwerp yesterday and met a Dutch guy (also called Rob) who has been building this bike for 4 years, whilst riding it, when it's not in bits for remodelling.
It started life as an ST4 rolling chassis with a 900SSie motor and of course, a Monster tank.
Vintage tacho and 916 bars,
he has a tiny Sigma bicycle speedo which unclips when not in use.
The tank is done with gold leaf under six coats of laquer.
Now that's what you call a tail-chop!
Sport Classic front guard and BMW R75 headlight.
Seat came from a BMW R50, adapted and recovered by Rob.
2 weeks ago, it was in bits having the frame painted.
It's a work in progress, next to go on are stainless clip-ons, fashioned in keeping with the '20s-'30s styling.
Nice work Rob! Ride safe and see you around.
