This “Norvin” combines a Norton Featherbed frame and Vincent Rapide V-twin, the seller reporting that this fantastic looking combination was first registered in England nearly 60 years ago. The ad doesn’t touch on running condition, but condition is reminiscent of a well-cared for, possibly largely original bike, and though now Stateside, sale includes what look like original number plates. Find it here on eBay in Saint Louis, Missouri with no reserve beyond an unmet $50k starting bid.
Reads much of the brief ad: “Offered for your consideration is an excellent original example of one of the first hybrid custom motorcycles. The name Norvin comes from the combination of Norton Featherbed frame and Vincent V-twin. This particular machine was first registered in the UK in 1958. The bike still retains its number plates and last registration, and is remarkable in that unlike most other builds ,the wideline Featherbed frame was modified so as to not have to resort to cutting off the transmission of the Vincent crankcases. A wonderful example of an original performance cafe racer.”
Vincent motors are always spectacular looking things, and this 998cc unit was originally fitted to a Rapide. Factory rated at 45 HP, the seller doesn’t touch on running condition, but everything looks in order here. Vincents were expensive, high-quality, and powerful machines, and in combo with the then state-of-the-art frame, should make for a great riding bike.
$50k+ is steep, but as far as original cafe builds go, they don’t come much more desirable than this.
