A bit of Origami to start the year off!
Ultra-Realistic Paper Crafts: YA-1
To commemorate 20 years of Yamaha Paper Crafts, we have recreated Yamaha Motor's first motorcycle, the 1955 YA-1, as an Ultra-Realistic Paper Craft. this is a free download.

Looks like just a 'D1' BSA 'Bantam'! And wasn't Kawasaki's 650cc effort based on a BSA 'A10'? The story goes that they bought one, stripped it down, made improvements where appropriate and then into production. Production was helped by modern machine tools unlike for BSA.
Scant regard for intellectual property is not a recent phenomonen.
Please take care and stay upright.

PS - We pinched the 'Bantam' design from DKW at the end of the War.
