The YAS1 was imported into the UK from late 1968 with only minor changes until its demise in 1971. It was very high tech for the 60s. The top speed was claimed to be 80mph.
The bike was bought on a well known auction site as a basketcase in February 2005 and due to the difficulties of finding replacement parts it has taken the owner Malcolm two years to restore. After a dummy rebuild it was found that lots of parts were not correct for the bike or severely corroded which made the restoration a challenge. The bike was finished and MoT’d on August 11, 2007 and has kept its original registration number.
Malcolm has tried to retain most of its original equipment that was correct for the bike although as can be seen it has either been re-plated, re-chromed, re-painted or refurbished.
Hardest parts to source were silencers, which still needed repairing, and mudguards. Again, they weren’t perfect, but were a basis to create something usable. The originals had corroded beyond repair. The only non-standard part on the bike is electronic ignition made by Newtronics.
