1972 Yamaha R5C (R5)

Photo of a 1972 Yamaha R5C (R5)

No longer owned


Bought locally via eBay, from a gentleman who had accepted it as trade for contracting work, rode it a few times and stored it for 25 years in his garage. After only a little work on the carbs and a good cleaning she fired right up.

I've replaced only the stock bars with clubmans and new grips, taking off the sissybar that was fitted, replacing the front tire, and most recently installing vintage rear-sets and a NOS right-hand mirror. The original intent was to strip this bike down to it's bare essentials and make a cafe racer out of it... however, the bike was in such good condition, and R5s are not all that common (unlike the later RDs) that instead I've kept everything relatively stock with only a few vintage racy bits thrown in.

This thing is suprisingly fast for its size and age, lifting the front wheel in the first two gears and keeping up with bikes twice it's size. It's also extremely flickable and great fun around the city. It was the direct descendant of the Yamaha factory TR production racers. Dirty, loud, crazy quick and relatively affordable when new (and more so now!), it was, and still is, a giant-killer.
