1970 Yamaha CS3C - May 2019 Window Bike
May's window bike belongs to Holly a rider we met through racing with the VRRA and seeing her and her partner's beautiful collection of Yamaha's at Motosocial's in Toronto. We were happy to pluck one of her rare Yamaha's to place in our window for the month of May.
A few words from Holly on the CS3C:
The bike you have is a 1970 CS3c Yamaha. It's a 200cc two-stroke twin that was produced for two years between the 180cc CS2 and upgraded 200cc CS5. These models all preceded the Yamaha RD series which took the two-stroke world by storm starting in 1973. The CS3 machine was way ahead of its time as the 70s began and these 'little' bikes could hold their own on the streets and in the dirt.
The CS3 came in two basic models and three colours. The street version CS3 and CS3b with low pipes came in brigade blue and metallic purple, while the rarer street scrambler, the CS3c, was always candy green.
As per Yamaha's forward-thinking ingenuity, the CS3 (along with other models of the late 60s) included an oil injection system which put the 'norm' of two-stroke engine seizure firmly in the past. Nearly unheard of for bikes of the time – especially two-strokes – the electric start was a selling feature and the twin-leading front brake gave the bike the quick stop to match the zip and acceleration of its crisp little engine. With 22bhp at 7500rpm it was a great bang for its buck at the time. There were just over 5000 CS3c models made. Very few exist today in their original form. Many of the CS3 models were turned into small displacement race bikes, which we still see on the VRRA and ARHMA circuits today.
This particular bike was originally purchased and registered in New Jersey. Brought up to Canada about 20 years ago, it is ridden and enjoyed as an unrestored survivor. It is part of a collection of eight vintage Yamahas that myself and my partner, Dean, have picked up over the years. In the 60s and 70s my grandparents had a Yamaha sales and service shop in Brantford, and with a hefty stash of NOS parts still available to me, it kind of makes sense to keep a few old Yamahas on hand.
