YAMAHA RAZZ (SH50)

yamaharazz
First introduced in 1987, the SH50 Razz is a nice little scoot that was released to replace the Salient / Riva 50 (CA50). In Canada this scooter was called simply the Razz but in the USA Yamaha chose to include it in their Riva family so they dubbed it the Riva Razz.

The Razz was Yamaha’s entry level 50cc scooter for the period (with the Jog being the higher end 50cc). The Razz lacked a continuously variable transmission (CVT) and instead got just a single speed transmission. As a result, modifying a Razz to go faster is hard because you need to do something about the gearing. In its stock form, the Razz tops out around 30-35mph. Yamaha also sold a moped legal version (SH50M) of the Razz that was limited to about 25mph. The Razz also got just a left side mirror. A right side mirror was available for an extra charge.

Besides the single speed transmission, The Razz is pretty normal fare. It’s got the typically modern Japanese scooter look with a sufficiently peppy air cooled, 2-stroke 50cc engine, automatic oil injection, electric start and auto choke. The Razz was also the lightest scooter available after ‘87, weighing just 115 lbs dry. In 1987 Honda’s Spree (94lbs) held the title but it was dropped after that year. The Razz’s lightweight contributes to it’s great milage which Yamaha claims is 100mpg. Realistically, you’ll probably get about 80mpg with this scooter.

The Razz shared some parts with its Jog family member. The mirrors and entire front headlight/blinker array appears to be the same and so does the rear taillight and blinkers. If you are looking for parts for your Razz you might want to check (on the microfiche at BikeBandit.com) t

o see if the Jog parts are the same. One downside to the Razz is that storage seems to be non-existant.

The SH50 enjoyed a surprisingly long run from 1988 to 2001. That’s even more impressive when you consider that it was sold alongside other popular Yamaha scoots like the Zuma / BW’s and the Jog.

Yamaha sold a few accessories for the Razz, specifically a windscreen, rear case and rear basket. You can view those here.
