yamaha Beluga 150x216 YAMAHA RIVA 80 BELUGA (CV80)The Yamaha CV80 is an 80cc two-stroke motorbike that has been created from 1981 to 1987 and also was sold around the globe.

Efficiency:
For the first handful of years, the CV80 was particularly slow for an 80cc, slower than even a modern 50cc four-stroke. It’s rivals (i.e. Honda NH80 and also Vespa P80X) produced substantially additional power. Early CV80s

(pre 85) best out at an okay thirty six miles per hour nevertheless it take forever to get there. I when rode on my stock 83 CV80 alongside my brother who was on his Honda Aero 80 in addition to a voyager. İn spite of getting 2 bodies on the Aero 80, they were nonetheless blowing by me up hills and off the line. It was humbling just how much slower the CV80 was. The main factors for the CV80′s anemic overall performance are the restricted exhaust program, tiny carburetor and also tall gearing that did not let this motor rev. It appears that Yamaha went overboard once they attempted to make this moped docile and friendly.

Part way as a result of the CV80′s design life, it appears Yamaha recognized they’d extremely restricted this motorbike, so they made a number of updates that considerably enhanced the overall performance. Yamaha changed the thirteen millimeters carb to a sixteen millimeters carb, changed the exhaust using sort of an expansion chambered design and they introduced a new cylinder, head, variator, reed cage and also intake manifold (and more). These updates were implemented at distinct occasions in various nations. Europeans seem to have gotten these changes for the 1983 model year, though USA consumers did not get them till the ’85 design year. In Canada, it seems that Yamaha implemented these modifications gradually more than a handful of years (’84-’85).

The overall performance distinction between early and late editions of the CV80 is very dramatic. The early product CV80 is rated at 4.7hp, whereas the revised model generates 6.9hp. Accordingly, the late product CV80 has considerably superior acceleration and tops out around 75km/hr as opposed to 60km/hr. A European magazine compared these models and recorded 0-60km/hr times of 15.8 seconds (early version) compared to 10.5 seconds for the revised type. I advise anybody whos in the market for a CV80 to hold out for 1 of the enhanced designs from the later years. These later CV80s also have a side stand that is a good touch. The side stand is just not effortlessly retrofitable for the reason that it needs a mount welded towards the frame.

Electrical Method:
The electrical method is an additional weak point of the CV80. The electrical method is rated at a mere forty eight watts of six volt energy at maximum output (which occurs at the redline). İf you take into consideration that the front lights is twenty five watts, the dash lighting is fifteen watts as well as the taillight is 5 watts, that indicates you are applying up forty five watts only driving along. So in case you apply the brakes (twenty five watts), use the horn or flick on the blinkers (seventeen watts x two), your demand is dramatically exceeding the obtainable provide. The result is borderline unsafe. If you are driving a curvy street at night and you hit the brakes for a corner, the headlight dims so drastically that you are left virtually in the dark. Even worse is slowing down for a turn exactly where you apply the brakes and flick the blinkers on. Its fairly ugly. A further trouble is the fact that the electric start out just about never functions mainly because the electrical program are starter motor are each so weak. Even with a brand latest battery you will merely have the ability to use the electric start when the scooter is warmed up.
