Yamaha RZ 250 RR YPVS Specs - RZ250RR Specification
Since Yamaha RZ250R was Launched, RZ250RR was added in February 1984 as a variation model of RZ 250 R to compete against rival racer replicas that appear one after another.
The big difference in appearance is not a bikini cowl like the RZ 250 R, but a racey image cowl like the commercial racer TZ250 that covers the side of the engine. This cowl is the same as the upper cowl for the RZV500. In addition, a full cowl and single seat can be selected as an option, and the lacy could be emphasized.
The improved point extends not only to styling but also to the engine, which is the key to its potential. By adopting a carburetor with a forced opening and closing power jet and a cylinder that has been re-examined the port shape.
the maximum output has been increased to 45 PS, the same as rivals, at the limit of the self-regulation upper limit at that time. The muffler has also been changed to a separate silencer type design with a more chamber-like image.
The front brake caliper has been changed from the one-push type to the opposed piston type for the suspension, improving braking power and control ability. Also, since the meter and cowl are changed from the Yamaha RZ 250 R handle mount to the frame mount, the lightness around the front is greatly improved.
In addition, tachometer change from mechanical type to electric type, change of winker shape, separate handle with a more racer-like image mounted on the top bridge is also available from this model. In addition, there were limited 2000 YSP models that were sold only at the YSP shop, with coloring that does not exist in normal color variations and full cowl and single seats as standard equipment.
Unlike the RZ250R, which was sold for a long time until 1992, the RZ250RR ended its role with the debut of the full-scale racer replica TZR250 in 1986 and disappeared quietly.
