Just why is the 1985 F1 the best of the RD/RZ YPVS range?
Whilst any RD/RZ is good it’s even better if you can get the exact model to rebuild that you really like and in that respect I was very lucky that the bike that was for sale for the right price when I was looking for an RZ project was also the exact version that I coveted.
So what is it about the ’85 that I love? Well of course we can start with the usual thing, nostalgia..

Anyway, my own history with that bike is just part of the story.. For me, there is just ‘more styling’ in this model than the later bikes which I find are somewhat ‘square shaped’ and dare I say it, a bit 'slabby'. Well, that was the look of the late 80s and early 90s of course, I guess it’s just not my thing..
The ’85 model has a blend of the old and the new from the RZ styling catalogue. What this model does is take many elements of the earlier ’83/’84 YPVS models and blends them with a full fairing that is attached to the frame (and not the bars) which was becoming standard on the racy bikes of the modern age.
If we are honest, it does now seem that Yamaha did a quick re-style job on the ’84 to modernise it for the ’85 model year, and in retrospect it shows, and very quickly (for the next model year) Yamaha restyled the rest of the bike including the fuel tank, side panels and rear end, plus adding a bunch of other changes to the bike in the hope of keeping it current in the fast moving two stroke marketplace, on a bike that was already seeing a noticeable drop off in sales year on year form when it was launched, competition from the other players was hotting up and Yamaha were suffering. Looking back today at the ’85, it’s almost like the brief was to do the ’86 restyle but the team ran out of time or budget to get it into production quick enough for close off for the 1985 model year range, and hence the front end and swingarm got done but the rest of the bodywork was left as the previous year models.

The Yamaha RZ 250 was a Liquid Cooled, Two Stroke, Parallel Twin Cylinder Sport Bike motorcycle produced by Yamaha in 1980. Claimed horsepower was 35.0 HP (26.1 KW) @ 8000 RPM.
This was a supersport model developed with the TZ250 as its base. It immediately created a big sensation after its stunning debut at the 1979 Tokyo Motor Show. Its liquid-cooled 2-stroke, 2-cylinder engine pumped out high power equivalent to 140 hp per liter of displacement. This was mounted on a double cradle frame with a Monocross suspension and other features like lightweight cast wheels to produce unprecedented running performance. Even today it remains a legendary model with a devoted following.
