Compared to some of the shit people rode back then, like my mates CJ250, it would have been a revelation.
To be honest I doubt my RD250E was much faster flat out
The Z was pretty quick but as mentioned, the engine grenaded within 20k.
The CB350S that was also in the family soon after got to around 90k before it became 'beyond economic repair'. The engine still revolved (slowly) but the fork chrome had worn so thin new seals did nothing, the brakes were worn out and the tank was mostly araldite filling the rust holes.
