Top Speed 2001 FZS600??

[darrsi]

Err a 51 plate in fast blue with micron exhaust absolutely will not ever do an indicated 142 mph...that would be madness. Equally a similar bike cannot do 130..two up

135mph, with a passenger, been there done that, and only shut off 'cos a car moved into my lane about a quarter of a mile ahead of me, but it was still going strong otherwise.


As for yer mans bike, i would say it HAS to be restricted, otherwise for this particular bike to have such a poor top speed through a fault i'd imagine it would run and sound like a biscuit tin full of nails, or if it was an air leak for instance it would be bogging down like mad.
Even when restricted though i'm sure they're meant to go faster than that, so something is certainly very wrong either way.
