You'd be surprised how wrong the speedos are... The other day we tested my mates one.
His speedo was saying 85mph... gps was saying 65 haha

Re: the world quickest standard sj
my record top speed running my old 970cc with 31" tyres (actually measured just over 30") was 74mph on the gps, it was on a bloody long, flat, straight bit of road

Same for me, long flat straight A-road.
My speedo's pretty accurate. 32-ish is 30 according to the laser speed signs, so I figure if you double (and a bit) the speed then you double the inaccuracy. 75's probably about 70, which is what Suzuki said the top speed was.

There's three ways of doing things:
The right way,
The wrong way
And my way, which is like the wrong way but faster.

Think my extra 4mph would be from the larger tyres.Edweird wrote:Same for me, long flat straight A-road.

Re: the world quickest standard sj
The fastest I've ever got mine to was a speedo reading of 62 with the GPS reading 75.
That was down the steepest straight road in Norfolk.

Re: the world quickest standard sj
It's all about the bigger tyres... going from 195x80 to 235x85 has boosted my cruising speed from 60 to 70 
Edit: Bigger engine helps as well

Re: the world quickest standard sj
when mine was still standard I got 89 down a big hill.
since having the 31s its never gone over 65 on the speedo but I guess it must be more than that on GPS. When its back on the road with the 1.6 lump I will try it on GPS
