That's a screenshot of a trail I recorded on my bike, recorded using everytrail app on my galaxy note, this is the GPS readout, not my clocks.

102 mph, not down a big hill as you can see. Doubt all you like, I have no reason to lie
Thanks
Rob

It doesn't seem too unreasonable to hit 102mph 'real' speed to me.

Though, looking at your graph, we see that's the only bit you even got over 90mph, which would make me question if it was a 'blip'.

What I've taken issue with is that it accelerates 'well' in the 90s - I've ridden bikes with similar and a bit more power and none would I describe such.

With the right aerodynamics triumph got a 650cc twin making around 65hp to 214mph in 1956.

[Cheerfulgrin]

Let's just say it was a very twisty airstrip and I wasn't trying to go fast most of the time which is why it doesn't peak very high most of the time.
I will try and find a straighter airstrip in future and post results along with a weather report, but I doubt posting that would make any difference.

By pulling well to about 100 I meant I don't need a hill, wind, or anything else and it doesn't creep to 100 it goes upto it at a decent rate.

I haven't ridden anything faster, so maybe that claim maybe unjustified in others eyes, it's my opinion at the end of the day.

FFS - it's my own opinion, not yours or anyone elses, what words I choose are up to me.
I think I've proven the 87mph top speed to be wrong so it's all about my definition of pulling well now!

Whatever!

It's a sensation - I've sorted the worst of reception issues by bending the clips back.

If you really want to convince me - two way run at somewhere with proper timing equipment.

If you'd provided GPS data that didn't have only one spike where you went over 87mph, I'd have been more convinced.
Ironic - as I wasn't even claiming it was untrue. 102mph on a GPS occasionally doesn't seem that unlikely for the right conditions on a faired bike making a smidge under 30hp.

For proof we need a video of you riding it at 102mph for 3 mins.....backwards,dressed as Jimmy Saville while singing a Robbie Williams song (any will do, they are all equally shite)

I won't be providing evidence even though the last suggestion is very tempting, instead I shall continue to ride my bike how I want to and anytime I go over 87mph I will have a very Smug Grin on my face, safe in the knowledge that I have the fastest hyo 250 in the world as it can't go faster than that and defo not uphill into the wind

See if you can get a test ride on a ZX6R and rev it to the redline in 2nd at full throttle, take spare underware


I do think that given a very long run at it the GT250 can crack the ton, a mates kwaka 250 did it regularly (following her my speedo would be north of the ton, hers read higher then mine) but as for accelerating well, you need to try a proper bike, problem is that once you've had that acceleration you either shit yourself and avoid it by entering the chaps and tassels world of cruisers, or you want more and more

I believe most 600s will do 60 in about 3 or 4 seconds, so that's twice as fast as mine, but, my 125 did 60 in about 3 minutes and the fastest car I have driven did 60 in 8 seconds, so my little bike feels pretty quick to me.

I'm looking forward to experiencing bigger bikes in future but can't see the point of something that'll do 170 tbh, most of the roads round me are too rough or bendy to go 70!

The Kawasaki Ninja 250 with a claimed 32bhp or 25.8bhp r/w according to the road test I read in a Spanish magazine on Holiday, would do about 102 true mph. Speedo reading over 110mph at that speed however.

I'm sure if got some road test data for the GT250R somewhere, but id expect that it would struggle to top a true 95mph in controlled test conditions. 95mph for a 4stroke 250cc bike with under 33bhp is still reasonable though, and only the fastest 125cc 2 stroke's would be able to convincingly top 100mph, and most of the Japanese sports 125's would be in the mid 90's mph as well.

I'd be happy with the performance level of the GT250R for what it is. You could look at the rare 250cc 4cyl sportsbike's and think they are massively better, but them are so focused and all the pulling power is at well over 12000rpm, so the effort needed to get a true 115 ish mph, over a 250cc twin, is in my opinion not really worth it, for an everyday bike.

On your graphs, the gradient of the speed flattens out anytime it is over 75mph.

Also, the point of 100mph, coincides to a dip in the elevation also.

As for collecting accurate data, then that peak will be neglected as an anomaly due to it's singularity, a graph showing a sustained speed, or multiple peaks would be better evidence, additionally, the GPS Co-ordinates at which that speed was reached would be beneficial to proving your point also.

Those are all fair points, but it wasn't a speed test, I offered a review of the bike from an owners point of view, then felt I had to provide evidence the bike could do 100.
I rarely go over 80ish, but that's not cos of the bike, more to do with me being a novice.
Whenever I have wanted to do 100 (indicated) it hasn't been such a struggle, that's all I was trying to illustrate.

All this fuss about the top speed is irrelevant, what I was trying to get across is that it's been a decent bike for me as restricted licence holder and I would recommend one to anyone on the 33bhp licence.

Good bike for a 33bhp license nothing more. To be fair to you, you never said it was anymore than that. Ample top speed aswell.
