i have a Speed Triple 1050 (2005) and it will not go any faster than 130mph. The only mod is it has an under seat Trident Wolf twin exhausts. There are no other noticeable performance issues, it rides and accelerates beautifully but just wont go above 130. I have been told this bike should get up to around 145mph. Has anyone else had similar issue and if so, what was the problem? Bike only has 9,500 miles on it.

Thanks, Steve

How are you positioned on the bike at higher speeds, my hornet wont want to go above 125mph if i keep a normal position and have to kiss the clocks to get the top speed.

Are you trying to do it by staying in top gear and rolling on?

As a general rule (I've never ridden a speed triple mind) redline it in all gears on the way up for a top speed run.

You may well find it goes quicker in 5th than 6th. On my VFR, 6th just gives it that last, slowly creeping 5mph with your head down, elbows tucked and shoulders arched.

On my VTEC, I suspect it's a bit faster at the top end in 5th than 6th, but I didn't get a long enough stretch on the autobahn to really test it beyond 144mph GPS (~155 on the clocks).

That was with an enormous top-box too (Givi Maxia E55).

i was literally kissing the clocks, tucked in as tight as a gnats chuff. i did however have a soft tail-bag setup on the back that could have acted as a sail and would have held me back. I was also wearing gore tex which was flapping around all over the place.. again this could have acted as an air brake. however, i must say i probably didnt redline it through the gears.. i will give it a go on my way home and report back Wink

Different animal but my street triple pulls to the redline in 6th and indicated 150mph, true speed is only a shade over 131 mind.

With the speed, I'd expect to be in 5th until the redline, as above, likely it will pull far better in that gear.

On my private airstrip ofc Rolling Eyes

I second the unflappy advice. I had a lot less drag when i tightened the arms n chest on my textile jacket. Not looking forward to going back to wearing it after a summer of leather!

I got 145 (indicated) out of my VFR750 2-up. It was still pulling a little when I lost concentration due to there being a police bike doing the same thing as I was but in the opposite direction.

The visual effect of the closing speed on a single carriageway was rather impressive.

I am genuinely suprised to hear how low the top speeds are on some of the bikes mentioned in this thread given their engine capacity and power output.

Bullshit.

This, extensively tested 2 600's and a 650 model (all N's), indicated 130 but more than likely 120-5 mph.

I think a 100hp bike like the Hornet ought to be good for 150mph if it was geared for it, but maybe it isn't? Naked aerodynamics won't help though.

I think 6th on the VTEC is for cruising at 100mph before the VTEC kicks in, for marginally more efficient long distance riding.

The 144 I got out of mine is from the GPS's top speed statistic. That was with a waterproof suit worn on top of leathers, but it wasn't flapping a huge amount behind the fairing. Main thing I felt was the helmet pressed against my nose, as I peeped over the screen. Remarkably stable bike at speed though.

FYI I don't think it was 130MPH, however the clocks indicated that.

i dont intend to go over 130 mph too often i just want to know if its something i should consult the Triumph dealer about. My Speed Triple pulls like a train and and beats most bikes off the mark up to 100mph, but just flat lines at 130mph whereas it should be touching 150mph. it felt like it was going quicker but clocks stayed put at 130mph.. i had it tested and its producing 129bhp so really should be hitting a higher top end.

someone suggested i should redline it in 4th and 5th before getting to 6th gear.. as this can impact top end. sounds feasible. thanks for the responses guys.. and be safe.

Download a GPS app for your phone, and get an accurate measurement of the top speed. This will be better basis for judgement than a semi-random number indicated by the clocks

What revs is it doing at 130, is it near the redline? If so someone may have lowered the gearing for more acceleration ( assuming you bought it 2nd hand and you haven't changed it ). If it isn't anywhere near the red line then maybe the engine map is out for the pipes and it needs setting up.
Of course you could just be a fat wide git Laughing

The speed four was the same with "100 oss" at the engine, you had to really tuck in tight to nudge it past 130 leptons, past 120 it really struggled. My present bike, well that's a little different.

Hi

Lots of things will knock top speed down. Bulky rider. Lose clothing. Down geared. Lack of power (possibly from an exhaust designed for looks / noise rather than power).

100hp is enough for a naked bike to get a bit past 140mph (but a peaky bike might need a careful choice of gearing)

All the best
