TT times for road bike

[Esceptico]

Best lap times for the TT are now average above 130 mph. Anyone have an idea how quick the best guys would be on a completely stock road bike eg S1000RR (ie as you can buy it and on road tyres)?

[jjones]

Think the superstock rules since 2019 mean no engine changes so pretty much what anyone can buy in a showroom and add a few bolt on goodies to (exhaust, suspension, rearsets, tyres). You can get some pretty tasty road legal tyres but not quite full slick performance.

Michael Ritter has done various road bike tt runs in association with Performance Bike magazine. Have a google and look at the YouTube videos.

He got comfortably into the 120mph average with metzler m7rr tyres on a showroom spec gsxr. I think he went faster on a Panigale.

A really good bike, about 3/4 of an hour with me on it.

I met Jenny Tinmouth at a trade show a few years back when she was sponsered by a machine tool manufacturer, I asked her what her fastest lap was to which she replied 119...

I replied that a 119 lap was a piece of piss, I could easily do a lap in an hour and nineteen minutes

A lad I went with one year was well chuffed to hit 130mph peak over the mountain after a few familiarisation runs, (and it is indeed quite exciting with walls and headsets close by) but when I pointed out that was less than the AVERAGE for the quick guys, it really put it all in perspective!
A proper attempt on a modern super bike with a top rider, 125mph I reckon if they started from up the road at Governors and had a flying start.

Sounds about right, to get the extra 5/10mph on the average lap speed is where it gets really, really expensive/difficult. It would also be interesting to see how a bog standard bike coped with six laps? Obviously the tyres would be fubar after two laps but I'm curious as how the brakes and suspension would last.

A lot of riders use slicks on their superstock bikes for the superbike race partly due to lack of budget and partly 'cos it gets harder to use the extra power.

Even with closed roads and plenty of practice I doubt I'd go much past a 70mph lap as I've spent so long on the roads that I would be instinctively holding back in the bulit up areas.

Id be going that slow id get lost on my way round. Its hard to get your head round the average speed. On a decent 160 mile road ride I very really achieve over 50 mph average speed lol.

Is that Michael Rutter's German cousin?

The footage of James Hillier on the H2R was pretty awesome from a few years ago. No idea what time he did but he cracked 206mph.

Check Michael Rutter (Ritters English cousin) isle of man panigale on Youtube.

Stock road bike, an incredible watch.

I had a similar conversation with someone a few months ago... Would today’s stock production bikes be quicker than a WSB from 10 to 20 years ago?

That's a hole new topic that's always intrigued me.
How far would you have to go back in moto Gp for a modern super bike to match lap times and the same with WSB?

20yrs ago WSBK was still running 750 fours 1L twins so I'd put my money on a modern production bike

10yrs ago they were running 1L fours so I'd bet the WSBK would be much, much faster

At the 1987 British GP Wayne Gardner put his NSR500 on pole with a 1'38.3" lap, at the 2017 SuperStock race also at Donnington Danny Buchans best lap on a ZX10 was 1'31.9"

eta

Mick Doohans fastest lap at the 1996 British GP was 1'33.6"

I remember seeing Michael Rutter's BSB 996 being put on a dyno at a WSB wildcard meeting back in about 2000 or so and it made 148 hp at the back wheel.
You get that on a warrantied sit up and beg bike now, with panniers!

There’s so much more to it than just outright power as well. Tyres, brakes, suspension (especially on the blingy specials) mean that some road bikes are better kitted out than many race teams could have dreamed with their race bikes. One thing that won’t change is the ability of the rider to use it though. Put a road rider (as in a road licence and mainly riding roads not racing) on the latest spec road legal machinery and they still wouldn’t see which way a top racer on their bike from 10-20 years went on track / closed roads. Put the road rider on the latest spec MotoGP / WSB bike and they’d probably be even slower than they are on the road legal bike.
