Cheers, I love the HP Billet Pack!
Re zorst: Unlike the 1200, the 1250 fuels really well out of the box as standard. The mid-range from 3.5k rpm to 6k rpm is so much stronger, and it catapults the 1250. My hearing is already affected slightly in the right ear from too loud zorsts from earlier sportsbikes when younger, and I'm quite happy to recoup some beer money from my EU3 Akra which I took off the 1200 before sale. So the standard exhaust on the 1250 will stay.
I think as every newer generation comes to market, it makes a lesser argument for hilltopping.
Brilliant concept to be fair especially the self learning software.
I'd like to decat my CBthou, but by when I do the maths, £650 for headers, £350 for HT, and a few quid for odds and bits, the end doesn't justify the spend. HT recon they can squeeze another 8bhp's out of it....but tbh the 143 it's already got seems ok to me.
So agree, not much point in looking for more, especially as the manufaturers are mostly on top of the dips in the rev ranges..

Whilst Hilltop have a lot of fans and reckon that the bikes run so much better... having seen before and after dyno curves, I'm disappointed that the engineered in dip in the torque curve to get the bike through the drive-by noise test is still there. Surely it would be best to smooth it out completely?

You may even get more than you expected for the EU3 Akra as the EU4 doesn't have removable baffles and seems quite pointless imho.
I love the sound of the Akra and commute in central London so would keep it on the next bike but if you don't already these are very worthwhile. I use the 'filtered plugs'.

Had the pleasure of having this beast for a few days.
Loved it.
I think an R Nine T is definitely in the hit list.

I'm annoyed now that I can't find a clear reference.
Not only do exhausts have to meet a certain noise limit for type approval, the total noise emitted by the bike going past at a given speed/gear has to be within certain limits too.
That's why stock HD "silencers" were actually significantly quieter than they needed to be for static tests; almost welded shut (along with the intake, the fuelling, the move to quieter o-ring chains, low rolling resistance rock hard tyres and even the adoption of sealed wheel bearings) as they needed to do all they could to allow them to stay within the total moving noise envelope whilst retaining the relatively noisy air cooled engine.
Looking at virtually all dyno curves, you'll notice a dip in the torque curve that conveniently corresponds to the revs that the bike is doing at the test speed; it's engineered in to minimise the noise for the test.
The noise cameras will be very interesting as you can get a lot of bikes and cars that meet all the type approval tests perfectly but are hellish loud at high revs/speeds; meeting the letter of the rules rather than the spirit of them; the electronic valves in the exhaust can give you an almost sealed shut exhaust at low revs and a wide open one at high revs, all totally legally
Had the 500 mile service on the Triumph Street Scrambler today.
Apparently I have to keep running it in according to the instructions on the sticker on the tank; the sticker that I peeled off.
It was little use as it had a graphic of a rev counter showing where the needle should get to. Which would be fine if the bike had a rev counter to look at.
The manual is just as useless as it says not to exceed 3/4 of maximum speed, but it doesn't say if that's engine speed or road speed. But again as it says what neither maximum RPM or the top speed are it doesn't matter.
I think I'll just keep riding it normally, but hopefully in slightly less soggy conditions than today.
I'd completely agree, up to a point. I typically just try and avoid going mad for the first few hundred miles (up to the first oil change) and avoid labouring the engine always. Modern manufacturing tolerances mean that the running in procedures of the 1940's are no longer relevant, but it's best not to take the piss.
I seem to recall with my Hayabusa I had to keep it below 140mph for the first 500 miles then slowly increase up to the 1000 mile point then I didn't have to hold back. I didn't struggle to stay below 140...
BTW, I was at serious risk of doing an LTF today as the Scrambler 1200 XE looks absolutely gorgeous...
If you like bikes you will love this.
Freddie Spencer at 18,an early go pro camera,the sound of those bikes and the corkscrew.
Best watched on YouTube.
I would love a demo on the noise camera’s on my little Kr1s, at flyby speeds eg upto 70 in top its below 6K and burbling like a gud un. At aggressive riding eg 50mph in second its doing 10.5K the power valves are open its running sub 20 mpg and it sounds like any other screaming stroker. Its not Harley bleeding ears loud , but its punchy!
Ps did I mention the intake roar! Now that would be my KH 250 triple, never have I heard a bike make more noise from the carbs than the zorst!
Apologies if posted earlier

Cheers Tony. Not had the chance to do many miles yet, but smoother, faster, quicker turning, and a bewildering array of electronic gadgets! 6 weeks until I head to the south of France with mates
Only thing it needs is an akrapovic can...
Yeah, 2t's vs 4t's...no comparison noise wise. I guess the stinkwheels firing twice as often don't give them a chance.
I too had a KH250. It was on it's last legs, and as cheap as chips when I bought it. An early dynojet type mod enabled me to drop a few jet sizes. Went like a scalded cat for a short while before I holed a piston. ISTR I actually gave it away to get rid.
How will these 'noise cams' work. Usually you will be on a public road and I'd assume there will also be ambient noise, and also noise from other road users. Realistically, I can only imagine evidence being accepted in a court if the plod can demonstrate there was no one else in the vicinity at the time you were 'noised', otherwise I cant see how they can attribute a noise over x db directly to you. Unless they use a mobile type of device and wait for the noisy bikes or cars to pass then pull them up later down the road and do a test at roadside?

There are some very, very precise unidirectional mics about.
Fairly easy to target the rear of a vehicle with the help of ANPR for accurate target measurement I'd have thought.
Wileeeey interesting link thanks for posting
Steve
Mmm, i’m still not convinced on the accuracy that can be obtained. If two bikes say, are close together, one loud and the other not, how will they decide who the offender is. Also, if you have a loud can and get a ticket, whats stopping you from fitting a quieter one and saying it was the car/bike a few yards away, or another road user. I get directional mics, I use them when filming to mask unwanted sound, they work reasonably well, but certainly not point and shoot accuracy. Anyways, time will tell I suppose.

I could see it working if the camera identified a potential loud vehicle, and the police then paid the registered keeper a visit to inspect the exhaust for the BS stamp (or whatever it is these days) or signs of tampering, but I can't see them having the police effort spare to do that when they're not able to investigate burglaries etc
Perhaps it just flags the number plate for next time the driver passes an ANPR car (off the throttle and clutch in) so the police can pull him over?
I do agree it is difficult to enforce even if get the right vehicle as I used to have a bike with open carbs that would probably have failed a noise test on induction noise alone.
That said the number of ridiculously noisy cars and bikes I see (mostly high end) might well be stopped / reduced if they fear a ticket or can't simply flick a switch when needed to quieten it down.
ooo, a bike thread. Didn't see this before .
Ive got 4 tucked away in my workshop.
An early GSXR1100 slabside that is in the line for a complete referb
My so called daily ride , a Ducati Hyperstrada that in truth hasn't been out this year
A Ducati 1098 R which being that model is a total animal to ride
A Yamaha OW01 which is race spec and has just been rebuilt .
Never get around to riding them nowadays
Noise cameras. Another reason to live somewhere else.... don’t recon I’ll stay in the UK much longer.

Latest arrival, another Bonneville T120.
My second T120 (another one of those on the list of 'bikes I regretted selling') and it'll nicely fill the gap between sports bike and trail bike, as well as providing a 2-up tourer.

Ignorance breeds Fear. Fear breeds Hatred. Hatred breeds Ignorance. Break the chain.
Placed a deposit on this bad boy yesterday at a specialist dealer near to me.
It’s a 1995 R1100GS with 9,000 miles on the clock. To be honest it looks brand new. I’ve been hankering after a nice oil head GS since I got my R9T and I’ve paid a premium for the unbelievable condition of this.
Now I just need to decide whether to liquidate some watches, the R9T or keep everything. There’s just enough room in the garage!
