Hi all,
Does anyone know the noise db level for the Aprilia racing titanium exhausts? Have just had them fitted and they sound awesome but my concern is I have booked a trackday at Cadwell next week and wondered whether they would be okay for the 105db limit.:dunno

Also, this is my first trackday and any tips or advice would be welcome.
 
first advice is relax.

i did one on friday at anglesey on a hire bike and they're awesome. they never get boring. Cadwell is a great track tho but charlies 2 and the mountain can be daunting at first.

Make you sure you ask various people what's going on when you get there.

Obviouly not knowing how fast you ride bu make sure you get a lot of heat into your tyres before you start giving it some.

What tyres are you running
 
I'm running Pirelli Diablo Corsa's, not had them on long but are well scrubbed in now and have been happy with them so far.
 
Sweet. ahve fun dude. you'll love it.

When i do a new track i usually spend the morning 3 sessions learning it. then afternoon i go nuts. You have picked a hard track for your first one tho. take it easy. askt eh instructors to follow you around. If you're going with hottrax speak to Nige. He's and instructor and rides a race Hornet. Don;t laugh, I've seen him embarrass many thou's on that thing.
 
Thanks for the advice mate, appreciate it. Will let you know how I get on and hopefully post some pics
 
Nice one. One other thing to be carefull of mate are the photographers. They cost a bomb but I'm as guilty as the next man as there's usually at least one good shot which will be on my phone, facebook, MSN etc. £30 is a lot of brass for 20 or so photos.

Look what the *******s took of me:

howdy fella as for the exhausts i also have aprilia race cans on, and mine were 102 db when tested at oulton park last year but may differ depending on how used they are will get louder with age....:devious
 
Milliemonkey,
Nice photo mate, was that from your recent outing at Anglessey?

Carpe,
Thanks for the info, the cans are fairly new so, fingers crossed, should be okay.
 
adjust your tyre pressures mate! I did my first last year on my previous bike (daytona 675) and we all got advised to adjust our pressures to 30 f and 33 r (cold). It'll give you a bigger foot print and as they will be running a lot hotter the presure will increase
 
Have a read here mate, this will help i am sure:thumbup

If you take some steel wool and shove it up the cans it will help deaden the noise, if you fail they will send you back to sort them out and come back to re take the noise test, they might pass but i reckon they will be close to 103 to 105db


What do I need on the day?

The absolute basics are licence, bike, helmet (to ACU/British standard), gloves, boots, and one or two-piece (zipped) leathers. I also consider a back protector as an essential.
If you have sparky sliders (knee/toe) replace them with standard ones as you will be told sparkies are not allowed during your briefing. Take your mobile phone and some cash. The mobile to phone someone if necessary (if only to share the excitement!) and the cash to buy drinks, food, fuel and spares if necessary.

If riding to the track – then take a small rucksack or bag on the bike if you can. Ideally you want to take basic tools Eg. allen keys/ spanners to take mirrors off, zip ties and gaffa tape, water, a couple of butties, fruit, crisps and a chocolate bar or two. To keep energy and concentration levels up it’s a good idea to eat and drink regularly thoughout the day rather than waiting until lunch and then eating a lot. If you cant take tools or are unsure what to take don’t worry as there will be plenty of people at the track prepared to let you use their tools if you ask nicely. (If you go on a day where a few of us off Throttlemonkeys are going then meet up and use our tools and store bags and valuables in our car/van).

If you are taking your bike on a trailer or in a van then prepare a check list of everything you need as theres nothing worse than getting there and finding you have left something you need.


Do you need a licence on a trackday?

Best principle is YES. Take your driving licence with you. (Both parts for the newer versions). If you do turn up without it the TDO (Track Day Organisor) will phone the DVLA on your behalf usually for a small charge of around £5. This can only be done on a weekday and you will lose any tracktime until this has been done.


Do I need to do anything to my bike for the track?

Yes and no. Whilst you are not obligated to do anything it makes sense to look at a few areas:

1) Your bike will be working MUCH harder than on the road. Check tyres. Make sure they are upto the job (enough trad and good overall condition). If your bike hasn’t been serviced for a while its worth considering a service or at least an oil and filter change. Check brake pads and make sure they have plenty of meat on them. Have a general check over and make sure bolts are tight, chain is lubed and nothing is ‘hanging off’. Also make sure your exhaust is legal if your chosen day is a ‘quiet 98db’ day. If it’s a normal day (104db) this is not usually an issue.

2) If riding to the circuit – Before going out on track remove or tape up your mirrors as you don't need them and they will be a distraction. Its also a good idea to put tape over the speedo (not rev counter) as again you don’t want to be looking at your speed. Its also worth taping up indicators and lights ‘just incase’ (if you are unfortunate and have an off it stops glass on track).
Some people remove or tape up their numberplates. Its personal but it has been reported in the past that insurance companies have had representatives there (or looking at photos afterwards) making a note of registration numbers should a claim be made on or near a trackday.

3) Reduce your tyre pressures from road settings to about 30 front and 30 rear. If unsure ask the tyre man or one of the instructors. Tyres will be running much hotter on track so this drop in pressure will allow them to work more efficiently. *REMEMBER to put them back to road pressure if you have to ride home*. (If you don’t have a pump – just ask as there will be plenty of folk that will let you use one).

You can buy track bodywork and crash bungs for your bike. Fitting these is a very good idea if you intend doing a few days (or buying older panels which can be swapped over). The bungs can be useful for road riding aswell but if fitting track bodywork bear in mind that it will not have cut outs for the lights.


How is the day organised?

You can usually sign on from around 7.30am. You just need to fill in disclaimers and liability forms (or present them if you have done that in advance) and collect your wrist band (which gets checked before heading onto the track). Briefing is usually around 8.30ish. This is compulsory and you will get a card, sticker or second wristband (depending on TDO) to show you have attended. If you miss this you cannot go on track until you have attended a later briefing.

The briefing will cover what is expected of you on track, the order the groups are out, warm up laps and last lap passing policy, flags/ marshals, ordering photographs and use of instructors amongst other things. (Each TDO has their own briefing format). The briefing usually takes 20 to 30 mins and Novice group are sometimes asked to stay back for a few additional pointers.

There will be three groups - novice, intermediate and fast. If its your first trackday its best to start in Novice. The organisor will be happy to move you up if you are finding the pace too sedate. Likewise if you book straight in the Fast group and aren’t upto the pace they will move you down. The key is to be honest with yourself when you book – accepting that if you are not experienced with trackdays you have a whole new learning curve to go through. Not only do you have to learn the circuit but your riding style in relation to the road will develop very differently aswell.
The groups will be annouced over the circuit PA system. Some TDOs also use flags – a different colour for each group.

Sessions are normally 20 minutes per group which means that you'll get 40 minutes break in between. Lunch is usually around 12.30 to 1.00pm for one hour. Sessions then continue until around 5pm dependant on light. It is fairly normal to get six sessions and sometimes seven sessions in a day. The number can depend on stoppages though so nothing is guaranteed.


What else is available to me on the day?

Instructors. You will be told where to ask for some time with an instructor in the morning briefing. Its free and very worthwhile. The instructor will follow you round, watch your lines. He will then pass you and let you follow his lines. (This is why some instructors leave their mirrors on – so they can see ‘pupils’ behind them). Once the session is over you can find the instructor and get his advice on your riding and lines.

There will usually be a tyre man at the circuit (although this isn’t guaranteed so worth checking beforehand if you are likely to need their services). They will supply tyres, swap your tyres over if you have spares or wets and will (if you ask nicely) alter your pressures if you do not have a pump.

Suspension services are now becoming more available where you can get your bike set to base settings and then to your specific weight and riding style with adjustments throughout the day. This is usually around £45.

There will be a photographer. Some require payment up front in the morning and others will take payment on the day or afterward (off a website). Prices are usually around £7 for a single photo and upto £35 for a disc with a dozen or more pictures.


Will food/ drink be available?

Yes. Larger circuits have canteens and smaller have burger vans. If you haven’t been able to bring plenty of water and food for the day then you will be able to buy at the circuit but as ever be prepared to pay over the odds. Remember to drink plenty to keep hydrated and eat small and often to keep concentration levels up


Will there be fuel available onsite?

Some circuits have fuel on site which opens at lunch time. Be warned its usually expensive but not often available. Best policy (if you cannot take spare fuel) is to fill the tank near the circuit on the way there and then pop out at lunch time and re-fill if you need to. There is asually a petrol station within a few miles form the circuit and the TDO will be able to give you clear directions. If you do go out for fuel remember to re-attach number plate or take tape off if taped up (and mirrors if you need them).


Will the day get stopped if the weather is bad?

No. Not unless the circuit stops the day (not the TDO) which will only happen very rarely. If its raining just take it very easy and concentrate on smooth throttle control and smooth lines – Or sit in a dry garage until it stops!!
Even if you take the cancellation insurance some companies offer this is null an void if they get you on the circuit for even part of a session so is not really worth it. (Just my opinion there).
If a days is cut short because of weather then generally that’s it. No refunds.



The main thing about doing trackdays is to go there and enjoy it. If you can go with mates - or meet up with folk at the track I find that does add a bit of fun to the day with the craic and banter. You can also borrow and lend stuff that way!
From a riding perspective just go and take it easy whilst you get a feel for the circuit and prepare to be amazed at how good your bike is! You will be told during the briefing that its not a race and thats exactly right. Whether you are the fastest or slowest out there - ride within YOUR limits and enjoy it. You will find as you settle down you will feel you are improving and going faster each session and with confidence can start to extend your personal limits.
 
Amazing write up Badger, thanks for that mate, much appreciated!

Superted, there on 7th May mate, if you get the chance to get over come and say hi, be good to meet ya. You'll find me easily enough mate, will be on the loudest ape bringing up the rear in the novice group!!
 
bringing up the rear in the novice group!!

We've all been there mate. Me especially! I'm only up to inters now. Tried a brief spell in the fast group once and just got swallowed by everything bigger, newer and faster.

I cry myself to sleep sometimes wondering if i'll ever be fast.:down
 
i did a noise test on the standard can and then the RSV titanium with a proper noise test meter. At .5m away at 45 degrees down from the end of the pipe, i got 82dBand 95dB respectivley. I seem to remember at Cadwell your asked to rev to 4000rpm whilst they take a reading before they let you on? i think the noise intensity increases by the square for each increase in dB. 95db is starting to get loud. From 82dB you should be starting to think about wearing hearing protection. Just try to ride faster to try and outrun the noise:devious.

Track days are good and you'll enjoy yersen. MAKE SURE YOU WARM THE TYRES UP WITH 2-3 LAPS. Follow Badgers words and you can't go far wrong.

I min't pop-up to have a look if its nice weather.

are you doing a full day or evening session?
 
Get off this forum and get that bike finished. then take it up to Cadwell and un-finish it. :thumbup If you go then i'll no doubt see you there
 
Am on it, too late now, will play tomoro, will take the 250 on track, the rsv is staying forever, you`ll know that when you catch up :nana
 
i live near Lincoln. Superted lives in an upside down old caravan parked in a lay-by.:nana whats the 250? seriously about half hour away and its a pleasent run up to Cadwell if the suns out.
