[Bofh5]

Just for anyone planning on doing a track day there.
They do offer a 75% refund if you fail but i'd rather have a jolly up there to get checked before booking.

Dates as follows.....
25th May
1st June
20th July

The noise meter will be available 10am-12noon or 1:30-4:30pm

Only 70 odd miles from me.

No idea what the surface is like

The noise limit for the day is 105 db(A), which is measured at ½ metre from the exhaust outlet at ¾ maximum revs.

I'm hoping to go up saturday the 25th to get tested.
Its the closest track to me now apart from Thruxton but i don't think they do track days.

In our experience the following machines may NOT pass our strict limits:

Any make & model of bike with short type side silencers
Ducati 748/749/916/996/998/999, fitted with Termignoni open pipes
(but any of the above with standard pipes SHOULD pass)
Ducati 1098R
Ducati 1198
Ducati Multistrada (2011)
Ducati Panigale - all models
Honda CBR1000RR - 2008 model and 2010 modelon
Kawasaki ZX10 - 2009 and 2010 model
KTM RC8
Suzuki GSXR600 K6
Suzuki GSXR600 K7
Suzuki GSXR 750 K6
Suzuki GSXR 750 K7
Suzuki GSXR1000 K6 - 2006 model with standard exhaust
Suzuki GSXR1000 K7
Suzuki GSXR1000 K8
Triumph 675 - 2009 model (short type side can)
Yamaha R6 - 2006 model
Yamaha R6 - 2008 model (short type side can)
Yamaha R6 - 2009 model (short type side can)
Yamaha R1 - 2008 and 2009 model

105db isn't strict, that's bog standard 'loud' day.

Also, where'd you get those dates from?

They are saturdays when noise testing is available.
I think they do the track days on a wednesday.

epic fail

111 db at 10000 rpm

need to get a db killer or stock exhaust.

Poor bike didn't sound happy being revved to 10000 rpm in neutral.

Had a wander around the circuit while i was there.
Was a lotus track day which was quite entertaining.

The chicanes look harsh and there isn't any real left hand corners.
Looks pretty fast though.

The surface really isn't that bad, I did a taster up there with bike safe and couldn't fault it, they're also very good with newcomers. It is true the TT guys test up they're but I can't see any reason not to use it.

It's also true about not many left hand corners. I think they'res only a few so you've got be a bit careful with how hard u accelerate out the corners on them, I'm hoping to get up there next month.

Can i also point out that the noise testing should be done at 45deg from the exhaust outlet and not directly behind it.

The exhaust wind noise plays a factor in making it louder, it should be done as an 'ambient noise test'.

Warning - when I did a trackday there they did mixed groups (adv,inter and novice all on track at same time).

Was good fun .. but scary when Ollie Brooks (r.i.p) came past me 3 times in one session while testing his personal R1.
