A quick advert for the Desmo Due series
 

Despite having an eleven meeting season ahead of us we still managed to field the following grids at the first four meetings

March 2015 Brands= 18 Entrants (should have been 20 but 2 were ruled out following crashes on the Friday test day)
April 2015 Cadwell = 24 Entrants
May 2015 Pembrey = 16 Entrants
May 2015 Snetterton = 22 Entrants

With entries averaging around £225 for a weekend meeting this equates to

Brands = £4050 (should have been £4500)
Cadwell = £5400
Pembrey = £3600
Snetterton = £4950

Any idea how much it costs to hire the circuits kev?
Because with the £255ish weekends and £120/130 test days even with my simple mathematics the amount of bike going round in all classes at setterton adds up to tens of thousands!! The endurance boys payed over £600 per team at snetteton as well!!!!
Add in garage hire transponder hire and you find it hard to see how a company can go bust especially as they get paid upfront you don't get on track without paying!!!

These days I'd expect around £30 for a weekend for some circuits, plus paying for Doctor, Medical staff, the Marshals small reimbursement, other officials etc all adds up to quite a bit
Not been many grids bigger than DD of late and some have riders doing a second class which only brings in another £40 per day
So based on an average DD grid of £4500 you would need another 6 similar grids to be looking at breaking even
