1. To build a road legal factory racer- the highest performance motorcycle that could still be ridden to the corner shop for a loaf of bread.
2. To build a unique machine but still with worldwide parts availability - this has been achieved by utilising wearing parts from existing motorcycles where it didn't compromise rule #1.
3. To allow ease of maintenance either at home or at the track. Both the heads, the clutch, the gearbox, the alternator and the waterpump can all be removed with the engine still in the frame -the last four don't even require the removal of any bodywork.

The decision to use the cylinder head from an existing 4 cylinder engine was one of the few times that economic reality overruled engineering innovation. There is little chance of selling a hand built special (particularly overseas) if the buyer has no chance of buying spare parts in the event of Drysdale Motorcycles ceasing to produce the 750-V8 for any reason. Most of the critical wearing parts in the 750-V8 can be purchased through any motorcycle dealership - guaranteeing worldwide parts availability. 

Ian has no illusions about the economics of motorcycle production - even at the estimated price of AU$70,000 ( US$50,000 ) he still intends to build minimum batch runs of 5 or 6 at a time to make the venture profitable. He has managed to run a successful engineering business for 10 years with its ups and downs - and still find enough spare time ( and funds ) to develop several radical motorcycles. 

The demand for 'upmarket' motorcycles worldwide is extremely strong with buyers willing to pay a premium for individuality and high performance - in these two areas the Drysdale 750-V8 will be unsurpassed.
