Actually your wrong, the popular belief is that this ceased being prototype racing with the introduction of the Single Tyre rule, the Tyre supply limit rule, the Fuel limit rule and the Engine number limit rule......
The Competition in Motogp has become all about how well a manufacturer can build and compete with a race bike under extremely strict regulations, with a retail selection of Rubber from 1 maker.
The term Prototype is as follows;
'A prototype is an early sample or model built to test a concept or process or to act as a thing to be replicated or learned from'
It seems almost impossible to find any similarities between current 800cc motogp racing and this definition......
Anyhow it is what it is, lets just hope for major changes when this graceless 800cc era finally passes.....
I am aware of the limitations and don't like them. What your post implied though was that you wanted to standardise the lot. I take strong exception to that notion.
