Way back in 1987 Peter Hogan , of Bantam fame , created the RCA 350cc engine . In it`s methanol burning form it churned out 44bhp .
The last of the works 125 Aprilias were good for 55bhp , so what is the connection you may ask ?
It lies in the combustion chamber , the same flat roof central plug design can be seen in both engines , The RCA ran at 8-1cr , the Aprilia
double that !
So , well done Peter , just shows what a Bantam legacy can achieve !
