The mock up:

This Sportster was  built as a tribute to Vincent Egli.

Dash panel is a mix of

fiber carbon and aluminium,

instruments are stock.

 Oil tank is relocated under seat. Rear sub-frame under seat was made from stainless steel and titanium.  Ohlins shocks, 1.2 in longer than standard complete the job

I design this forward mounted 90° air intake system in 1992  when no equivalent systems were available on the market.
