Well there are few parts that's been changed, starting from the front
effectively its a GasGas front end :-
40mm Marzocchi Aluminium forks , GasGas Head-stock , Front wheel & Braktec Caliper
Fitted a Raga Reed block and Carbon Tech Reeds & 28mm keihin carburetor,
Stainless Steel front pipe,
The tail pipe is carbon fibre [ my own design ] using the longer straight baffle tube
[ 8 layers of Prepreg Carbon fibre layed up in a split mould ] using the original end caps ]
the rear shock has been replaced with a GG18330 Gold Ohlins shock & CSP Suspension Plates
and most of the fixings has been replaced with Titanium Fixings.
There's probably more things that have been done, but these are the highlights.
