the earlier monster have a shorter subframe..
I got away without doing the 'tail chop' and I reckon it looks ok.
Of course, you will need the appropriate bits to replace the number plate holder etc..
I went this way too. A carbon beer tray dressed things up instead of the el cheapo plastic oem crap. I used dirt bike number plate parts and a stick on LED plate light for tidiness that is hidden by the lip of the beer tray. The beer tray does actually hold a beer too.
I tucked in my lights similar to Monsta, but I have oem indicators keeping me good with the local
.
Looks very oem in style, keeping the classic theme, but tidied up like it should have come from the factory.
