You can get modified front mudguard, add a wind-shield if you want to, even fairings like those on sport bikes can be found but I would not recommend that because your bike is air cooled and if you add fairings flow of air to engine will be blocked.
Somewhere during the last year a member here posted some pics with alloy rims on a Deluxe, so that's also an option. Modified muffler can be added for cool looks and a bard hoarse sound if you like louder bikes. Modified steering, indicators, blah blah blah can be added to customize the bike, it all depends on what you can find, afford and what you want your bike to look like, that is to say, a quingqi "Chingchi" is also a form of bike.
Good lcuk.
