dude you can fit a K&N air filter but not akropovic exhausts and power commander. these are only meant for superbikes. as they have an ECU so a power commander remaps it. rest for making your bike as a dirt bike you need to change the suspension first and there are lots of other things to be considered. i dont know much about dirt bikes. maybe other experts will help you.

btw your location says that you are from UK. where are you actually situated ?

Dude are you willing to mod it like a dirt bike??

Coming to tire, the max u can fit to Unicorn is 130 size by changing the alloys. The current 18" wheels can't accommodate 130 size tire, u gotta put 16" alloys or RIm. In front u can put 100/90.

U can put tectrac exhaust not the ones mentioned by u.

Go with NGK iridium plugs, LED tail light etc...

Even a custom paint job will do..

But never attempt to port the engine unless the person doing the job is a pro. Risk factor is very high

dirt bike eh..
first to all it is recomended that you keep the bike stock..thats the best the unicon can be...
but if you are really into the thought of modin it...
you can start by getting rid of the stock headlite..
then the front mud guard(replace with the big ones get em for quite cheap)...then the rear mud flap...
then the tyre 120chunky ones would fit the bill..dirt bikes have very large wheels to handle the bad driving conditions so downsizing the rims will not help your purpose...u could sprocket the bike for higher low end pickup..freeflow exaust and k&n along with a jet upsize....

but the point is that even after a number of mods and lots of buks spent you will soon realise that it was better as it is...

well said !!!!
