Best starter bike to customise

Mine is a 2006 marauder k6 carb variant and it's so easy to work on it could be disassembled and remade by an infant, I've replaced the exhaust with one from a gsxr1200 hayabusa and it sounds even better with the gunshot kickback, ever since I've gotten it I've fallen in love with every aspect with it, incredibly stable and reliable ride, picks up very well for a 125 but engine output is limited to 65mph at a stretch, parts are relatively cheap to replace which I found out after having to replace a punctured carb diaphragm after riding it home 19 miles at 20mph but not a problem with it since then, if your looking for a starter cruiser i fully reccomend this bike as its just too good to be true, I'm always thinking I wish I had this bike when I was a teenager then I remember I've had it 2 years and I'm 19, extremely reliable aswell with mine averaging 85mpg, around 90 at low revs.

Love the bike, love everything about its simplicity and beauty, my only regret is that it wasn't my 1st
