    thanks man, they are based on these concept bikes:

    KTM is now making this bike under the name 125 duke, but it’s not quite as pimp as the concept bikes.

    I think I’d go for the bottom one – little bit unfinished though. should’ve at least tried to slap something like a lamp onto that thing :)

    @ Patrick, the top one is the finished version of the bottom one, which was just a version I saved along the way and liked too so figured it was worth posting. Kind of shows why bikes nowadays always end up so busy. To make the bottom simple version took me about 15 mins, and the top one an hour or so. If I spent as long on it as is normally spent designing bike it would start getting busier and busier most likely, which is what most new bikes end up like.

    I realise this post is a few years old but if the designer of this concept bike is reading this is there any way you could design a few more pictures of the bike from different angles please? I have a 125 duke that I’m seriously considering turning into this bike and a few more pictures would really help!
