Hi guys.

I'm looking to add a modern twist/modify my k1. My ideas so far are:

-replace the k1 front end with something a little newer k4 onwards
-Replace the swingarm, maybe a black braced swingarm or a single sided swingarm, not too sure about that though
-I like the idea of an underseat exhaust
-Colour change from yellow/black too vinyl wrapped carbon or carbon dip with race decals, moto GP test bike style.
-k4 or later rear sub-frame and seat unit

I realise the cost, time and engineering that will have to go into these mods, so, with a new baby in the house, it's going to be a long term project.

Any thoughts or ideas welcome.

tlr1000 front end is a bolt in replacement and far cheaper than K4-5, but you need different brakes or a mount made up.
k1-3 750 swingarm is a straight swop.
be cheaper to buy a 750 imo
