Kuwi lazerlite

[balladof32]

Jamie's is a good site but I think some of the info is totally wrong , anyone have a round tubed kz84 and know they weight of the frame?

You either have a laserlite or a nova/ supernova.
As kuwahero said earlier about one tube being round and the other been ever so slightly oval. The tube are though, the same thickness.
On the nova/supernova one tube is noticeably thinner than the other.

So if your tubes are both chunky you have a kz4.

I have a kz4 and I sold a 2nd edition nova about 18 month ago. I had them both at the same time to compare.
Oh and the novas are trimolly not full chromolly.

ahhh, so from that point of view is it quite fair to say if any part of youre kuwahara frame is magnetic then its not a laserlite in any shape or form ? ...at the very least id assume its a way of weeding out the novas from the equation?

[balladof32]

haha so whos got a magnetic laserlite then ? 

[Glynnyboy]

Laserlites are full chromolly . Chromolly  is a steel based metal alloy and is magnetic due to the steel content in the equation.

The nova is Trimolly which means the main triangle of seat tube, down tube and top tube are chromolly but the rear end is mild steel. So all this frame would be magnetic too.

If the top tube is thinner than the down tube you have a nova.(both tubes are perfectly round)

If both down tube and top tube look the same thickness with one being slightly oval its a laserlite.

cool, i think that makes sense

And a supernova......?  All tubes (and forks) round?

jeez this thread has made me dizzy,im more confused than ever now

as i said earlier regardless of the year the frames must come up with similar weights, ie a kz83 an kz84 must be of v similar weight  ? surely all the models dont weigh the same due to their construction...there appears to be no genuine way whatsoever to ID them by their tubing alone. Ive read loads of info on loads of sites and there is no general rule of thumb else there wouldnt be some many ppl on forums asking ' what kuwie do i have ? ' .  jamies site is a great site but theres contradictory info there and theres nada info there to ID youre model if doubt arises. surely TT lengths have go to be a give away as again the TT lengths across the models cant be the same .

Can you put me out of my misery and put some detail pics up of what you have and just check the tubing out before my head explodes.
