Gonna get some Carbon-Ceramic brakes? That's gotta be worth a couple of pounds.

When I weighed a bunch of conventional forks a few months ago FZR400 were the lightest by quite a margin and with an alloy stem and/or alloy bottom clamp, they could be even lighter. I have a modified GSXR stem in a set of RD350 forks on the drag bike.  That saved a bit.

Might be worth looking at a modern small bike for even lighter/stiffer forks.

i was actually talking about this 2 nights ago. I will probably go with an aluminum stem and a billet lower tree eventually, but im keeping the stock forks, they work very well with the setup and emulators in them. I mean, im over 100 lbs lighter as it is.  :whistle: if i can hit in the high 220s/low 230s i'd be blown away. (im in the 238 ish range i think, maybe less with fuel) after the axles i'm going to weigh it on a certified scale.

Mark, which speedo did you opt for?
Frame band swingarm is a masterpiece.

thanks, Danny did a hell of a job on that frame.

I used a trail tech endurance. some of the models can be powered by AC voltage, or DC. I needed that because all the power on that bike is AC, because, wiring and junk is heavy.  its really good, and it automatically backlights when the bike runs.

interestingly, this jut got posted on FB by allen tucker. hadnt seen this pic before, but the yellow bike in the pic was basically 'V1" of the lightweight bike , a modded stock frame i built out of spares. I think it was about 35-40 lbs lighter than than a stocker. left to right: cody, me, pete. 2010

Hi Mark,
who was the manufacturer of the fuel tank on the yellow bike? I have exactly the same lying around for years.
Regards Uwe

i dont know. i got it with a bunch or parts years ago, was relatively heavy fiberglass unit. neat tank though. Lined it and never had an issue. Made a strap to mount it though, was kind of a PIA.

Yes, it is quite heavy for a fibreglass one. But as you said a neat tank. I like it. But more an item for the shelf for me. I have a few alloy tanks lying around if I intend to do a build of another bike
