You and me both. I am curious how much my HP4 weighs after stripping it down to be a track bike...

@dagor6 had some pics of a frame with parts of it cut out to reduce weight. Not saying that's how this bike achieved weight loss. I'll see if I can find it.

I guess titanium, lighter uppers, 520 conversion, and lighter wheels will drop some weight.

1. All street-related, stock components were removed: all stock lights, fairings and controls, ABS pump, ignition, stock harness, radiator fan and shroud, kickstand, some brackets holding this stuff.

2. Lighter components installed: ultralite racing fairings, magnesium wheels, 520 chain, Ballistix lithium battery, aluminum sprocket, upper triple tree, rearsets, full titanium exhaust, Brembo brake master cylinder, clip-ons, etc.

3. I am not sure about weight differences: STM clutch, billet camshafts, Ohlins suspension, linkage, pivots.

4. The bike works out regularly staying lean

Hope that helps you with your weight reduction agenda.

To elaborate, to save weight replace only STEEL parts with Ti parts, as aluminum is actually lighter than Ti.
https://titaniumprocessingcenter.com...m-vs-aluminum/

Although, there may be some instances where you can actually make a Ti part a little lighter than an aluminum part because you need a certain amount of strength or stiffness, but it'll take a lot of analysis to determine that. For reference, we make everything out of 6061-t6 aluminum to save weight....unless we need something stronger, then we use 7075, which weighs the same but is stronger (point at which it will fail - but it is no stiffer). If we need to get stronger or stiffer, we'll go to Ti. If that doesn't work we'll go to stainless or some exotic alloy, or C/F.

I USED to think Ti was lighter as most people do as well.....

Bottom line: Don't go to Ti from aluminum to save weight.
