Unsure how well this business is known in the UK so just a mention. Whilst I'm happy with the 70mm system and termi's on my bike something to stand out from the pack would be nice like this titanium system: This is from http://www.stradafab.net/ See their site for lots of Ti lovely frames and other goodies (and no I have no interest in their business).
Frames look nice - strange they picked the Sport Classic to do first - a 996 or 999 frame might have sold better, even an 848 / 1098
They did a ti frame for an s4rs years ago. If interested have a look on www.bellissimoto.com On one of their project bikes. It was given away in a competition. Had some cool trick bits on.
I don't have any particular expertise in this area. I know it was used for the con rods in the RC30 and Ducati have used it for same in Panigale R iterations.It's also in widespread use for valves. Obviously it's extremely pricey so, just as someone may not "need" a CF swingarm for example, doesn't stop them from wanting and getting one if they have the means. I think the products of this business probably fall into the same category.
