Carbon Fibre Wheels. Insane project.

Cabon wheels make a **** load of difference to any bike. Its all about removing 'unsprung weight'
My mates R6 is mint with them on. I've had a go on it with stock wheels and the carbon ones and it flies in and out of corners with ease. Some bike mag types reckon you could knock 2 secs off a lap with this modifiaction. now that is a massive amount of time!!!
The only down side is its very flighty over crests and lifts the front easily. This could be a problem with the SV as its torquey.
Good luck and hope to see some pics of the transformation soon

what is it about the SV that will prevent you losing your life or your licence more so than a 600SS? Ignoring the 600SS is better because..... discussions. The SV hardly places you in the riding sedately bracket.

Well, I have a BST front wheel on order for my pointy, so I guess I'm insane My reasoning was about the same as yours... plus I like building and fiddling, so it's win-win.
It will fit into the K4 GSXR600 forks with matris 25mm cartridges which I've further modified and re-valved. I have a WP4618 shock from a GSXR, with a custom linkage. There are also curvy intake cams in place of the exhaust cams, a LeoVinci full system and... 46mm de-restricted Ducati 748 throttle bodies. Plus a bunch of other stuff. With the BST, total weight with an empty tank will be 154kg (including road gear).

The rear wheel is trickier. I have a ZX6R wheel, because it was easier to modify the cush drive to narrow the chain-line. TWF now do a kit for the 2006+ GSXR wheel. The question is, how much is it possible to do this on an after-market wheel like a BST?

In total, the chain line is off by 7mm. Flipping a front 520 sprocket and putting a 2.4mm washer behing it, you can move the chain out 4mm, but that's about the limit. You can run with the alignment off by a mm or so without grief (as I found out due to sloppy measurements ).

So at a minimum, you need to move the sprocket in 2mm, ideally 3. Certainly if you can get someone to mill your sprocket, taking out 2mm should be ok (but a 520 sprocket is only 6.3mm thick...). I'd be surprised if you couldn't shave 1-2mm out of the cush set-up on a BST.

I'm holding off ordering a rear until I get some machine shop facilities set up in the new house

A fair bit less power. Fat midrange for getting out of corners rather than carrying 10k rpm mid corner. And for mine, it's naked (except for a little Ducati Monster bikini). I raced a 600 and rode one on the road and somehow they just encourage you to go stupidly fast. The SV is heaps of fun at lower speeds. It is of course still capable of going stupid-fast.

Erm I think you left out one bike which fits your description

Aprilia RS250

Mine was a toss up between the SV and the RS, the only reason the SV won was because I use the SV to commute on a nice day and generally I dont like to play pretend motogp racers at 6.30am!

Or, what about the ZXR400, RVF400 or dare I say it an RS125? I had 4 RS125's, very tunable and quicker in the twisties than my mate on a 600, yeah might get blasted on the straights but theres no skill in winding a throttle open!

Also why dont you just put a 14 tooth sprocket on the front?!, Ok no better handling, but quicker to accelerate!

Anyways keep a running thread open of the mods you make, should make an interesting read!

125s... meh, alright for very twisty roads but no good for say going to the other end of the country to try the twisties there.

Journalist friend who raced a TZ125 did a road test on the RS125: reckoned it would be easier to keep his license on a 'busa. The problem with the 125 was that you had to ride it flat-out, all the time, to have any fun

Yeah, rode an RGV250 on the road for a few years. Definitely good fun in the twisties, but thirsty, unhappy on any sort of freeway and a nasty maintenance schedule.
