Japanese Vtwin Sportsbike anyone?

[northwind]

I'm more interested in what Aprilia are going to do with their new wee-twin to be honest... But then I wish the Japs would do some proper updated IL4 400s as well benefitting from modern weight saving and engine efficiency. That's an IL4 I'd buy

TL from Hell? Not quite what we were speaking of, yet never the less...

Shows what you know.

KTM RC-8 VENOM....

But what do we know, we're only the potential customer

Agree 100%. A Japanese out and out sport 750 V-Twin, to compete with the Ducati 749 would be ideal. Sort of like a 'ready out of the box' version of JHS racing's tricked up & bored out SV650.

Sadly I don't think Suzuki would do it (not different enough to the SV650 and the cost would probably be the same/more than the SV1000). Maybe Kawasaki to do it with tuned SV650 engine? I can imagine a hell of a lot of SV owners looking to move to a bigger/sportier bike would want one, as well as it tempting people away from ss600s, as you say.

Apart from the engine deveopment, most of which has been done by the likes of JHS and a few others, the costs would not be that prohibitive as they already have the running gear in the current GSXR models. I love my Gixer, but if I could have my SS600 performance from a V-twin with the same handling I know which one I'd prefer, and it wouldn't have 4 cylinders....

The SV1000 is not an out an out sports bike, it's a big V-twin intended to try and catch the old TL owners, and those with Firestorms & Falco's, both of which are past their sell by date.

Do you know of anyone who has shoehorned a tuned SV650 engine into a sportsbike chassis? I've heard of things like a TL1000 engine in a modified SV650 frame, but presumably it'd be harder to fit a twin into an entirely differently shaped IL4 frame? Be interesting to see if anyone has done a 'prototype' one that you could get one of the big 4 to use as inspiration.

the question I would like to ask is why? its far easier to fit gsxr usd forks with radial calipers to your sv frame than it is to fit an sv lump into a gsxr chasis. The mods that you can do to the sv nowdays are rdiculous! The frame is plenty stiff enough its just the suspension and brakes let it down. The swingarm doesnot really need to be braced does it? and you really dont need a 180 rear tyre even if you tune the engine! my thundercat has more bhp than an sv and that uses a 160!

Agree totally.
IL4 frames are not a good starting point for a v-twin as they are quite wide (something about filling a short IL4 engine ) Far better to start with a frame designed for the job and pick up better peripherals to uprate the bike, I considered this when looking at the kwak, but decided it would be too expensive for what I wanted.

Fair comment, as long as the radial master cylinder and shock came with it. You then have to think about suitable fairing, the GSXR range already have it.

well master cylinder yes but shock no, If you are putting a front end on the bike that is worth £1500 you might as well get an ohlins rear unit!

again not really, the sv fairing is enough, you do not really need bother converting a gsxr fairing to fit, but then again it would be down to the person doing the conversion. If it were me? I would get sv race fairing and make it road going!
