This " a better track weapon=better street use (and I'm including, even emphasising the knarlist conditions the street offers up) is a fallacy.
If it clarifies my opinion, I take the highest performance/most easily altered to the street package bike that is for sale at the time I'm shopping. Then I make the alterations to get the suspension and riding stance, and luggage on that highest performance bike, so i can max appreciate it where I ride it.
What has been developed from racing, is Golden, for the most part. That's where the light, trim, stable, super suspended, reliable, controled bikes came from, and the race replica's sold in volumes, to allow the price to the customer to be the bargain of a lifetime.
For some un-explainable reason, street use bikers, fail to grasp the difference between the closed course race track and the street.
Throttle (use of power) is entirely different on the closed course track that is both a surface that is designed and maintained for racing safely and everyone is going the same direction and got a racing license to be there.
What works best on the public street/road/highway, and what works best on the track....is two different things.
The sooner a bike rider grasps that, and the finer parts of the skills that relate to surviving on the street...the higher the odds are that the bike rider will ride safe and sound, for their whole bike riding life.
Back to the characteristics of the First Gen ZX-10's (and this will greatly depend on how the rider uses it) The bike is exacty the type that works best for me, in the tight/steep twisties. Like an open class dirt bike on steroids.
Here is an account of my ride over Ebbetts pass yesterday. I'm not a skilled writer, so ... I know I won't paint the picture, as clear as a rider being there, but here goes.
Hwy 4 is very clean now, the spots with fallen rocks and gravel washed over the road with the massive runoffs crossing the road are very few and no problen to deal with.
The Water over the road starts in spots, at Lake Alpine, and the biggest thing is being super cautious when approaching a blind corner, because when the water comes into view there, the far side is still in the blind end of the corner, and you don't know how far it is going to continue, or just how sharp the corner will get. No place to do additional braking.
There were other spots that became shallow ponds where water filled dips (whole wideth of the road) but none were above the axle and they were all in straight road spots, so no biggie, just go slow to keep the the wake and splash from being more of a problem.
One really fun spot, was where Cal-Trans was dong something, road work wise. Instead of the usual stop traffic (not like there is traffic but some word must be used for someone using the road) then letting traffic go in alternate dirctions...they directed the road users to go over the bank (not much of a bank at all), into and through the trees, for about 3/4ths a city block length, and then back onto the road.
I was the only Race replica Sport bike up there. And The conversion I did to mine, with flat tracker bend handle bars, Scotts Damper, and Race Tech conversion front and back, to Shim stacks/Gold valves more akin to off road bikes, and my removed lower plastic, all was in it's glory at that moment.
By glory, that glory isn't confined to events like that, The glory extends to every moment or event in the ride. No computer management, I'm calling the shots, on the controls
You laughed in his face, right? 
The only difference between BST's "street" and "race" wheels, are that the latter have magnesium hubs instead of aluminum. I've seen a trackbike that took a long hard tumble into the desert wastelands that surround Willow Springs. The BST's were just scratched up a little but were intact. On the other hand, the front magnesium wheel on a buddy's R1 got a really bad ding in the lip on a Berryessa run, good thing that it retained air. At least mag rims can have minor damage pressed out, but the operator better know what he's doing. I don't know how many miles Doug has on his set of BST's but I bet it's way more than 10,000.
