This is based on a over priced Italian (superbike) of questionable build quality and reliabilty. it seems to me they have chosen the mechanicals looking for exclusivity rather than suitabillty.Surely it would have been better to have used a bike engine from one or the japanese manufacturers imo .

Of course if they had used a Japanese bike engine people would be complaining that it was boring and didn't have enough character, why couldn't they have used a Ducati motor instead.Its like the people (mainly journos) who complained about the early rally-reps being too hardcore and low-rent inside, then once they changed that the same people switched to saying they'd become too soft and heavy and the early ones were the best.
You can't please everyone!

I would like to see a full on side view. There isn't even one on the website.
If you think about the overall length of the V-twin, with its front cylinder sticking out, and add on the length of a chain drive diff you end up with quite a distance between the rear bulkhead and the rear axle line.
The car looks stunning in all the views offered but might not look quite so well proportioned from the side.
Revese gear isn't mentioned either. Presumably you get one but the Drexler diff specified doesn't give you reverse, unlike some more bulky chain drive diffs eg. Muffet.
I've built a bike engined trackday car using lightweight bike shocks and titanium exhaust system, ACB10 tyres, titanium paddleshift, etc... albeit with a full cage, and had a target figure of 425 kgs.
I recently sold a very lightweight chassis for a bike engined kit car that weighed 30 kilos bare. No cage, no suspension mounts and in need of some extra bracing. We had intended to build this up in a very lightweight fashion with a target of 350 kgs which many said would be very difficult to achieve.
If the Spartan comes in at 300kgs, ready to run, then I take my hat off to them.

or if the engine is longitudinally installed with the out put straight on to a differential you get very compact packaging ceebmoj said:

It probably won't be ready to run, but it's probably the dry weight. That's the case with most bikes if I'm correct, not sure about cars.If you think about the overall length of the V-twin, with its front cylinder sticking out, and add on the length of a chain drive diff you end up with quite a distance between the rear bulkhead and the rear axle line.

That looks lovely!
Pricey, but then it is hand-built (probably) with low volumes and expensive materials.
I would have one in a heart beat at 500kg and road legal. As much as I like 7's, I would prefer something mid-engined and with full bodywork!

my thoughts exactly. beautiful. how much does a track spec radical weigh?Pricey, but then it is hand-built (probably) with low volumes and expensive materials.
