sequencial(sp) gear change for free but £££ to add to a car engine
Well not bikes exactly, but bike engined 7s?
I'm potentially looking at getting an mk indy and have been looking at engine possiblities. I've noticed that ones with bike engines are
notably more expensive as are the chassis too.
Any particular reason why?
Regards,
Andy

From a kit perspective probably just because they can get away with it
Otherwise I cant think of why you would spend the extra 
Well that didn't make much sense to me.
I can understand them maybe being more expensive as a complete car, but why would they be more expensive when building up a kit?
There's a small amount more work for reverse mounts and also the cradle for the engine but the actual chassis should be more or less the same price (just extra for the cradle??)
Bike motors are more expensive due to the bec explosion... years ago I could get motors for my bikes for buttons but now they cost lots.
Just look how cheap sub 600cc engines are compared to litre +
Fit a decent car engine and enjoy the refined(ish) cruising rpm, reliability and driveability.
If its a track car stick a bike engine in, if its going to spend 90% of its time on the road a car engine is the only way to go.
I know loads of people who fitted bike engines because its apparently the done thing, to cars they only use on the road and really quite rapidly
regretted it.

it costs more to build a BEC - the engine and Gearbox often come free with the car whereas the Bike engine can cost anything from a few hundred to a grand or so.
BEC's Can be done cheaper, but most want the best bike engines, R1's ZX12R's Busa's and ZZR1400's. hence the high prices.
It dos'nt have to be like that.
For instance, I recently put a good running Suzuki RF900R on ebay and no bids.
Start price was £100 for a 120Bhp 11500 RPM bike engine
and no one wanted it.
And that pushed my Dax to 60 not much slower than my new ZX12R engine.
There are still some older bike engines out there, which will give good performance.

I also think that generally speaking the rest of the car is more performance focused if using a bike engine to power it.
Weigh is given more priorty so generally the overall car has a better spec.
That of course does not apply to all cecs. Far from it there are some very track focused ones and some with mighty fine setup.
I guess it's the same reason you don't. See many bec robin hoods, Because if you are going to select a powerful but buzzy engine, your not
going to make it into a tourer fir example, so there are less compromises and more costs building.
Also they are in vogue, and desirable so more expensive.

because the engines are always going bang?
When you think about it why are bikes so expensive anyway.
A new R1 is, I understand, about £12k. You can get quite alot of car for that. (OK so not the same preformance but you get my point)
I was watching "twist the throttle" last week that said a bike (honda factory) takes 100 minutes to build. Not alot of labour in that
then.
I'm sure it is all about supply and demand.
I thought the same when I wad buying a BEC. I know that certain companies really aim at weight loss and handling on track chassis which cost money.
Other than that I never got an answer.
I am a BEC man at the mo so would be interesting if people come up with a sensible answer instead of the reliability cop out comment, IMO of course!!!
I don't know either. It does seem that bike engined road cars come up for sale sometimes after very short ownership / miles. For me most of my miles will be on the road so I'm not interested in a BEC. I don't think construction price is the reason as both forms can run cheap or expensive motors depending on what you choose. I know exactly where my motorcycle engine is staying - in my motorcycle.
people forget that a new R1 at twelve grand matches or beats in performance terms anyway, a car costing sixty or seventy thousand pounds. my problem
as an ex-biker was finding a way of getting a car with bikelike 0 to 60 times without spending that kind of money.... also as a side issue, kit cars
put you back into a special minority of people....

I think bike parts are more expsnsive too.
quick look on ebay shows
r1 full gasket set £ 120
zetec £ 50
crossflow £ 27
