havent posted for a while but have been thinking about a motor bike engine in my 64' mini (ala aussie racers)

just wondering if it has been done and how successfully.

Cheers

I have an R1 fitted into a mini front subframe, but mounted in a spaceframe hillclimb special

Lots of Bike engines in Mini grass-track racers in England & there are a couple of companys over there who produce a "Kit" (so to speak)

The best one to fit would probably be to Yamaha R1 engines as it has it`s gearbox "up-ended" (for want of a better description,,, therfore it`s the shortest engine lay-out you can get (pretty well) Unless you wanted a smaller capacity engine like an R6 (Why would you tho?)

Otherwise if it`s just for racing on the track & you`d rather have bucket loads of traction,,, then stuff 2x of them in the back driving through a common axle

TheMiniMan - Could you post some pics of how you've mated the bike gearbox to the drive wheels. I can never see enough of these systems because I'm planning on doing one myself in the future. Could you please send me some high res photos to my email? Thanks [email protected]

I have a few shoddy pics,,, only crappy ph camera & i`m terrible at taking pics at the best of times,,, But i have recently aquired a Quaife Limited slip diff for it, so ,,, soon i will be swapping it over for the std one & that`s when i`ll take some "Decent" pics ok?

sorry, but i have no idea when "Soon" will be tho,,, maybe a couple of months,,,, can you wait that long?

TheMiniMan - I can wait, I'll still be working on my Travelle"R" anyway. Whenever you get around to it is fine.

Hey Matt,

I think the Hayabusa would be a better bet for a bike-engined powered brick! Just for the simple reason the gearbox is stronger to take the added torque of the 'Busa engine.

Not as compact as the R1, but better suited reliability wise to hauling around something that would be considerably heavier than the original bike it was intended to power.

Also, the Z1300 Kwaka donk is worth taking a look at.

My $0.02

Cheers,
Tricky

Yeah Tricky, i totally agree,,, espcially for a rear mounted version

The problem with front mount is lack of room/space, hence my choice for the (very much) shorter R1 motor

Rear engine with Turbo Hyabusa will give more grunt & grip than a front mounted "anything" :-)

The kits you can buy for front mounting a bike motor only allow the fitment of the early R1's. Apparently they are a bit smaller than the later model R1's (and MUCH smaller than the Hayabusa).

Having said that you could always fit it to a C.. C.. C.. C.. Clu.. Club. Nup, can't say it.

Yeah JC,,, but the R1 isn`t renowned for it`s gearbox strength or longetivity,,, hence one of the reasons i`ve made my hillclimb car as light as possible

A Turbo charged Hyabusa would be the choice of champions, "IF" you could get it to fit neatly into a """"Round-nose"""",,, you can fit just about anything into a Clu...,,, a clu,,, ah those square fronted things :-)

(Ahem),

There are those of us on here that love our clubbies!

Anyway, Matt, Kawasaki are now claiming the mantle of the most powerful production built M/C in the world - see here:
http://www.kawasaki.com.au/index.php?category=motorcycles&sub_category=4&product=49&product_details=specifications

=> 199hp at the sprocket!! :shock: (This is a massive 17hp and a whopping 16Nm more torque than the 2007 spec 'Busa, where's it going to end? :twisted: )
Oh, and for those of you who are hung up on this emissions BS, both bikes meet Euro 3 and Tier 2 regulations.

And these are the rear diff units I was thinking of using for our turbo 'Busa powered hillclimb and track car.

Hi Guys,

do any of you know of a manufacturer who does a gearbox or similar with reverse gear to use a motorcycle engine with a car (i.e. a mini)??

Cheers
