Recommendation on budget chassis for bike engined build
Opirun - 31/3/13 at 09:20 PM

Hi all,

I am looking at options for a bike engined kit (first build). Does anyone have any recommendations of chassis for my build. I have been looking at Tiger, MK and GBS Zero, however, in my other post in the BEC section someone suggested MNR. Looking forward to learning from your experiences and suggestions. Thanks.

At the moment I am looking at cheaper carbed engine options, perhaps R1 or Fireblade.

Thanks.

If you are on a budget the GBS zero looks like its worth a look. whilst MNR make a good chassis it is hardly a budget option

That kind of makes the decision for me then

I don't know how well I could integrate a bike engine with the GBS zero option?

Best thing is to ask them - they might be able to supply what you need.

I replied on your other thread. Consider Aries Locoblade (http://www.ariesmotorsport.co.uk), for a budget but good chassis that is planed for a BEC installation.
And Steve's support is marvellous.
And Aries is just 30 miles away from you.

+1 for Aries, AKA Stuart Taylor (well, ex ST anyway).

Pretty much all of them are good
When you fit the bike engine with
cradle it stiffens the front end considerably .

i dont think there will be much difference in price between most of them, westfield and caterham not included!
budgets get blown on fancy bits, digi dashes,ecus,carbon fibre,alloy etc. if you keep it basic for now you will build any of them on a budget. then once your confident in the car, upgrade bits as you see fit! good luck,
another thing to consider is resale value. some hold there value far better than others so one thing to consider is that if they all cost similar amount to build then look at current second hand values of each model! this way you can get an idea of what its worth once complete

for a budget build buy part built.

Its a bit of extra hassel unpicking someone elses work first, but you save a considerable amount. Just make sure you buy a decent brand, as some home made locost part builts are badly made/welded.


Opirun - 1/4/13 at 01:01 PM

Thanks everyone, lots to think about. I figured that something like a well built mk would sell for a better price that a , this is not to say that they are a better kit, just shear branding.

Part build is a nice idea, but as you say quite subjective to each kit. Are engine mounts typically ready for a bike engine or is custom modification required?

daniel mason - 1/4/13 at 01:18 PM

you would need custom mounts unless buying a new chassis. i know MNR cater for all bike engines and make cradles to suit. and they fit! which is more than can be said for some!


Opirun - 1/4/13 at 03:42 PM

Ah ok, I see, such as this (as an example) http://www.mksportscars.com/parts-engine-mounts.html

I am quite surprised and impressed that this is all this is required for mounting the bike engine into the chassis, or am I missing something?


renetom - 1/4/13 at 04:31 PM

That looks like the cradle we purchased from MK
for our R1 engine
There is also a crossbrace & 2 lower mountings
Which have to be welded into the chassis which
are not shown, but easy enough to fit.
and they come with the kit.

As for the chassis, I would buy a chassis made by a kit car manufacturer , not from
some guy who's welded it up in a shed somewhere, you may want to drive it hard
and its your life on the line .
Many years ago I was an inspector at an engineering company in Dorking who make road sweepers , one guy who was welding engine mountings was an artist
his welds were the most beautiful Ive ever seen, but bash them with a hammer & they fell to bits.
This is not intended to disrespect those guys who have made their own chassis.
Some are probably better than manufacturers ones, but if you don't know
The guys qualifications , beware.
Just a personal opinion .

Thanks renetom.


Opirun - 1/4/13 at 04:58 PM

Just wondering why I don't often see the CBR1000 engine being used in a kit car? Anyone know why?


Tazzzzman1 - 1/4/13 at 05:08 PM

Check out Roadrunner racing also. Reckon a Bike engine would drop in an SR2 pretty easy, as the kit is light weight to begin with. If not they are developing the LM1 bike engned car. Now would be a good time to talk with them and negotiate a bargain...

Presume you meant the old '92 ish
Theyre old and heavy, other than that no reason why not, they're good engines, my mate has one in his


Opirun - 1/4/13 at 05:26 PM

Sorry, I meant something like this

Honda CBR1000RR CBR 1000 RR Fireblade 04 ''RR4'' Engine Assembly-read description | eBay


ReMan - 1/4/13 at 05:35 PM

Nothing wrong with them, in fact they race with them
But theyre not budget.
That's nothing except bare engine, so another few £00 to get it running


Opirun - 1/4/13 at 06:16 PM

Thanks ReMan,

Not sure what would be a good example of something ready to drop into a kit? Just so I know and learn what I should be searching and looking out for.

Opirun - 1/4/13 at 08:02 PM

Thanks 40inches, I will take a look.

Seeing as I am in the chassis section. I wonder how these kits compare in terms of handling and if any of them suffer from any obvious design issues? Would be interesting to find out more about the chassis in terms of there engineering and performance.


daniel mason - 1/4/13 at 08:28 PM

the problem is you want budget chassis but good handling etc! its all relative but to get some of the above to handle like a well sorted striker/fury or westy will cost quite a bit of money.
building a new car will definately cost you far more than buying part built or built as many on here will testify!
theres a cracking little bec striker for sale on pistonheads in spaceframe section with a brian james trailer and he will let it go for under £5k all in as i have spoken to him about it a few weeks ago. a bit of tlc and it would be a very quick car and give you scope to upgrade when you get used to it!

Opirun - 1/4/13 at 08:34 PM

Your absolutely right Daniel, can't have it all. Of course budget will lead to performance and quality compromises. I am going to take a look now on part builds and see what I find. Thanks.

ADDED: in fact please ignore my question about handling, etc. It was silly question based on the fact that budget is important.

The Aries chassis is by far and away the best value for money chassis if you're looking for something that will perform well and are willing to sacrifice a bit of 'ease of assembly'.

All the fundamentals are there (stiff chassis, good suspension geometry etc), but with none of the gimmicks.
