Building a Bucket.

**speights_bud** · 12th July 2005, 17:17

Took part in the bucket races in Waipawa this weekend just gone. The A100 performed quite well for me and even for a 2-smoke was very reliable.

I'm interested in building a new bucket bike with something along the lines of a 140cc 4-stroke engine and a rolling frame including disc brakes and callipers. I'm thinking that disc brakes will work a hell of a lot better than the drum ones on the A100 atm

.
Any suggestions and/or offers would be much appreciated

FXR150. Capacity limit for 4-strokes is now 150cc.

Damn.

Feel ripped off

since I paid more than 74c for my lovely

metallic green bucket.

And all this time I thought it was a motorcycle and a bucket was where I put my warm soapy water in for cleaning my motorcycle

I took part too on the RD50 and it was cool but I want something with more power. The same Idea as speights but like a CB125 engine in any old frame I can beg/steal/be given/swap and put some fat arse tyres on it. Dad's old GSXR tyres would be suitable. If they fit. And I would need rims of the same size.

I'm no expert, but I reckon putting fat tyres on would be a baaaaad idea. They will slow down the steering and make the bike handle worse. A bucket doesn't have the power or weight to need fat tyres. Take a look at the 125GP bikes, they have skinny wee tyres and corner faster than the MotoGP bikes

But you can lean it over a lot more and it gives you more traction

Have you seen how far they lean 125GP bikes over? They get waaaaaaay over. I'm sure someone like F5 or speedpro will turn up to offer their opinions on this.

I not very confident at riding. I would feel uncomfortable leaning skinnies over real far.

No , you can (other things being equal) lean a skinny tyre over further and faster than a fat one, because there is less shoulder transition . A skinny tyre can come closer to the perfect semicircle section (to envisage, imagine trying to lean over using a wide "car" tyre off an SUV - impossible). "Fat" tyres (wide ones really) have to have squarer sections.

More traction is only an issue if the smaller tyre can't cope.

I've ridden 2-wheeled bikes with fat (balloon as found on quads) and standard tyres.

They have less cornering ability than those with thin tyres, but have much less wheel spin in swampy ground, mud and river sand dunes - still can get stuck

Oh, and they can aqua plane with only 2cm deep water in Mr Farmers paddock

I'm meaning like my dads old GSXR tyres. Not quad tyres.

True. Didn't think GSXR's came with quad tyres.

I might have an old 'bucket' with some TLC, what kind of speeds should these be capable of?
40,
50,
60,
70,
80,
90,
the ton?

Tracks tend to be smallish so it's more a matter of acceleration rather than top speed. In saying, I read somewhere that fastest buckets get up to around 80/90kph on the track.

Nah we would have easily been hitting 120kph on sunday, the best one could do 130 i reckon.
