Hi people. I am sorry if I will have mistakes in writing because english isnt my mother language. In my country go karts arent popular . There arent any shop with go karts parts and go karts in my country so all stuff we are going to buy on ebay. My frends and I decide to make our go kart to drive it on closed runway. We are thinking to put on go kart engine from Gilera motor 125 ccm. Is it enought ? Also can we use brakes from gilera for our cart? I designed frame . Is it better to use circle tubs or square tubs? How much will cost as wheels (which size we should take ) and everything what we have to buy . Can you write what we have to buy for go kart except engine and frame . What do you think about this design of frame? Thank you

What is your mother tongue, what country are you from?

Gilera motor 125cc is a 4 stroke engine, yes? You can easily use the gilera brakes...

IMO, your frame is a bit overdone, you have a lot more material than needed, you only need 2 rails, not 4. Also, I don't like the way the axle runs through the frame, unless you have the rails reinforced & bearings fitted to them. The overall shape is nice though...

Round or square tube is mostly personal choice; some people think round looks better but, square is easier to work with, no "birdmouthing" (look it up) to deal with...

Thank you

Yes gillera motor is 4t.

A 4 stroke 125cc engine will work well

I was thinkg on safe when i was design it because its my first frame.

It's natural to go overboard with your first design, I was just giving you some advice

What you should sugest for axle !

Use the search button at the top of the page to see others axle mount setups...

You will find there are two main types; flange which need a plate welded to the frame rails & pillow block

I hope so it will.

Thanks for advice . I was thinking to put 8point roll bar . Will it be to havey ? What size of tubes i should use. I think that i will put flangw axle bearing.

I have merged your two threads into one. It is better to keep everything in the same thread unless you are discussing something totally off topic

 

[GoKartCro]

Ok thank you! Can you help me . Is it posible to use belt for bmotorbike or its better to use chain on kart ?

 

[mckutzy]

Hello and welcome,
Chain is better because there is the more verity of sprockets and clutch interchange, in case a ratio needs to be adjusted. Belts need a specific pulleys and belt to work properly, not to mention they need to fit the axle and shafts for them to work.

As Mckutzy mentioned, chain is better for a number of reasons

I was thinking to put 8point roll bar . Will it be to havey ? What size of tubes i should use.

We always suggest using larger thin wall material as opposed to smaller thickwall material.

There are no dimensions on your design, can I assume your kart will be around 6' (1.8M) long? if so, 1.25" - 1.5" (30-35mm) square tube with 0.65" (1.6mm) wall thickness will be good for the frame.

The rollcage will be more difficult because it looks better & is stronger if the tube is bent to shape rather than cut & welded so, round tube is better...

 

[GoKartCro]

Fabroman yes dimensions which i was thinking are 1.8 m and 0.8 m . I am working on new design so i will post it tumorow . Is here somebody who sales parts and he would send it to europe ?

 

[OzFab]

There are some that send parts to Australia from USA so, I don't see why not. Shipping costs will be rather high though...

 

[GoKartCro]

Yes I see. But if somebody who lives in EU shipping wont be high and there is no tax !
