rear axle length

[Purcell]

Ok I know I know. This I'm sure has been brought up a million times but can find an exact answer. What is the exact length of a rear axle. I know I need a 20mm to work with my rear wheel. But I need an overall length of about 12" (see pics) will stock rear axle get me there? I'm building my bobber from nothing. I didn't have a complete bike when I started this build so I don't have a stock axle to see if one will fit. Thanks in advance.

Just measured mine (while installed), it's looks to be about 10.75 inches.

Btw, do you still want that top tree?

 

[Purcell]

I need to wait on the top tree for at least a few days.

 

[Purcell]

So any idea where I could get a longer rear axle?

 

[figure8]

I'm not, there was somebody making them in the shops section awhile back. Not sure if he still is but maybe could make you a longer one.

Keep in mind you'll need to have bigger wheel spacers made to.

 

[Purcell]

Ya. Just haven't got that far. What do people usually make those out of?

 

[figure8]

Steel, SS would be best. Are you on Instagram by chance? I have someone in mind that might be able to help you out but only know him through there.

 

[Purcell]

No I am not. I suppose I could make one

The old KZ750 twin had a longer 20mm axle. I might be able to check length later.

 

[Purcell]

gggGray, that would be great.

GS750 and 1000 chain drive axle



KZ750 twin axle prolly same as 4 cyl 750 and KZ1000 chain drive bikes.

My phone will not allow me to zoom on the pics. How many inches are the axles?

 

[gggGary]

They are both about 11 3/4" from the head's flange to start of threads, the threads are longer on the Kaw.

Did you ever get this figured out?

 

[Purcell]

Yep. Bought a rear axle from a yamaha venture 1200. Worked perfect. 20mm and 12" length just as I needed.
