PE wheel offset

[Maicoman]

Just wondering if someone knows or can measure the rear wheel offset for a PE400/250. I seem to have misplaced my notes taken during disassembling the wheel.
Cheers Brooksie.

I can get it for you should have one or two around the shed somewhere.

You could simply true it in the swingarm to get the offset correct. Thats what I did for a 82 PE250 I built.

Thanks Hardo I was thinking of doing that. From memory the cush drive side of the hub was about 20mm offset from the rim but I would like to check.

If you could check Frosty that would be much appreciated.

Heres a couple of pics from a while back.

Yes I will do it sometime this week for you I am sure I have some 400 wheels about worst case I can pull one off I have a few on complete bikes so no drama either way.

I came up with a wheel offset idea a while back I posted on here but know one replied
looking at my bike one day ,I thought I would see how close the front and rear wheel offsets lined up in a straight line.
so I got my alloy straight edge 50mm #25mm and sat it on blocks next to the wheels.
I then checked to make sure the front wheel is true and in the centre of the forks .
then I made sure the rear sprocket was dead straight with the front sprocket using a custom straight edge I made up or you can do it my eye.
I then measured from my straight edge to the centre of the front rim and the rear of the front rim ( so the straight edge is running in a straight line with the front wheel.
Then I measured to the centre of the rear rim at the front of it ,then I measured the rear rim at the back of the centre of the rim.
The point of this was to see if the centre of the front rim lines up with the centre of the rear . cornering was my factor here.
my bike was 2mm out from front to rear .
 I wasn't going to lose sleep over that not bad for a old dirt bike , may be different for a GP bike...
so my point is a PE400 may have a 20mm offset that may suit your bike but not yours mates PE400 , so every PE400 frame and swing arm may have a small margin in being straight .
As HARDO said true it in the swing arm on the bike and centre the rear rim with the front rim...
Hope this makes scence just my views on wheels and offsets

Here's one bro... I have a few on bikepics...

Oh and Mick... you put a lot of thought into that mate!  Good idea tho !!!

Thanks Mick for your in depth explaination, very useful. With the PE because the rear sprocket and drive hub are a unit it is pretty much always fixed to the swingarm, hence the quick release so it should pretty much run true with the front sprocket. I understand not every bike is the same and will vary between each one but a ball park measurement as I reassemble the wheel it all I need. I will true it up in the swingarm as Hardo mentioned.

Nice pic Hardo. Do you still have that bike?

Looks good Dave, have you still got it?

I got 21mm on sprocket side measured on outer edge of rim.

And it was just about the same 20mm on the free side.

Nah I restored it for a mate. He is local near me and has it in his hallway at his house.

So.... I know where it is if anyone wants it.... 

It goes SO well - I tell you it actually surprised me big time just how punchy it was !

.......for a suzuki ....
