Frame-Dimension für das Begradigen / Frame dimension for straightening

Hello I have just picked up my 103-a1 and have stripped it down for restoration.
Can anyone tell me the correct measurement from the edge of the vale cover to the edge of the handle bar bearing please see pic’s. (572mm)?

Hallo ich habe gerade mein 103-a1 abgeholt und haben abgespeckte es für die Wiederherstellung. Jemand kann mir erklären, die korrekte Erfassung von der Kante der Vale-Abdeckung an den Rand des der Lenker, tragen Sie bitte siehe Pic's

The other measurement I took was form below the front engine bracket to the same point (633mm)
Die anderen Messung habe ich war Form unter der Frontmotor-Halterung zum gleichen Zeitpunkt

Orif so some could let me know the correct angel for the head stock that would be great

Sorry for my poor German (MS translator)

regards and thanks Iain

Hi rolandwi
i think it is no good idea doing the measurement as you did. I t is not very exact because the engine is fixed in rubber mounting brackets to keep the vibrations away from the frame. A better way of measuring is from the edge of the handle bar bearing to the 12mm thread of the frame where the spare tyre and the rear covering are fixed.You can also check the measurement between the handle bar bearing edge and the two 6mm holes where the tank is fixed with. I have got an A1 frame on the attic of my house. I am going to check your measurements when you tell me them and let you know if they are the same at my A1 frame.

From handel bar stem to fuel tank fixing holes = 900mm

And

from the handel bar stem to the spare wheel mounting bracket = 1100mm

Any help is much appreciated

Hi
i think you have got a problem. The distances at my frame are: 114 mm at the rear monting plate and 94mm at the tank.
Seems the frame is bent at the front tube, but it is possible to straighten that with an hydraulic jack. I have done that before

Hallo Rolandwi,

wenn Du noch Tipps zu Deinem Rahmen brauchst, schau doch unter FAHRWERK/KAROSSERIE nach.
