Title: shocks
Post by: Happy Eeyore on June 25, 2026, 08:05:57 PM

Does anyone know the length of standard rear shocks center line to center line of top and bottom mounting bolts?  What is the longest people have done?  Any in excess of 325mm?

Standard shock for type 248 R45/R65 is 325mm 

Other contemporary type 247 Airheads e.g. /7 are 340mm

Thanks Barry.   Do you think a 340 would work or would that make the drive shaft in more of a rotational bind.  My uninformed opinion is that a 340 should work just fine but I am often wrong, particularly about stock market movements.
