The Aprilia Rs 125 Blog Contents



There are 5 bolts on the shock linkage - i used stainless steel allen cap bolts,nyloc nuts and washers.All of which can be purchased very cheap ,

M12 X 85
M10 X 125 (need to purchase m10 x 130 and shorten the thread)
M10 X 80
M10 X 75
M8 X 50

1 X M12 NYLOC NUT
3 X M10 NYLOC NUT
1 X M8 NYLOC NUT

2 X M12 WASHER
6 X M10 WASHER
2 X M8 WASHER

Next is the sleeves/spacers that the bolts pass through.There are 4 of these which cost a fortune from Aprilia.You can get these machined from mild steel then case hardened.Spacer sizes AFTER case hardening are as follows.

LENGTH O.D I.D

24MM 18MM 8MM
74MM 18MM 10MM
49.85MM 18MM 10MM
49.85MM 18MM 12MM

Next are the oil seals.There are 6 seals in total and there all the same size.

24mm O.D x 18mm I.D x 3mm Width 



Last of all the bearings.There are 3 bearings in the standard rocker.

1 off hk1812 - 24mm O.D X 18mm I.D x 12mm Width
2 off hk1816 - 24mm O.D x 18mm I.D X 16mm Width ( plus another 2 to convert to a 5 bearing rocker )

There is room to make this a 5 bearing rocker which will make it more stable buy fitting another 2 hk1816 along side the standard bearings.It's totally upto the individual wether to do this.
