Can some kind soul give me the dimensions for the front wheel spacer on the axle of an LM1.

Just the length ie fork inside to wheel, would do

Obv it's narrower than the LM2 one with wider yokes

I've got my friends Le Mans dismantled in the garage at the moment. I'll measure the spacer tomorrow and get back to you.

I think they are the same size...the difference between the LM and LMII is the latter have spacers between the wheel hub and discs for the extra width. Stein-dinse lists the same part for LM1 to III for the axle spacer - https://www.stein-dinse.biz/eliste/index.php.

When I fitted an upgraded racing LM front end (forks and headstock) to my LMII, I simply moved the disc to wheel hub spacers to outside of the discs and the LMII axle and spacer fitted perfectly.

Sorry I forgot to get back to you yesterday. The spacer on the LM1 I'm working on is 34mm long. Hope this helps.

Funnily enough, Ive just had a message from Roy at O&S re his stainless spacers, and he says:

Mk1 LM=25mm
Mk2 LM=32.5mm

so...

mk1 has 180mm triple Clamps, MK2 has 195mm triple Clamps.

The extra 15mm is taken up by the spacer on one side (7.5mm wider) and the Axel itself that has a wider end and acts as a spacer (one of your fork legs will have a larger hole for the Axel for the wider end that acts as a spacer) t

The other item that needs addressing is the brake disk spacing, which is done by a 7.5mm spacers inboard of the disk on each side
