Rear mudguard mounting varies from donor to donor, but the key issues are covered with the bandit example below.

Things to keep in mind -

1) The guard should extend below a line drawn at 45 degrees in an aft direction from the rear axle.

2) In most states the expectation re indicators is that there are 2, and they be at least 280mm apart and be within 300mm of the rear most point of the vehicle. Hence need to be mounted on the side of the guard behind a vertical line drawn through the axle line

3) Your might want to fit some kind of struts to support the guard much as per the pics. ie. They can attach under the indicators.

4) Don't forget when positioning it to make allowance for the movement of the wheel forward and aft over time for chain adjustment.

5) On the Bandit we use M8 rivnuts on the top section of the swingarm that the bracket is attached to, but some bikes have plenty of meat in that area and it maybe more appropriate to drill and tap a M8 thread.

Have fun, Andrew.

Evening Andrew,
Can the rear mudguard finish at the line of the indicators (making the wheel easy to get on and off) or is it a engineer requirement to extend to the rear?

Hi does that retaining strap off the brake to guard work as the chain stretches? I would think it would twist and pull down the guard a little.

Hi Shane,

Yes its required by some ADR or another.

I should make a general mention at this point that some of the things you may see on Hot Rods don't apply at all to ICV builds. One of the lenient things they have is minimal mudguard radius.

How is it going up there BTW. Making a bit of progress?

Regards, Andrew.

Hi Terry,

That strap would of course be further back if the indicators were in the correct spot and in turn on a flatter part of the mudguard radius and I suspect would not lower the guard much when sliding the axle forward and aft but yes you have a bit of a point.

Mudguard mount reinforcement is really open to the builder....

I would rubber mount a strut in a more aft position than in the photo.

The one in the pic is very firmly mounted and isn't going anywhere but I suspect there maybe a fatigue issue, as the guard is unsprung and will cop a hiding when driving on rough roads.

Oh and I should have mentioned in my response to Shane that you can get the wheel in and out just fine with the 45 degree extension of the aft end of the guard present, well at least on the Firestorm and Bandit.

Regards, Andrew.
