Having completed (mostly) the transplant of teh GP100 (disk brake - woo!) front end to the A100 Im shocked by the flex in the forks..

..only the bottom yoke has pinch bolts and I have not yet got a mudguard fitted. I'm assuming that the degree of 'twist' is normal and will be fixed by bracing with a mudguard - otherwise it would be unrideable I reckon.

Those steel mudguards or the steel inserts in plastic ones do a lot of bracing.

I presume the top yoke is a taper fit so it won't cinch down until the top-caps are tightened down fully

My experience of GP100/GP125's is that the forks are quite solid, it's the swingarm bearing being made of cheese thats the comedy part. It's like your riding a seesaw when you hit a bump half way round a corner.

Good point.. maybe i did teh lower yoke up first before teh top was 'snug'. I'll go and check..

Ha, the A100 seems quite solid at the back.. Still like moped but in the main beefier I think.

My installaton has left out the original headlight brackets and associated rubber grommets/seals..that cushion teh bracket form the yokes.
Hard to see how these could help avoid teh twisting though..

... I may fabricate soem kind of brace and order a mudguard.

This is the issue - seems these are needed to clamp the top yoke securely.. Sad
