In case this is useful to anyone in similar difficulties - and I didn't know best place to post so feel free to move if better elsewhere?

I like the flip front BMW System helmets, but not the price, so bought second hand...stop before you even start :blagblah...la la la... :augie I'm not listening! :P

Though I got the size I've had before and I'd tried on OK in shop I found I was getting pressure points on my forehead making it impossible to wear for any period of time. Agony. :mad:

I thought about all sorts of options but then suddenly thought - take the liner out and try it on, on its own. Yepp, bloody hell that's tight. It's not the helmet - it's the removable cleanable liner!

I trimmed the threads at both sides at the back were the liner is assembled as there is material folded over there and then joined them together 'unfolded', thereby gaining about maybe 10mm either side.

I stitched a white bit of thread were the original fold went just so I could see difference + if the liner ever 'sagged' I could re-assemble to original size.

I tried it out for a few rides and all was good so I formalised the stitching.

Seeing as I've now ridden about 4,000miles pain free I think I'd say it's been a success :thumb2

No long term issues I can see, helmet fits 'snug' and liner can still be removed so no loss of function or safety.

Just in case anyone finds themselves in a similar situation, better than binning hundreds of pounds or helmet or going even bigger - if it's just the liner you might actually end up worse off.

As for the legality of anything suggested above "on your head be it" :augie

Pic 1 - as is unmolested

Pic 2 - plucked stitching to unfold

Pic 3 - rejoined - red cross-stitching - with white thread were fold original was

Pictures have loaded in opposite order...in case anyone is too daft to realise :rolleyes:

I am not professional seamstress before you comment :D

Interesting - I was a 58/59 in my old System 6 helmet but had to go to a 60/61 in a System 7, with the result that it no longer fits in my top box (larger shell size). Not sure that I would have fancied butchering a brand new liner though. :beerjug:
