Crack in rear disk

Hi guys, ive just been out in the sunshine scrutinizing my bike (2001 R6) as I do most day and have come across a crack in my rear disk. The disk is in pretty bad condition and ive had a replacement saved in my ebay watch list for a few weeks now just had other things to spend my money on. KTM forks seals decided to piss out etc..

https://www.ebay.co.uk/itm/220993970832?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_1916wt_1189

So now ive had to bite the bullet and order it along with a new set of pads. I use my bike every day to get to work and also for hooning around the lanes etc Mr. Green

So the question is would you lot trust it for a few days maybe a week untill the new parts arrive and i can get them fitted saying that ive proberly been riding like it for weeks?? Also what do you think of the replacement disk ive got lined up?

Heres the disk Sad

Depends how often you use your rear brake, I never use mine so that wouldn't bother me too much, saying that.. I'd probably never notice Very Happy

Bloody hell bet his arse went like the clappers when that happened!

Round town and at slow speed I do use my rear brake a fair bit so will have to keep reminding myself not to use it till its sorted.

I've ridden on worse fronts. That's not much to go by though.

Just use the rear less.

For the sake of £88 i'd just replace it - whether you use it or not - sort of thing that would bite you on the arse.

Definatly getting replaced mate, am ordering the new disk and pads on Thursday when I get paid.

Gave it another look over this morning and found another crack in it a couple of inches further round. It's smaller than the one pictured but is worrying!

I've ridden with a cracked rear (multiple cracks now) for a couple months now without issue. I should replace it (got the spare disc, just no time) but it hasn't impaired my riding much and has held up alright. A front I'd get sorted immediately however.

TLDR: It'll hold up fine

Another option could be to drill a small hole at the end of the inboard crack to stop it propagating further. At least you would know it couldn't get worse. Plus it's one more hole for cooling. Very Happy

Well I fitted a new Brembo Serie Oro disc today along with new pads so I'm all sorted.

Don't think I'd bother drilling a disc when a new disk only cost £88 not worth it imo.

Thanks for the advise Very Happy
