Disc is mullered,(I could tell that),but caliper has also overheated to the extent that Steve is not confident that a rebuild would make it usable.
(It is now an attractive light gold colour due to the roasting....)
A new caliper is 800 bucks on the BMW-USA price list,so he's trying to find a good,"pre-enjoyed",item.
However,the cost of the repair is nothing compared to the torture of riding his CB500 loan bike the 32 miles home.
Seat so soft it feels like sitting on the frame rails....knee ache after 27 miles....no wind protection....gutless unless you wring it's nuts off...front brake feels like grabbing a handful of rice pudding and finding a stone in it....if I had to ride one of these as a learner it would put me off bikes forever.
It better be economical otherwise I really won't develop any feelings for it
....and I love anything with two wheels and an engine...my "collection",bears witness to that particular flaw in my character
