As my bike has now got a Cat N to its name I am also in the process of putting her back on the road for me to keep.
I wasn't riding the bike at the time someone else was and they reported it on their insurance and got paid out.
I rang my insurance company as its renewal date was coming up and they knew nothing of the crash and were unaware of its Cat N status.
They said I will have to get it MOTd to make sure it is roadworthy and then they will look at renewing my insurance.
Damage to bike was left headlight cracked, nose fairing cracked in several places and deep scrapes, broken front brake lever and ripped the standard exhaust can off the bike. Got to make a bracket to hold the clocks and other little things to tidy her up and she will be ready for her MOT.
I wouldn't like to buy a bike if its been in a crash I don't think anybody would but if it was cheap enough and you got the knowledge and experience to put things right again I don't see anything wrong in buying a Cat N for an everyday commute.
