My opinion...use your own bike.

Cost aside, I'll bet you have a ridiculous excess on their bike.

You wont be used to it, so it'll take you that much longer to get to grips with it. You'll just constantly worry about binning it and the associated costs.

At least with your bike you will be used to it, more familiar with the limits, and can get on with enjoying your day much sooner.

Just my 2p.
