This is something I see asked about a lot. You can mess with the formula as much as you like to suit your circumstances, but I just wrote this one for another forum member.
No guarantees it will work, but beats being raped by a solicitor for a very, very simple thing.
The 90% reference is up to you, I just find it's a good way to get it over and done with.... keep in mind you are quoting new prices your your jeans, etc when they were old and worn, you'll get a new helmet, new jacket, can quote a dealer price for your bike, etc... so 90% is still likely to be as much as you really lost, if not more.

Dear Sir/Madam
I refer to the Smith Street, Blacktown traffic incident on 1 January 2007 involving your Kenworth truck REG-123 and my Kawasaki BIG-69 motorcycle.
Due to the circumstances of the incident, and confirmed by the recent Queensland Police investigation, I hold your driver entirely responsible for the incident and resultant damages. Please find following a schedule of damages totalling $9,999.99.
attach second page, with value for your bike and list of items damaged - jeans, shoes, backpack, jacket, gloves, helmet, etc, also any other clearly related costs like a rental car for the first two weeks, etc.
As a gesture of goodwill and in the interests of prompt resolution I am prepared to settle for $8,888.88 being a sum equal to 90% of my losses, if agreed within 14 days of this notice.
Please note that after this time the matter will be referred to my solicitor, seeking full damages in addition to legal costs incurred.
Thank you for your assistance in resolving what is a straightforward matter.
Kind Regards
