I'm not sure if the OP has sorted his issue but:
1) It's not likely the driver will be prosecuted. The OP was correct in informing the Police, but it's easier to leave that in their hands.
Prosecution would not serve as any real benefit to the claimant, other than satisfaction that the driver is punished on a criminal level.
2) If the OP is injured, and would like to make a claim, he should save his time doing all the investigations via the DVLA and sending letters to the driver, and instead get a solicitor to act on a "no-win-no-fee" basis, and simply submit a case to the Motor Insurer's Bureau (as the case is technically an "untraced" driver claim until the name of the driver is known).
The MIB will do all of the investigating, and once they find the driver (which I think is highly likely in the OP's case) then they will confirm details of the driver's insurance to which the OP can make a claim against the driver/his insurer.
Worst case scenario, the TP denies involvement and/or is uninsured. However, in either of these events the MIB will still make an award for compensation.
Caveat here is:
If MIB deal with it as an "untraced driver" claim - the claimant will not be able to claim for damage to his bike or property, instead he should claim the excess he paid for the claim he made to his insurer for these losses.
If the MIB find the driver, but he is not insured, he OP will still be able to claim for both his injury and bike (and the MIB will sue the driver directly for the money they pay out)
Hope this helps (y)
