Reclaiming VAT on mileage for private motorbike

[StevensOnln1]

I was easily able to find that the approved mileage rate for motorbikes is 24p per mile, but can't find anywhere that says how much VAT can be claimed. Motorbikes aren't covered on HMRC's advisory fuel rates page and I haven't found the answer by searching.

Does anyone on here happen to know?

I can't find anything either. Neither the AA nor the RAC seem to provide figures (HMRC use them for their advisory rates).
I would use the advisory rates as the starting point, say 15ppm (petrol cars up to 1400cc); perhaps multiply by: motorcycle rate/car rate; ie: 24p/45p.
This gives 8ppm - is this a reasonable cost of fuel for a motor cycle?

This website purports to give average mpg for different motorcycle models. Perhaps you can substitute the mpg in the formulae at the bottom of HMRC advisory fuel rate page. :|
