If you can stretch to W london, SRS Motorcycles in Hammersmith (Trussley Road) are frankly excellent in every way.
Contact SRS on: 0208 7412114
Its about 2 min walk from Hammersmith Tube, so getting back to work/home for the day is sorted.

Not sure if this helps as I don’t know there full address, but on the Harrow Road behind the Suzuki Spares Shop, and the one I use is also on the Harrow Road 7mins from the Suzuki Shop in the central London direction.
If any of these are local to you im sure I can dig up there addys
Hope that was some kind of help, the Artist 
^ Is that the motorcycle service centre? I think I’ve passed it a few times.
Old looking shop, but they are a good bunch.
I’ve always got mine MOTd at Chasbikes- great suffolk st, SE1. Grumpy bunch but completely competent.
