I did the same thing. I took my test in September last year, at Hendon (thanks to CamRiders), got home and took my L plates off then went on the 25, managed to overtake a lorry (going up hill)!
Also a vertically challenged rider. Managed to get my leg over the Suzi GS500 for testing. Now got a Honda CBF600 (it has a low seat setting).
I’d really like a SV650 because apparantly they still run/ride really well after they are restricted. Plus its suppose to be a good beginners bike… :)The money I (we) had saved was suddenly pinched from under my nose on Sunday night when my husband found a track bike… being the nice / understanding wife that I am, I said he could use the money for that and I’d start saving again for mine!!! Its not like I’m with out a bike, I’ve got my cbr125 and I can still practice / master all the things I’ve learnt on that… bit dissapointed but never mind! Hubby’s over the moon, so its all good!!
It is definitely an advantage when they are in a car - they can’t get so close to pick you up on minor positioning and white line issues, and are easily lost - lost instructor is time gained!
