    Of course. But she can handle a bike. She's happy on my Mad Beta and not scared to fall off. 4 times in 2 hours

    It was being scared of having the urine extracted that stopped me from falling off

    It's deep sand and soft stuff where I take her.

    My explanation for clients:
    Ease and squeeze, not grab! Front is the main stopping brake - that's why big bikes have two large front discs and only 1 small rear.
    As the front is applied and the bike slows, the weight moves forward and squashes the front tyre on the tarmac, so you can brake haaarrrrdddeeerrr, just not HARD!! (as in grab).
    Since the front is getting heavier, the rear is getting lighter. The better you get at the front, the less you can do with the rear.
    I don't go on about percentages as I don't have a pressure guage on my hand! The 75/25 thing is just a rough concept to help explain, but it's a variable depending on how good your front braking is. When you get your back wheel in the air, you're doing 100/0!!
    ABS is ace!! We've not had anyone fail their Mod 1 on e-stops since getting bikes with ABS. Before it was doing a 20' smoking skid with the rear that was a serious, if nothing done to correct it, which was often cos the folk weren't aware of it.
    On the Mod 1 test it doesn't have to be the best stop in the world! Don't have to do a stoppie! Just reasonably proficient. Not a fault or a fail if the ABS kicks in.
    If you seriously grabbed the front brake and looked like on the edge of losing control and only saved by ABS, it could be a fail.
    Go with A - Bbbbbbbbbb - C as the method. A for accelerator, B for brake, ease and squeeze, clutch towards the end.
    Not a fail to stall as late with the clutch.
    Even the DVSA have got a lot more reasonable about stuff - used to get minor faults for getting the clutch in too early. Haven't had one for 3 years! There's only so much friction on the rear wheel as it gets lighter, so if you're getting lots of engine braking, you can only do less rear brake. It is a good plan not to pull the clutch in really early from high speed on a m-way. From 32mph on Mod 1, what? a whole second earlier? Doesn't make hardly any difference to the stopping distance.
    Practice is good and what most bikers should do more of. Grabbing is bad, especially if no ABS! We grab it when we're surprised and our survival instincts kick in. ABS can save us from ourselves.

    Hopp rider training had the 'handshake' example, you might give a firm handshake - but you don't initiate that by grabbing! Hold, then squeeze.

    And the other thing overlooked by many trying to explain by using the percentages is that 50:50 in the wet is really 25:25 - ie reduced braking effort. But in my collection of 'Really?' info, to challenge sacred cows etc., was a photo from Bike magazine, of their test rider stoppying a bike, almost vertical, headlamp reflecting off the wet tarmac

    My two-pence-worth is that as soon as I acquired a new bike, I'd ride it out and on the first few rides always tested that front brake. I reasoned it was a lot easier to get to know the feel when not in a "panic-stop" situation. You can prepare to let go, prepare to get a foot down at the last second and so on. It paid off. On my first ride out on my first [and heavy!] Triumph I was in a line of traffic when a builder's lorry about 200 metres ahead ploughed straight into the back of another lorry parked at the side of the road causing everyone there to test their emergency stopping behind the lorry. Fortunately I was ready and my 220kg Sprint was never in danger of toppling. After that I regularly repeated the procedure at leisure from various speeds , always on a quiet road, in a straight line of course and taught myself a lot. I would recommend practising at leisure.
    HTH?

    My twopenneth is that it might be that learners vary in their tendency toward either over- or under-doing the braking. My son, for example, last year came out of CBT having not really learnt how to brake sufficiently. We practised together and I got him to apply more force to his braking. Maybe other trainees are the opposite - you need to teach them how not to skid (although as Lake said, ABS if fitted tends to take care of that these days).

    Clearly it wasn't in the '70s on a Honda.

    Like Hawker, I make a point of regularly practising hard stops as it's so easy to get (a) complacent and (b) out of the way of doing it.

    I have yet to test this with the Guzzi's linked brakes however......
