braking and stoppie questions

[stranger12]

Hello,

I normally do stoppie on my bike but occasionally can feel front locking up and suddenly slide. I can't seem to work out what is causing that apart from knowing this only happens on low speed so maybe i am doing my stoppie to late.

Also when slowing down and hard on front brake would you shift down ? i think I shouldn't as that would make the traction even worse so think i have to shift down only after I think by shifting down I am not going to engage engine braking . I hope this makes sense

I appreciate your comments.

many thanks

That will be karma telling you to stop pratting about and ride properly before it kicks you up the ass.

How is engine braking going to affect the front wheel?

"I normally do stoppie on my bike " I would suggest that the OP should be riding in a controlled way with both wheels on the floor in his "normal" braking. Stoppies are for deserted car parks.

not on road rather before traffic light or in a contained safe area

G, my bikes do have terrifyingly awful brakes but I did destroy my hip when I crashed after locking the front end up.

Just by a speed bump mate, oil from bashed sumps, rubber from heavy breaking and poor obs by me. Hitting the bump fractured my hip, ribs and hand, my helmet saved my good looks.

You're the plonker that thought your SV was a supersports aren't you?

January is not the time to 'normally' do a stoppie on your way to work.

IMO if you keep doing these, you're going to go over the bars at one point. I'm sure with this, you're going to have to do it lots and lots and get a good feel for it, have great balance etc etc.

Like riding a bicycle, you'll learn by falling off a couple of times, or at least I would expect that

I've never stoppied, so take this as you like but I would suggest it locks if you are not being progressive enough, either that or the surface isn't good enough.

im guessing that its the road surface

but still dont see why you want to do this as surely it causes extra wear and tear to the suspension of the bike

Go practice them in a car park/industrial unit when its closed.

Practicing them on the road would be silly

As in... do a bigger stoppy? no I am not doing a rolling stoppie rather just when i am comming to full stop

What tyres and bike? Tyre at front is Avon and rear is Dunlop Roadsmart which are sport/street tyres

Avon front? In b4 "dey are shit"

I thought stoppies were easier when moving. Only tiny ones mind

[G]

I have NEVER found avons to be good tyres for grip.
I have experienced just this sort of thing with them - they can't handle 'emergency' situations very well.

So remove my advice to do a bigger stoppy.
Yes, a rolling stoppy with the front applied progressively may be more likely to grip. But the Avon in my experience is more likely to let go.

A lot of london tarmac is pretty broken up, especially coming up to junctions - do be aware of the conditions. Look for good shell grip.

And a decent front tyre.

Don't do in damp conditions unless you are very confident in your tyres.

You've still failed to mention your bike; I'm going to presume an SV650.

apologies it is sv650 and my rear is roadsmart II dunlop, is dunlop any good ?

I think my Avon is storm ultra 2 . the rear kept getting punctured so had to swap it

what would you put in there that is good for road and track days? I did some research and there was Michelin pilor road 3, dunloap road smart and continental attack I think it was and decided on dunlop.

Michelin was expensive so went with dunlop

What do you guys suggest that is a very good rubber?
