Engine braking - rear wheel lock ups

[DeanoN]

Is it me :oops: or did anyone else find when they first started riding V-twins that they kept locking up the back wheel due to the engine braking?

If I've been riding reasonably quick (I'm no knee down race expert) I find when breaking quite heavily and down shifting the back end locks up. I'm not talking major skids down the road but more the rear wheel momentarily locking up enough to make the back end of the bike twitch about.

I figure I'm down changing to soon after riding an in line four for the last few years, just wondered if anyone else had similar experiences.

[maddogsmithuk]

Give the throttle a quick flick when changing to stop the lock up's when going for change down at speed.

[slider]

yea m8 lots of torque ,quick blip on the throttle helps.
i some times do it on purpose pretending to be a walker or rossi :D

[WelshWop]

Yes blipping the throttle helps if your comfortable doing it. Yes you prob are shifting down too early. Just need to adapt to the v-twin. Also let out the clutch smoothly.

[Red ones]

Brakes first, then choose the correct gear for the speed!

[Peter Henry]

Yeah you can get away without blipping if your letting out of the clutch is smoooooth! You cant just let it fly out of your hand on a Vee twin mate,it can be similar to someone throwing an anvil off the back of the bike! :shock: :lol:

[Supervox]

. . . it can be similar to someone throwing an anvil off the back of the bike! :shock: :lol:

Surely, having an anvil on the back of the bike in first place would actually help traction - more weight over the rear wheel?

Therefore, why would you want to throw it off ??

Also, do you know if anvils are bike specific ? Or is is just a generic anvil that is required ??

:D :D :D

[jenni]

I do this all the time at the mo - only been riding the sv 2 weeks. Noticed it most in the wet. As the guys say I have found easier on the clutch stops it. Haven't got the hang of blipping yet.

Be careful in the wet, I went down two gears as some bird in a cage pulled out without checking, no indicators :evil: and the back seriously wobbled. slight brown trouser moment :oops:

[kwak zzr]

classic v twin! great in it :D

[NitroNorry]

I used to do this a lot when I first started riding the SV. It happens a lot less now, I think you just get used to the bike. Kinda like it now anyway :lol:

blip blip blip
and then i get that awesome backfiring/induction noise :) with my scorpion can

[Jamesv650]

just bang it down and let her slip.... what you worrying about ? its not going to make u fall off!!! just dont go down the gear box as hard if you dont want it to slide

[BURNER]

I find if you've got a standard pipe fitted you have more engine braking, fit a less restrictive pipe, blip that throttle and enjoy.

Not exactly the world's greatest advice eh?

I've got a slipper clutch 8) :wink:

You can either learn to blip the throttle on downshifts or be a little bit smoother with letting the clutch out.

Learning to blip the throttle on downshifts is a good skill to learn on it's own. It can come in if you need to loose a bit of speed on a dodgy surface where using the brakes might be just that little bit risky.

Thanks all for your comments, it would seem that I need to master the throttle blip - gentle clutch thing :)

21QUEST, do you have a slipper clutch on an SV or are we talking a different bike here?

Jenni, I've only been caught out in the rain once and I rode so slowly there was no chance of a rear wheel lock up! My old Yamaha was so slow to respond to throtle changes it was actually quite easy to ride in the wet, whereas the SV gave the feeling that if I opened or closed the throttle to quickly it would not hesitate in dumping me on the road for my foolishness.

It makes all it's torque very low down in comparison to an IL4 and can easily catch you out. Smoooth is the key ;).

Also, do you know if anvils are bike specific ? Or is is just a generic anvil that is required ??

when i was looking for my anvil, i considered many options, these included-
1. Suzuki SV650 OEM Anvil
2. Suzuki GSX-R Anvil
3. No brand ironmongers anvil

i wasnt sure if it was worth the extra money to upgrade to a GSX-R anvil, especially as i dont generally ride that fast... i didnt think i could use the 'uprated' anvil to its full potential on my commute.
the SV anvil comes in cheaper and from the looks of it will do the job for road use.
however, just before i plumped for the purchase i came across an old anvil that a blacksmith had been using in a barn, he let me have a go and it worked a treat!!! whats more he gave it me at a snip of the price of a Suzuki one!!!!

im thinking about getting a GSX-R one for track day use.

Hope this helps.

I find that if you need to realy hard brake, not to worry about the rear because it is probably going to lift a bit and then lock up anyway.

:shock: :shock: i remember the first time i dropped the anvil, left a 50ft darky and started to fishtail , then dipped the clutch, just like magic it started going straight, got rid of the anvil shrtly after, ive tried throwing the pillion off the back....but its just not the same...

[SVeeedy Gonzales]

Also please note that there are both curvy and pointy anvils and you'll need the right one depending on the year of your bike.

I just use the brakes and leave it in whatever gear until she's doing the speed I want, then I take her down through the gears. Sometimes (though I tend to avoid it for obvious reasons) this is as I enter the bend, or as I'm going through the bend... the torque means you can be a couple of gears too high and the engine will still pull.

Leaving the gear changes until later means that if I go into the corner and it's tighter/less tight than I first thought, I'm changing to the gear I actually need, not hoping to get the right gear then having to change it again when I realise the corner is slightly different to my first impression. Or maybe I just like doing one thing at a time :D

Repeat after me, you cannot lock the rear wheel with engine braking...

Hello Northy. I knew you would say :) :wink: . Cos you can :wink:

I suspect he has the same one that everyone else with an SV has, it's fully adjustable and is controlled by a lever fitted to the left handlebar.

Only if you're stalled, and that doesn't count ;)

On an SV650 :wink: .

Ok then :lol:

... and you would be wrong :^o .
Darn , Can't anything get past you :roll: :) . Spot on

[northwind]

There's a company making a production slipper for the SV now, if anyone's interested... IIRC it's around $900US though.

I think JHS sell them as well or atleast was looking to. I'll stick with the standard one though :wink: .

i dunno what all this engine breaking milarky thing is all about....

i personally dont get it and i ride hard (or so the missus says)

i went from a gs500f with engine breaking and never got caught out on that too.... to be honest theres no diferance....

the only time i notice it is when i am riding in to low of a gear to start with.....

i am wondering if the noobs notice it more cos the bikes got lots more power and torque then the das bike they learn on....

i noticed that teh bike i did my das on was lots more under powered, but i realised the same gearing aint gonna work on a bigger bike....

[jenni]

possibly, but i didn't do das so its been a straight jump from 125!
