Venhill quick action throttles

[DaR1]

I wouldn't recommend it for the road - slow speed control and small throttle movements in heavy traffic would be a nightmare.

Thanks Gaz

I dont quite agree Gaz.  Always had them on road bikes and they merely require better control.  Its down to the operator.

A QA throttle teaches you better throttle control.  Sure it'll kick your ass if you a hamfisted monkey but it will teach you a great deal about throttle finesse assuming you can master it.  They dont suit everyone fwiw...

Undoubtedly, but there comes a point where it's not worth it. I would argue there is no benefit to road riding - how often does someone on a 1000 use 100% throttle? From magazine experiments I've read, not very much (I think it was rare to go over even 25%). My R1 certainly has more power than I could ever use, so going from 1/4 to 1/5 or 1/6 turn isn't going to make a blind bit of difference to me.

I can understand for people chasing that extra half second off their laptimes, but I just can't see reason or necessity on the road; I can see extra risk, and TBH there are already enough dangers on our public roads without adding to them.

Theres no point on the road - but the transition backwards and forwards is quite difficult - so stick to one and you'll be fine.  Afterall who couldnt benefit from better throttle control ...

for the road,i wouldn't fit one especially,but wouldn't take it off if i there was 1 already on.

as for track,it does make a big difference,and does shave those all precious seconds off

The 08 R6 comes with one as standard so I left it on

DaR1, if you don't want a full on Q/A throttle at 1st, then you could look at a RME (Robby Moto Engineering) Quick Action Throttle, they come with 4 different cams and are quite easy to swap over... double the price though but very nice bits of kit...

I've had RME, Euro Racing and Venhill.  I'd always get the Venhill now but I don't ride on the road...

(Euro Racing offer, 3 cams but they are not completely round, this can lead to a slight kink in the cables)

[Seton Tuning]

Just to confirm something.  The single cable quick action throttle is only for track use.  You need a 2 cable throttle to pass the MOT.  We would always inform customers of this when they purchase one.

[Southerner Oop North]

Hi Phil is that actually in the wording of the MOT? I had a bike MOT'd recently with only one cable and it passed?

[Seton Tuning]

After reading your question I decided to double check with a registered MOT tester and they confirmed that a single cable will pass the MOT, providing the throttle returns of it's own accord.

Sorry Charlie didn't realise it was you

Thanks for confirming

There is no way in hell i will ever ride a bike with only one cable 

seems a daft thing to do..

everbody to their own, but there are more people running single cables than those who use twins, in the paddock.

the only reason to have two cables is to protect against a snapped return spring on the carbs/throttle bodies. If you have two cables you can physically turn the grip anti-clockwise back to the tickover position, whereas with one cable you would have to pull the clutch in and hit the kill switch.
Either way would cause a certain degree of panic, so you pays yer money ,
or fit a secondary return spring  like they do on some rally cars

So that's where you disappear to for 30 mins after every session - you're doing market research on throttle cables

well now, what an interesting debate, I'll throw these two nuggets into the mix:

first off, I used to own a bandit 600 which I actually quite enjoyed (wide MX renthals, single cable QA throttle, ignition advancer, K&N etc). however one day I was riding back from bristol on it (actually in quite similarly cold and icy weather as we have at the moment, just with a bit less snow) and you'll never guess what happened as I went to overtake a car, yes thats right the return spring snapped and I was left going down the road in about 4th gear with the throttle pinned open. I actually ended up panicing and hit the brakes which was a big no no, and ended up taking the top of my knee caps off on the supergrip that was covering the middle of the road (you know the nice red sandpaper style stuff) as I was only wearing jeans with my kit. On the flip side as has already been mentioned, if I'd hit the kill switch and pulled the clutch in I'd have been fine but it was so cold I had lost my concentration and reaction times etc.

to be honest though, it wasn't the best maintained bike before I got it, and I wasn't much better when I had it either, so as long as you keep your bike uptogether I can't see any reason why you wouldn't use one for safety reasons. I also think that the extreme cold had something to do with it as well (it was about 0 degrees C or so that day and was getting a lot colder in the evening before I left so could have been -1 or -2), as metal is more brittle when it's cold and I had ripped the throttle open as I just wanted to get home.

secondly, on the subject of road riding with a quick throttle, I actually made one for my GSXR last year as I was fed up of having to reach around the throttle to get on the gas properly and now have only 1/7 maybe 1/8 of a turn to full throttle (the bandit one was only about 1/5). When I first made it I did worry slightly about riding in town and threw traffic etc. even though I was already very smooth with the throttle, but I've actually found it's made me a lot smoother since fitting it, and I actually find it easier to sit at a constant speed (for when I have to sit at the speed limit behind a copper while I work out how to pass him legally).

So there you go, single cable can be bad if you don't keep your bike up to scratch and your really really unlucky and there's a blue moon out, but even through all of that they still get a thumbs up from me.

[Sheepy]

Put it this way...

I have removed and stripped choccys R6 carbs.. there right next to me next to the computer,  the fact you can hardly hold the throttle open due to the return springs..

guess how many return springs there are closing the throttle butterfly?

1?
2?

there is 7 in total so to have every one of them break... well lets just say, its highly improbable
