Im not to sure if this is the right place to post this but ill try anyways.

Im looking at getting a quad next year ( yamaha raptor 700R ) and ive heard these things can do 0-60 in just over 5 seconds stock ! ooft !

Thing is ive heard theyr really easy to do wheelies on as only RWD but if your racing them say in a straight line surly youd want to see where your going and try and win the race so my question : how do you keep a powerful race quad from wheeling but yet also have enough throttle to get such quick accelration like the 5 second 0-60 ?

Surely 5sec is the actual 0-60 and not the theoretical 0-60 of full throttle from the start?
0-60 in 5.1sec = live
0-60 in 4.9sec = die Very Happy

Either way, I rolled a Polaris Diesel Laughing

Why would 4x2 make it easier too wheely, other than nose weight? All the big engined 4x4 polaris we had in would put you on the floor?

Thats why the 6 wheeler was better Laughing
Untill you came to a corner Sad

i just thought with all the power to the rear it could just kick the front and and could flip ypu

ive seen videos of guys with turbos / nitrous on quads but just wondering how to keep the front end down when going hard on the throttle

Yes. I have a Polaris Sportsman 800 Twin efi. 4x4 with front and rear lockers. It is a utility quad, and it can go 0-60mpg in 8 seconds. It is rather rapid. Not really used on the road, mostly used for scouting out new greenlanes or smallholding work.



This pic is one Ive pulled from the net, but it is the same.

yes its possible but you need lots of skill and know when to change gear at the right time,some big bikes can hit 6omph in 2.5 secounds and they waigh less than most quads and only have one rear wheel to put all there power down with.

Hi,

Road going quads should be front wheel drive only. That way they couldn't lift the front wheel ..... except in reverse.

Acceleration is limited by the Coeficient of Friction between rubber and tarmac,. which in theory, cannot exceed ONE. So what does that mean in lateral acceleration? 1st scond = 32ft/sec. 2nd sec = 64ft/sec. 3rd second = 96ft/sec ....... and 60mph = 88ft per sec. So something under 3 seconds is about the theoretical limit of acceleration, 0 to 60.

Dragsters have a jockey wheel under the rear end. Ballast tractors have cast iron Avoirdupois tied to the front bumper.

not want to sound rude but have you actually seen one?

the engine configuration by the majority of quad amnufacturers set the RWD as std.

the acceleration of these quads will allways be fast as the power to weight is high, in a straight line they are stable and easy to manage but this is all dependant on the amount of throttle you apply. the same as with a car. the problems occur when you corner, these if not carefull will try and tip over when at speed so leaning off the inner side is needed.
the government decided that these are a safe method of transport but when you ride one it is very apparrant that they are not and since the size is small they can be easily missed from view by a truck driver.

they are fun but really need to be treated with respect

Fully agree with that we had a 660 raptor at the garage that was used both on and off road so it off road tyres, the way i used to take corners was either balls out drift it or tootle round as it spat me off a couple of at junctions trying to nip in roads with out having to wait for traffic.

As for keeping the front end down i used to give a little bit of front lean. It was a nightmare at full throttle as it always kept the front end very light steering wasn't responsive as there's no weight there

Hi,

I bought a Suzuki Quad in 1990.. or was it 1992, complete with "street legal" kit, and properly registered. Insurance cost me £55, but I could have got third party for £5.

Local Plod stopped me ....

"Whats this?"

"A tractor!"

"Like a motor bike?"

"No, like a tractor!"

"Oh yes, your front number plate fell off did it?"

"No, tractors don't need front number plates!"

Then he noticed the tax disc, at which point he went into apology mode, said he'd never seen one of these machines on the road before. Let me continue my journey.

I chose a Suzuki, because they had part-time 4x4. A mate asked how steep a hill they could climb. I demonstrated be selecting 15th gear and 4x4, put one front wheel against a telegraph pole, and opened the throttle. Luckily I was able to close it again before the quad got completely vertical. I once used it to pull a Ford Escort up a 1:5 hill. My quad and trailer tyre tracks inthe snow were the only ones, for several days, on the road up the local mountain

My rear axle was solid, but the front axle had a differential. So by removing the rear prop, it would have become front-wheel-drive, and possibly safer. The differential might have reduced tyre wear. ???

After 2000 road miles, all four tyres were smooth as a baby's bum, and it needed a new cam chain, so I sold it to the milkman, who had 2000 acres of common to play on. I did ponder on getting a different set of wheels, so that I could fit car tyres.

I think quads are a great idea, but lethal on the road in their present configuration and power.

quads are easy to keep the front down!! just lean forward! its the same with bikes lean forward and feather throttle!i have sprinted many bikes and a quad its easy! just takes practice.

as for quads being dangerous yes they are if a plank rides them but if you know what your doing (the only way with any vehicle in my opinion )then they can be used with in there limits safely.

they are not a lotus so dont try and corner them like one!

Hi,

On a bike, you lean into corners.

On my Quad, I found it best to shift my bum over to the outside of the bend. This seems an unnatural way of doing things, but the theory seems to be that with NO differential, the machine has to skid round corners. As centrfugal force throws the weight onto the outside wheel, there seems to be little point in putting weight over the inside wheel ..... so best help the inside wheel do what it wants to do - lift. Of course this does limit the speed you can get round corners. I never tried drfting it.

A problem I found was getting round a particular hairpin (tarmac) with half a ton of mixed concrete in the trailer. The weight on the towball reduced the weight on the front tyres, and with no differential, it wanted to go in a straight line, regardless of being at full lock. My solution was to dismount, grab the front luggage rack, and drag the front end round to the direction that I wanted to go.

......as for quads being dangerous yes they are if a plank rides them but if you know what your doing (the only way with any vehicle in my opinion )then they can be used with in there limits safely.....

I can't disagree with that. The problem is that they are a bit different from what Joe Public was taught to drive. I assume that most people know that somebody who passed their bike test pre-1999ish (???) is licenced to drive a "quadricycle" (which could include a Lotus 6, but not a Lotus/Caterhan 7). I don't think you need to be a "plank" to get into trouble on a Quad .... if you are lucky, the learning curve will only last a few seconds, and you won't get bitten too hard. Riding a bike is intuitive. Driving a car isn't, but everything happens slow enough for most people to survive a couple of mistakes. Quads are out to get you! Would you throw the keys to your quad to your granny, let her get on with it?

Quads need a bit of development before they can become "Plank Compatible", but one day, hopefully, it will happen.

The only ones i've seen round here have been ridden like they were stolen!!
My mate had one and killed it as he went everywhere on the back wheels.

Seems to be quite a few fatalities on quads but having done a rather fun 12 mile track on one recently with what I'd consider pretty extreme conditions, I definitely want one!!

Can't really see the point in having a road biased one with mental power - I'd rather have a really robust one that can go anywhere.

Not leaning into bends does feel weird but I am amazed at what a good quad can cope with - the track I did would have foxed most 4x4s and battered a well ridden MTB.

Before even looking at buying a road going quad you need to check out your insurance situation.
In my area i need a Tracker fitted by the Insurance company & secure ground locks installed.

I had to keep one quad i owned locked always in a secure van when not being used because it was such a thief magnet.
There was constantly pikeys sniffing around.

It went in the end when the van got nicked with the quad in it.
Neither were recovered.

The theft issue is the main reason i've never put much effort into owning one, they attract thieves like magpies to bottle tops!

Someone i know summed road going quads quite simply - all the benefits of a bike with all negatives of a car.
You're still getting cold and wet but don't have the ability to filter through traffic.

You mean all the disadvantages of a bike with all the disadvantages of a car surely?

Pretty much what I think of big trikes, but I'd still like one Cool

However, you can ride without a helmet if you are indestructible.

Lots on the news & in the media today about the EC/EU's proposed changes to road going Quads in the UK.

Main problem is that their ideas to 'improve' safety in the UK is about Road Going Leisure quads.

They seem to think that Working type agricultural quads should be covered by the same rules.

Talk of what just now can be Un-registered off road only working quads that never go on road needing to be covered by the same rules.

Hopefully the NFU and others that talk for Agriculture, Horticulture, & the likes of the Construction Industry will get some sense into things.

Looks like the end will be coming of the easy Quad laws that operate now.
Changes to Import Duties, C&U, Licence & road tax etc.

This is not from today, been kicking about for awhile.

Hi,

In the UK, a Quad has 4 wheels, and weighs less than 550kg (I think). In France it must also be less than 15kW. As I said previously, a Lotus 6 can be driven on a Quad licence (Is that B1?), but in France a Citroen 2CV cannot.

However, in France, an UNLICENCED driver could (maybe still) ride a moped, or a very low powered 4-wheel car ...... no licence, tax, or insurance, though I think insurance is now required.

I understand that in UK, there are plans to require invalid buggies to have insurance. Er ..... are there restrictions on who can drive these invalid buggies?

Hi

Some years ago, I found reference to legislation that allowed use without seat belts on TRICYCLES where the driver "sat astride".

More recently, I have read a comment that the same now applies to QUADS.

????

Idea
You knew that comment was wrong tho, ('Now applies to quads')
because of the fact that Road Legal Quads on sale now dont have a Seat belt fitted & never have had or needed one..
Blue 3 wheel Disabled War Pensioner tricycles were sat inside not astride & did not require the wearing of a seat belt.

Lots of the Law for Tricycles & Quadracycles are based on vehicles that were meant for Disabled use.
(That is how many custom trikes were first built using 3 wheeler cars, not motorcycle frame based.
The Rules concerning the Use & Weight of Quads & Trikes are Different when someone is Disabled.
That includes Age etc.
(The Qualifying factor that concerns the DVLA/VOSA is Receipt of DLA Higher Rate Mobility component.

george

EDIT PS/
602,
missed the question about Mobility/disabled scooters.
No limit on who can use them, but different classes of scooter.
ie Pavement & road scooters.
Rules on over and under 8mph.
Disabled get issued a registration & free tax disc for the heavier/faster ones.
*lets hope that they will all be made to be insured, & training become compulsory, some total idiots of all agres out there using them.*
There are 2 SPAM change people in my area driving theirs (one needed to keep their legs wide apart for a few weeks while on the scooter & a registered drug user on his.
gets his Methadone then goes joy riding.*

Some need an orange flashing light for certain roads etc.
Complicated & becoming full of grey areas like everything else.
I get asked often about it & try to avoid genning up on it or my head will burst.

Hi George,

The legislation that I referred to was pre-quad era, and it specifically exempted "sit astride" trikes. At that time, I was pondering on building something like a Stimson Scorcher Shocked (worth a Google) but with four wheels. There seemed to be no leniency towards "sit astide" four wheelers .... at that time.

My Quad was registered as "Agricultural" (at that time, keeping horses was agricultural ..... but not any more). The regulations required the plastic fuel tank to be changed for a metal tank. Is that still the case? I think it cost £350 for the Street Legal kit, and having it fitted.

Strange things happen in the automotive world. For instance, type aproval requires a vehicle to have efficient brakes with the engine not working. My Moskvitch, bought new in 1971, only had brakes when the engine was running. My wife learned the hard way that Triumph 2000 brakes don't work when coasting down a hill with a dead engine. She drove it over a cliff. Sherpa vans were reputed to have no brakes if you switched of the engine before you actually stopped. No doubt, all these were able to pass official scrutiny. But the Citroen BS brakes are powered by a pump, belt driven from the engine. If the engine dies, or the belt breaks, you don't just have poor brakes, you have absolutely no brakes .... and not even a pedal to pump.

So yeah, does legislation specifically exempt sit-astride quads from seat belts?

the thing I noticed when I rode one for the first time is that if you put your foot down on the ground, like on a motocross bike.... you run over your leg.

I have two, a 350cc Yamaha 4wd and a 50cc Suzuki, the Yamaha is quick for a farm quad but feels quite unstable at speed.
My son thinks his is too slow now, but thats because I've restricted it and he hasn't yet worked out how to make it go faster. It will wheely when the restrictor is wound out (ask Ged) Laughing
