All-wheel drive motorcycles are nothing new or unusual. They were created quite a long time ago, and similar vehicles were used mainly to participate in rally-type motorcycle racing. First of all, this is due to the fact that such models cope much better with turns at high speed.
However, unlike four-wheel drive vehicles, a four-wheel drive motorcycle does not have a full-fledged driven front wheel. On the most common models of this type from the Yamaha and KTM brands, only 20% of the power is transmitted to the front wheel. Christini's company was able to create a bike with 50 percent of the power transferred to the front wheel, but this greatly increased the weight of the vehicle. What can domestic models oppose to all this? We will talk now about all the advantages and disadvantages of the Ural all-wheel drive motorcycle .
When did the first all-wheel drive moped appear?
The model was first demonstrated in 1924 in Britain. For many years this was the only copy. Only almost 3 decades later the famous Rokon bike was made. Its operating principle was based on transmitting torque to the front wheel using two chains.
Despite the fact that there was no suspension, the motorcycle felt great on difficult sections of the road. The weight of such a vehicle did not even reach 100 kg. This motorbike is widely popular in our time .

Not bad, maybe you can translate
the m50
. It drives cool, especially if there is a differential lock, I have it on the K-750.
Beast machine! BUT the locking must be turned on off-road - like on jeeps, because the driving pair of wheels rotates with the same torque (both “row” equally) - in general, this is the whole point! When the lock is turned on, the cross-country ability is at the level of the snowmobile. Well, on asphalt with blocking, you can easily roll over or not fit into the turn! If it is disabled, then it works like a regular differential - on a Zhiguli, or a Muscovite (a car with rear-wheel drive and an axle) - but otherwise it works like all wheelchair users! slavets
I had a Dnepr-16 with a wheelchair. One significant minus is that it won’t travel without a stroller, because... There is no differential lock, so I had to change the pendulum and gearbox. for m50

And this drive is durable and how to find out if it has a lock and if it is on the IMZ, but spare parts are difficult to find??????????????????
Easy_rider_rus
for Ryder
: There should be a lever on the top of the gearbox if it is

Well, they haven’t made them with locking for a long time….
And without blocking, who has it - what's the shit on it? MadFox
Wheel drive for strollers appeared quite a long time ago. BMW Sahara motorcycles were in service with the Wehrmacht during the Second World War, and MV-750s were produced for the Soviet army. And from the beginning of the 90s, similar devices began to be produced for the general public at the Kiev and Irbit motor plants. However, one should not be overly deluded by the fact that they have high cross-country ability. Even when shod with cross-country tires, motorcycles cannot be called all-terrain vehicles. There are two reasons: lack of low-end torque and the presence of a non-locking differential. Not only on slippery ground, but also when turning, as soon as one wheel gets free, it begins to spin wildly, and the other, accordingly, stops. And it turns out that during a right turn (the passage of which, if you remember, is facilitated by the acceleration of the motorcycle), the movement slows down and the car may even stop. For someone accustomed to riding in difficult conditions on two wheels, riding such a motorcycle is simply dangerous. Devices with a leading wheelchair also have “advantages” - otherwise they simply would not be made. They are easier to drive on sand. Further, when driving on asphalt long distances or when driving with a heavily loaded stroller, you don’t need to put a lot of effort on the steering wheel to move straight. Believe me, this is a lot.
Taken from www.biker.ru thanks to Hub.
+ I can add from myself that I liked driving on the highway without a sidecar drive more - the motorcycle is easier to control and more maneuverable. IMHO, differential locking is a must; without it, there is little point in driving the stroller. Ryder
And if you buy it without blocking, and then install it, and is it even possible to buy it?
For MadFox: Thanks for the info.
This is my tenth year of flying with a stroller, but without a drive, and I think there will be no difficulties. ziurke

Is everything really so bad?
For some reason I didn’t want to buy it, but which bike is better for driving on off-road roads, a regular one with a sidecar or one with a drive but without a lock? sheih
for Ryder
: Buy it, there will be two, one for the field, the other for the city.
Ryder
So, I already have one, but without a drive I want to make a civilian out of it alone, and with a stroller I like to fly

For harleych: They offered me the Ural, not the Dnepr, and if they had offered the Dnepr, one would not have taken the spare parts, it’s impossible to find them.
And thanks for the photo of Tsundappa, a real MOTOTRACTOR!!!! Harleych
Ural with drive is expensive.
There are two types of drive: a symmetrical differential or a switchable stroller without a differential. The Dnepr is similar in design to the German. I think the gearbox guts will fit from the R-75 and the MV-750 with a locking gearbox is the best Ryder
Can you show in the photo how everything is done there
Unforgiven
I have a Dnepr 16, an awesome motorcycle, but you can’t fold the sidecar without replacing the gearbox .
Another problem is the inability to disable the differential. But compared to the advantages, these disadvantages are not so important Ryder
Why bother throwing it back?
VER
for Ryder
: Urals with sidecar wheel drive began to be produced recently, somewhere in the early 90s.
Such motors were produced at KMZ MV-750, MV-750M, MV-650M for the military and Dnepr-12, Dnepr-16 for the civilian version. From 1964 to 1973, the main army engine of the SA was the MV-750, it had a switch-off differential. drive because gearbox 6204 had no reverse speed. After 1973, such differentials. drives were not produced and the MV-750M (modernized) and MV-650 already came with the MT-804 gearbox with reverse speed. I have the same MV-650 and Dnepr-11 engines, all the same difference in the drive. And I can judge the cross-country ability of one and the other, where I couldn’t pass on 11 on the MV without problems, and if you hook chains, it’s just a tank. And the speed of the Dnieper is lower and at low speeds the dynamic characteristics are better than in the Urals (I haven’t seen a Ural with a drive, I’ve read a lot) But I think the MV-750 is even better because The engine is even less revvy. And in winter, cross-country ability is much higher, 11 with a loaded cradle does not go well in the snow, and in other places it doesn’t go at all. The picture is the same on the sand. Hirurg
bullshit is all about changing the gearbox, etc., I have an MV-750 with a stroller without blocking in the mud like on a tank, and you recline the stroller, put a bullshit on the stroller shaft in which the cross is held only to it, a squiggle is screwed on, which is screwed on the other side to the pendulum, In general, the wheel does not spin very quickly, but here it is 2 times faster, since the differential is
Unforgiven.
Where did you get such a thing to recline the stroller?
Unforgiven
I will sell my Dnepr-16 for 750 hryvnia.

:Don’t be smart about how much in rubles??? for

Approximately it will be 4400 rub.
What about the all-wheel drive Ural?
In principle, such a vehicle has never been officially released. Thus, it will not be possible to purchase a production model. However, one Russian craftsman managed to independently create a Ural with a wheelchair drive, which copes well with difficult sections of the road. A radiator from a VAZ 2106, as well as two additional electric fans, are mounted on such a vehicle. You will also need a 63 amp battery and a homemade transmission mechanism.
It is worth saying that this version of the Ural wheelchair drive is the most universal and allows you to achieve excellent cross-country ability and reliability. As a result, many began to inherit and copy such a creation, so that now you can see a fairly large number of similar vehicles.
Unfortunately, manufacturers do not always listen to the wishes of customers, so the Ural motorcycle with a sidecar drive has not yet entered mass production . Well, perhaps in a few years they will begin to produce it en masse, but for now we should be content with homemade models.
Homemade wheelchair drive for a Ural motorcycle
MAIN TRANSMISSION AND STROLLER WHEEL DRIVE MECHANISM FOR OFF-ROAD MOTORCYCLES “URAL”, “DNEPR” All-
terrain motorcycles have an additional sidecar wheel drive. On a motorcycle. “Dnepr-16” has a stroller wheel brake mounted on the right cover of the stroller wheel gearbox, and also uses a different design of the transverse driveshaft - the rigid pipe is replaced by a relatively thin steel rod.
The main gear with an asymmetrical cylindrical differential is designed on the basis of the main gear, which is used without a differential. Cardan transmission (Fig. 4.38),
The drive gear, bearings and housing are taken from the base model of the motorcycle. The cuff and its cover are the same. The left hub spline is the same as on the base model. All connecting dimensions of the main gear to the wheel remain unchanged.
A differential and a gearbox are attached to the crankcase, which form the main gear of the off-road motorcycle. The main gear is connected to the stroller wheel gearbox by a transverse cardan shaft with two rigid hinges. The differential consists of the following main parts: driven gear 8 and cup 25, which form the differential housing, two hubs 13 and 28 with ring gears, two wide 7 and two narrow 24 satellites and their 4 axles 5. The differential cup is connected to the conical driven gear gear using two bolts secured with bent washers and two pins pressed into the protrusions of the cup and freely entering the gear hole. These pins center the positions of the two parts. The differential parts are located in the crankcase 6 9 (Fig. 4.38). The right hub 28 ends with a splined rim on which the drive gear 29 of the gearbox is mounted, secured by a retaining ring 1. The drive gear is connected to the driven gear 27, the shank of which is connected through a cardan joint to a transverse cardan shaft, which goes to the stroller wheel gearbox. The housing parts of the main gear are connected through cardboard gaskets. Maintenance of the main gear and gearbox consists of monitoring the oil level and replacing it in a timely manner. The oil level is controlled by dipsticks with two lines, which indicate the maximum and minimum levels. The type of oil and the frequency of its replacement are the same as for the base model.
The universal joint bearings are lubricated with a syringe through grease nipples screwed into the crosspieces. To lubricate the bearings, you need to unscrew the caps using a radius wrench.
It should be remembered that the cap on the main gear side has a left-hand thread, and on the gearbox side it has a right-hand thread. The movable splined connection of the transverse propeller shaft with the universal joint fork on the main gear side is also lubricated.

Advantages and disadvantages of the vehicle
Among the main reasons why the Ural with a leading sidecar is very popular are:
- excellent cross-country ability (the probability of getting stuck anywhere is almost zero);
- good load capacity;
- improved management;
- smoother and softer dynamics.
But the Ural all-wheel drive motorcycle also has some disadvantages. First of all, there is a more complex chassis design. In addition, there is no way to detach the stroller. At the same time, there are clearly more advantages. Especially for those who love driving on difficult roads.
Another domestic model
Dnepr-16 is another Soviet bike with a sidecar. The model stands out thanks to the rubberized stroller springs and a load capacity of 200 kg. Such a vehicle will be an excellent option for leisure and work.

Homemade tricycle from the Urals
The main advantages of a tricycle based on the Ural:
- good handling;
- the ability to develop sufficiently high speed;
- high power;
- comfort during long trips;
- a spacious body for transporting cargo weighing several hundred kilograms.
The predominant part of the components belong to motorcycles; the engine for the trike is suitable from a ZAZ-968. The most labor-intensive process is making the frame. In the design, it is a kind of connecting link on which all components and parts are installed.
A short summary
So, all-wheel drive motorcycles are indispensable vehicles for those who often need to travel on difficult roads. They are distinguished by increased maneuverability and reliability. Among our models, the Ural with all-wheel drive stands out here .
Such a vehicle can easily overcome almost any section of the road. However, the bike did not go into mass production, so you should either buy it on the secondary market or upgrade it yourself.

Homemade ATV from the Urals
Heavy Ural motorcycles are not very popular. One of the reasons is the huge consumption of gasoline. Many motorcyclists and bikers are not satisfied with the large dimensions of the Urals. Despite this, folk craftsmen are interested in such motorcycles. Points such as the presence of reverse gear and a fairly powerful four-stroke engine are very tempting in terms of converting an old Ural into an ATV. Its cost is ultimately much lower than its European counterpart, and the engine power is much higher. Such homemade products from the Ural motorcycle will appeal to everyone who likes to create with their own hands.
Design Features
Craftsmen from the city of Barnaul received a successful version of a homemade ATV:
- The Ural motorcycle was taken as a basis; in particular, the frame with the engine was left.
- The reinforced gearbox was removed from the motorcycle of another model of the domestic motorcycle - “Dnepr”.
- The drive had to be made of a cardan type, due to the fact that options with sprockets and chains are less reliable.
- Two pairs of wheels fit well from the Gazelle car. The appearance of the ATV turned out to be rough and uncouth.
The engine power of a homemade ATV allows you to pull a load weighing up to 500 kg. Without a load on an asphalt road, the wheels slip during the start.
The management of Russian automobile factories should think about the issue of producing domestic ATVs and tricycles, taking advantage of the excellent experience, for example, of Barnaul craftsmen. Moreover, most of the components had already rolled off the assembly lines of these enterprises at one time!
Homemade Ural motorcycles can look different. In any case, this technique is impressive.
