The Christini AWD 300 2x2: How All Wheel Drive Works on a Dirt Bike

Рет қаралды 2,187,696

Жыл бұрын

Christini’s AWD Dirtbike uses mechanical all drive system that delivers power from transmission to front wheel. In this video, we will demonstrate how the AWD System works on Dirtbikes. It was created with hardenduro riders and races. This dirtbike 2x2 has been tested at Erzberg Rodeo, Last Man Standing, and many other tough enduro races around the world. In the year 2004, Yamaha also produced an AWD Enduro bike called the Yamaha WR450 2-TRAC 2x2. I like this Christini system because it can be mounted on KTM EXC 2 Strokes and GasGas 300, which is amazing because you get a 2 stroke with AWD 2x2.

@onecookieboy Жыл бұрын

I agree with @agzrele, the parasitic power losses from all of those bevel drives, sliding shafts as well as the drive shaft to the front forks and chain must rob the engine of a lot of power, not to mention the maintenance aspect of it. Furthermore, the setup would add quite a lot of weight to the front of the bike, which is not ideal. We have a 2wd ebike here in New Zealand (mostly sold for farmers or hunters needing the extra traction in muddy conditions) and they report that having a driven front wheel makes the handling rather hard to manage, I imagine that this system would be even worse because it's purely mechanical so if the back wheel loses traction so does the front. It's an interesting engineering concept, but more of a novelty than anything. At least if you used a hub motor and battery, you could mount the battery in the rear, put a controller almost anywhere and the hub wouldn't add too much weight to the front, you could also have easily switchable power to the front with a easily built in traction control system.

I bought one, spent thousands on it, rode it 3 times, sold it for a loss. At times it was great, in the mud and tight single track... I thought it was worse. Had to remember to make sure the front end was pointed exactly where you want to go, every time the front end comes back down or it will throw you into the bushes or over a cliff. Different kind of riding, like changing from 4 stroke to 2 stroke... you have to ride it differently.

In certain situations these bikes are amazing, dry days evens out the field and they are a lot heavier. But fun none the less. Biggest issue is keeping the front end and bearing happy.

Fun thing I've seen, someone back in the day made a 2wd by adding a hydraulic motor - the rear chain essentially drives a hydraulic pump which then moves the front wheel when needed. He briefly mentioned hydraulic pumps in his video, but not how they worked in this respect - I'd say it's as simple as a front electric motor... Without needing electricity

@DigitalJedi 6 ай бұрын

Hydraulic is definitely an interesting idea to drive the front wheel. With how powerful modern electric motors are and how efficient generators or even alternators can be though, I think going electric is a good move. Instant torque front and rear would be something else, and for a full electric setup would be as simple as dual hub motors.

This is definitely a new take on 2WD bikes. I had a Rokon TrailBreaker back in the mid 1970"s. Rokon's are not "dirt' bikes though. They are slow and steady trail bikes for going where there is not a path. I think that they will go places the Christini will not, but the Christini is light years faster. The drive system was very different, too. The 2WD is full time and only cuts out on the front when the spring loaded clutch slips (by design). This seem very cool, and I wish it had been around when I was an active dirt biker, 30 years ago. LOL

Battery weight likely the main issue, but the tech is growing very rapidly and I'm sure the military is on the cusp of it if anyone is. Enjoyed the video 👍👍👍

I tested the Yamaha 2-Trac for Australasian Dirt Bike Magazine, and the story was re-printed in one of the US mags as well. I liked it, but many of the top riders that rode it didn't. I think this may have been because it tracked so well in slippery corners rather than sliding. They were all used to steering with the throttle and back wheel in those conditions. Only 250 were made, and only 20 came to Australia, none went to the US. At least one of the Aussie 2-Tracs was sold by a dealer here to somebody in the USA. They couldn't be road registered in Austrlia as they did not have a compliance plate and were twice the price of a conventional WR450. They also came with top of the line Ohlins suspension front and rear and an Ohlins steering damper.

It looks pretty cool but just remember those extra 6 kg (13.2lb) are mostly rotating mass with a fair bit of it being unsprung weight. Both of which will make if feel heavier then 6kg (more like 10-15 kg) and dramatically effect handling. I also wonder what effect the two drive shafts have spinning adjacent to the engine and having a torque effect on the steering would do to over all handling? All that being said bike set up is a game of give and take to improve in one area you usually have to give up in another area and for all the negatives I’ve mentioned you are gaining traction which in some circumstances is very hard to come by😀 Hopefully one day i get to try it out

2 of my 3 electric bikes are All Wheel Drive. Its 2 independent system. 2 Motors, 2 controllers, 2 batteries, displays, 2 accelerators, one for each thumb. I also have 3 motors on one my bike which is 3 everything. 2 thumb-throttle on the right and one on the left. The 2 on the right are the rear hub motor and the mid-drive motor and the one on the left it's the front motor. I used many combination. The thing with all wheel drive is the front wheel is directional. So at low speed when you are turning for example you want to be careful and use very little throttle on the front motor because the bike will pull the bike this way and you will go the other way. So basically when I turn at low speed, I only use the rear motor and when I get more straight I add the front motor. At least in the beginning when you learn and you are not used to it. Note that my experience is on the road and snow. Off road folks have more skill will probably get that in seconds. Humbly!
