Hmm.. Just a fascinating bit of engineering it is..
Not as much as I remembered from my 450 testing. I was just a bit disappointed as I was hoping it would be a magic wheelie machine but I'm still only average. Gino is really the one who needs to test it on one wheel as he can go through all the gears.

As far as the bike being resistent to turning or feeling stiff or tight it's not really there. You certainly notice the steering tighten when the front is spinning and honestly that's a blessing. It's a combination of gyroscopic forces along with the front pulling the bike straight. It's like the bike is always trying to stay in line or follow the front. While it's obviously a limited test the extra weight of the 990 actually seems to temper some of the more lively behavior I felt on the small Christini - such as the tendency for the front to skate or get crossed up and pull off course. Obviously I want more time on it as there's much to learn. Knobbies might reintroduce that.

I'm trying to convince Gino to take it down to the Pine Barrons next weekend and ride it in the PB300 to put it through it's paces. We'd need some better tires but already I know it would be worlds better than it used to be with the smaller wheel set. Right now the only downside seems to be the cost and I think it's worth it as this is a whole new motorcycle.

Its good to hear your happy with it Gregor.
But now you've got yours I hope it doesn't mean you'll be putting the grease gun down.

Should work at least as well as rolling up the windows.

Nada space on drive side

Need to upload pics to Smugmug.....dammit.

OK cyborg, you start working on getting the 690 crated up to ship to Chris. It'll be winter weather soon over in the PNW, you won't miss the bike till next fall. I'll start working more overtime.

There are some left side no bodywork pictures on the first page of Bartron's build thread...

http://advrider.com/forums/showthread.php?t=666269

Please make the AWD conversion compatible with the extended range gas tanks from RR and Safari and the Scott's damper--I know the AWD system might eliminate the need for it--but this bike usually benefits from a damper, it might benefit from a double dose--lol If the airbox has to go, see if you can fab up a way to retain good water fording depths.

OK Gregor, give Chris a break on new projects for a year or so--you won't really need that amphibious/semi-submersible conversion until then.

OK, that's all sorted then. Just have to sit back and wait for the results. Easy.

Who else wants an AWD conversion for their 690?

I've been wondering: non-directional front tires? or if directional, which direction? or maybe it is not an important consideration?

Not enough power up front with the Christini kit to justify a full paddle tire. Some 100% off road knobbies or an AMA "paddle" tire should be enough.

My bikes on the other hand have no power limits up front. 2x paddles would be awesome (with a BIG front fender) but off power, steering is likely to be crap.

Speaking of odd tires, I've been considering putting a rear tire up front on my bikes. The extra rolling resistance shouldn't be a problem with AWD but bumps likely will kick the handlebars more. I'm hoping the deeper tread, lower ground pressure, and larger air volume will make braking more confident. 'Cause having the front wheel squirm when braking on sand/mud is jarring compared to the point-n-shoot performance of an AWD on the gas.

Looking forward to the video Sakurama. That's a skill I'm not too good at.

Wish I could, but it never really snows in the Seattle area, or much anyway, and I ride year-round. Besides I have another project for it I have to do first. There has to be some snow-bound 690's that really are parked all Winter/Spring but then they would also want to have AWD too. Problems, problems.

Like Pyndon said, these 690's are packed tight! Not a lot of room to work with unless some other mods to other parts like airbox, etc. Hmm, would take some fancy engineering for sure.

Wow, that looks pretty crowded! Any retrofit kit wold require some internal spacesaving changes too. Who knows, but I do have a full plate at this point. Maybe sometime next year if people are truly interested.

Nice work but I genuinely mean this, who's bike is it anyway? There is so many cool people involved, I've lost track.........OK, I could go look and I think I vaguely remember.....



PS. I have a spare KTM690RR in the shed, that would make a cool AWD project, let me know when you guys get bored

Are AWD motorcycles allowed in the Dakar?

No fishtailing unintentionally in the dirt? Traction and control on a stupid powerful dirt bike?






Oh yes, I will have AWD on my 990…

Hmm,,

1. I wonder if you could get a AWD discount on it.. for Insurance.
2. I wonder if they would even know how to insure a 2wd dirt bike.
3. I wonder if they could insure it for its full value, at least progressive has accessory insurance…
3. I wonder if its best not to taunt the dragon.. LOL

And since the mental wheels are turning...

I rode some Northern Baja a few weeks back. The 950's and 990's on the trip were fishtailing through the dry sand rivers at lower speeds. All these bikes had steering dampeners, and well sorted suspension.

Could AWD be the big Adventure's "Holy Sand Grail"?

There is a really simple cure for that, much more economical than AWD..........open the gas and go faster
