Hmmmm...hadn't considered that, but not too sure I'll be exploring that either? :eek1
Why do you think it would hydroplane anymore than a similar conventional rear wheel drive bike with similar tires?
The simple answer is you would have both tires digging for traction and could maintain a higher SOW. And speed is what you need to stay up. Clear as mud.
What is SOW? I went to my old stand by http://www.acronymattic.com/SOW.html and out of 59 definitions only seepage of water seemed close?
Finally got a chance to ride it off road yesterday. The bike worked great, made it all the way to the top of Pat's trail, which is a rocky, steep switchbacked hill climb . About the top 25% was about 6" of melting, heavy snow churned up by 4x4 quads, but the Christini mowed through it, no problem. Even with 15psi in the 50/50 dual sport tires, it easily climbed up the steep switchback trail with rocks, roots and a snow topping.
At the top I rode a ways up the fire road, which was about 10" deep in the untracked parts. It was actually easier to cut throught the untracked snow than trying to follow the quad tracks, which were hard to stay centered in and caused the bike to wag. The bike would spin both tires and just motor through the deep, heavy snow, but it did cause the steering to feel very stiff, like you turned the damper all the way up. Not sure if it was the snow or AWD or both?
The bike felt pretty normal otherwise on the average trails, but a little stiff. I need to adjust the suspension a little more and it is probably still breaking in too. It does have slightly less steering lock than my CRF, but I really didn't motice it much. The drive ration, 64% under drive to the front, seems a little low? It allowed quite a bit of sideways drifting before the front pulled it backwhen flat tracking on Peter Burns road. I think some adjustment there will also make it better, maybe about 75-80%?
Hopefully I will have my Rekluse clutch and hand brake for the next ride. It was weird having to operate a clutch and using my foot to engage the rear brake?!? Some more suspension adjustments should also smooth things out. More to come! <!-- / message --><!-- sig -->
I have one of the 2 KX450F Christinis , I had the drift you mentioned, so I switched the top sprocket near the gas tank to a 15 tooth from 16,,, which left too much slack,,,so I went back to the 16 and added 2 teeth to the rear wheel sprocket. I have been quite satisfied with this ratio.
I'm subscribed to this thread now so I'll be interested to read your comments on the Christini. I use the KX mainly on mountain trails, but plan to Dual Sport it. I just added a Rekluse and believe it's the greatest thing 2nd only to Steve Christini's brilliant all wheel drive system.
I've got the Rekluse EXP and will be doing the install of that, the rear hand brake, and my tall bars this weekend. Pics to follow.
Just an observation . . . I'm amazed at the firmness of judgmental, negative declarations expressed by individuals who've never ridden, perhaps never even seen, a Christini bike!
Their lists of hypothetical/theoretical reasons why the AWD system,won't work (all untested and none demonstrated) remain PROFOUND.
Similarly, Aesop's fox judged some grapes SOUR, without tasting them.
i'm planning to buy a 450ds in the near future.
how are the ergos for a 6'2" rider with a 32" inseam and week knees?
Well said, XDR, but new tech is always derided by some, at least initially.
TDR, I'm not sure what ergos work for bad knees, thankfully!, but it fits me pretty well with my 34" inseam. It also seems to have proper springs for a rider weight af about 200+ lbs?! The handle bar clamps are adjustable front to back in 4 positions, much like a KTM. The seat feels a little like a KTM too (hard)?! :huh
i dont like a close seat to peg ratio, my knee is best less than a right angle
my back side likes a wider seat.
the 450ds looks like it uses crf450x body and seat parts, if thats the case seat concepts has a wider seat
any pix or video of single tracking your awd mc?
Great to see these bikes getting out there and reading some reviews.
Can't wait to get our 450 DS's in to start looking them over and prepping it for our first big test trip in WI.
Going from a 950 to a 450 is going to be a bit odd for me, but so looking forward to it.
Keep the updates coming Pete.
Very interested to see how this works on this bike. Did you get this direct from Steve? I've heard the standard REKLUSE units for the Honda won't work on the Christini 450. I'd rather run the EXP than the Z-start PRO if I can.
This was not the end I simply backed the bike up a little an blasted through and continued on.
Next to impossible to get here without a Christini,,, left everyone behind.Is it lonely, you might ask? A little but too much fun to notice.
No, I got it from Rekluse after I returned the Z-start Pro which wouldn't fit because of the slightly larger diameter clutch shaft. I hear that Steve is making hubs for the Asia Wing motor so you can use a Z-start Pro or CORE clutch? I'm curious to try the EXP too, since I've only run Z-starts in the past. I should have it together this weekend.
Has their been any progress in moving your 950 AWD conversion closer to production? I haven't noticed any updates on your threads for a bit. Have you given any consideration to converting a 650 class bike to AWD?
A note on increasing the front drive rate.
As mentioned gearing the rear sproket lower will help close the gap and engage the front earlier, my 530 had a 13/9 front and a 16 tcase input, 45T rear for about a 67% underdrive rate, going to the 52 rear sprocket raised it into the 70% range.
Then I tried the 13/10 front countershaft and 15 tcase input and am at about 80% (same length 420 chain), great in the deep snow on studs, but tends to climb out of the rut a bit too early as it hardly takes any rear spin for the front sprags to engage...
I may go back to 13/9 and 16 for summer (offroad) conditions. Put a 49 on for local dual sporting.
Ya, He's offering custom Rekluse Z-starts for these. Can't wait for the EXP update and see if STOCK fits. Getting all the little odds and ends sorted for the bike build-up when it arrives.
I've just been swamped in the shop and sick the last few weeks. More important things to do to catch up than dig through 100's of pics and post more, although I really want to.
The AWD 950 ADV is done and working great. I've been talking with Steve about maybe doing a batch in the future with some custom parts built to my specs, but that won't happen until either of us have more time to sit down and look this over. I want an AWD 950 SE so bad now, so I can see myself building more in the future, it's just when?
If I can see any place on Version 2 to make it better, I want to do it if I can.
I have thought about doing other bikes, it just takes someone with cash to say do this to my bike at whatever cost....
Then me to say, OK, I'll stop riding for 6 months while I sort this out and build it.
I don't have the R&D time to do it for free.
The BIG Adventure bikes are great and would be helped out so much by this system. It has been awesome on the KTM 950. Instead of having go full throttle up tuff stuff and bend rims or what-not, I can pick and choose my lines better and slower for safer travel. Plus 2-wheel roosts with 100 HP is so much fun.
