Ok - let me put this to bed. Here's the deal with the suspension:

Stefano forks are experimental. They start as a Marzocchi Shiver 45 standard, but have been completely worked over. They have increased stroke, experimental springs, leg rods made with a special steel, and development version of a double internal cartridge system. Basically, they are the development mule for a new off-road version of a patent-pending suspension system presented by Bitubo at this years Eicma. It's not something that is currently on the market, and I haven't the foggiest if or when it will be.

Oh, and here is some motoporn ... er, pictures of what it will look like in final trim, and some more of it on the mule:

Rob, thanks for clearing that up.


This picture makes my rear shock bolt cringe.

Looks to me that you would be better off just going with the Hyperpro kit or the Bitubo - TT-O, front fork cartridges Kit and a rear spring.

I would be tempted to take the stock forks and rear shock to Percision Concepts or some other MX suspension specialist and see what they say about 'em.

As far as price, you cant go wrong with the Hyperpro, as long as they make something for fat guys like me (220lbs)

I still want to know about their shock bolt.....

I have the report in Italian, and I'm doing my best to translate it using my basic knowledge of the Italian language and web-based translation services. Here is what I have so far:

Quote:
Starting from the already good BMW F800 GS, Bitubo has changed the entire suspension system to make it perform better in off-road use. Bitubo, with this special motorcycle, has officially returned to off-road competition, and has developed a new sealed cartridge system with adjustable return and preload compression, mounted directly within the confines of the original while the stems have a DLC covering which improves the smoothness.
Special Marzocchi based front suspension that is 6CM taller than stock. He preferred not the raise the motorcycle more because
Quote:
it would have given the bike greater sense of heaviness, increased weight transfer, and slow down jumps just to gain a bit of maneuverability.
Quote:
The mono rear shock is all new and is entirely designed by Bitubo, this is the CYU XXF 31 with a 16 mm adjustable stem extension, compression, high and low speed, preload, with separate tank.
New brakes were installed - a Braking Wave 300 with special pads in front, and a wave rotor in back too. Braking is now softer than stock, but it's good for off-road racing.

The wheels were replaced by an Excel setup. Rim widths were altered from stock - 1.6 front and 2.50 rear. Tires are were IMF Enduro Mitas 14/80 x 18 rear and 90/90 x 21 front. This made cornering extremely quick, but the motorcycle unstable at high speeds. (170kph) He should have chosen different size rims, but it went ok anyway. :)

Gearing was changed significantly, but I can't seem to understand how so. Looks like 1 off the front, and 6 off of the rear (but that doesn't seem right...) He spend the vast majority of his time in 2nd gear during Erzberg, and plans to go only 3 off the rear next year.

The exhaust system was the QD Titanium Twalcom exhaust, and he had the QD replacement EDU installed as well. Power seems much more balanced and started around 1600 rpm as opposed to 2200 rpm. It really helped in difficult passing situations.

Handlebars were original, but raised 1.5cm to help with riding while standing up.

The saddle was a reworked high-version stock saddle. The reworking was done by Dalla Valle.

The footpegs were repositioned, hardened, and widened. No details beyond that. The tail section was removed.

The electrical system largely remained original, but all of the hand controls were significantly modified. The horn and started switch are all that remained. The gauge cluster has also been removed and replaced with a road book holder. A transponder was installed.


The F800GS overall was excellent, but not perfect. It was fast and responsive, had excellent power delivery, and was sure footed - especially on slippery terrain. It was not however more stable and precise than an HP2, and was not as quick as a KTM SuperEnduro. It was however a good mix of the two, and was less fatiguing to ride. (or not fatiguing - can't tell)

It was slightly difficult to control during high speed corners due to the abrupt on/off of the gas.

Engine braking was also very marked, and it tended to be very front biased in large jumps. You need to adjust your driving style (like other 400lb machines) to take this into account. Jumps over 1.5 meters are very hard on the shock absorbers. (Stefano notes that he also has the stock suspension set soft as he prefers to have more control in the corners -- he's slow in the jump but more than makes up for it in the corners)

It also does well in hill climbs - he compares it to a ski lift. :) The decent is a pleasure on the bike as well. The fake tank is an impediment though.

The clutch is great as well - it felt perfect and help up during the the rally.

Overall, the bike moves well - very well.


I'm 98% confident the above is correct. I can forward on the document for a more direct translation to anyone who can help.

Thanks for having a go at the translation - really helpful to hear how it he feels it compares to the HP and SE. Particularly as some of the stats are pretty close to my HP, apart from the power So I wonder why he doesn't make any reference to the speed difference compared to the HP? Maybe the gearing make it accelerate faster with a reduced top end... Although I thought top end was pretty important for the prologue...

I thought I knew more... now I think I'm just more confused

maybe i'm spoiled. i can go ride in the sierras and tangle myself up in twisty rocky technical singletrack for days on end. i can head out to the desert and climb really long gnarly hillclimbs or roost down arroyos full of head size rocks or just hold it wide open on a lake bed. so i don't have to pretend that riding a dirt road with a freeway next to it, or a muddy doubletrack with fences every 200 yards, or something that looks like an abandoned gravel loading station is actually worthy of being called "off road riding."
Actually maybe your right and everyone out here who needs a big adv bike to get to the dirt is wrong. So you must tow your bike to the Sierras..

Honkey Please!

honkey when i drive by you in my truck on the way to the trail? sure...

look, i mean no disrespect to the folks who rip out huge miles of pavement then take the same bike offroad. my point was that there seems to be a segment of the population that considers big bikes like these the "ultimate" in dirt bikes, and i was questioning just what the definition of "dirt" becomes once you fall down the rabbit hole of that logic.

i am totally in love with big multi-cylinder bikes that have a ton of travel. i also love the idea of getting myself into all sorts of trouble in the dirt on these overpowered, overweight pigs. but there is a really broad definition of "dirt riding", and i guess i didn't do a very good job of coming into the thread by questioning the legitimacy of how different people define "dirt riding."

for me, i'd still love one of these, or a 950SE. but i also want a KTM 200 for the real gnarly shit, and maybe a trials bike for the even gnarlier shit. and i want my old xr650 back too. and i want a flat-track bike with lights on it. and i want a nice big couch with a fairing too.

but i don't need any of them. not to get to the dirt, nor to ride in it. if you NEED a big adv bike to get to the dirt, then ride the same bike in the dirt, and that is the only bike you need,have or want, more power to you.

Ok, lets take this outside mofo!

Jokes aside, I do agree that my GS is a big ass pig in the dirt. And there is all kinda levels to getting into the shit, there is just no way of riding a lot of dirt and not dumping a big GS. But a lot of us need a way to get too the dirt and as you know a small-ish dirt bike or dual sport does not do that very well. So if your like me and like the dirt but don't have choices. Or if you want to treak down to Brazil then your fukd unless you have a GS or 950 kinda thingy.

Now in saying that there are some people out there with mad freaking skills that can take those big ass bikes anywhere almost so that just throws all this out the door doesn't it.
