    Once a manufacturer creates the mold, can they easy create the parts in fiberglass as well CF? This may be a good option for parts to be painted.

    My assumption is that the mold can be used for whatever fabric is desired, be it carbon, kevlar, or fiberglass.  There are a couple color options, too (red, orange, and blue), and I'd be checking out the red if I weren't trying to match the C/F on the Tenni.  Here's a pic of the red kevlar weave with C/F.

    I imagine there would be some slight upcharge for colored humps. And maybe glass is less.

    I've seen a used OEM hump on eBay for $200.  Prototyping the mold is going to cost $550.  The more Guzzisti on board now, the more of us there are to share around that initial cost.  If a few more people jump on this wagon, we can get C/F humps for less than $200 a piece.  People who come to the party late will be insulted and subjected to indignities.  :angry::bbblll::angry2:.  This forum has a collective engineering and fabrication tradition to uphold.

    One note:  This part will not include the "rump bumper" -- that is the little vertical pad element.  On the Tenni, the rump bumper is a little different, being covered in the so-called suede (which should, AFAIK, actually be called "rough-out" leather).  The non-Tenni rump bumper is black injection-molded rubber.  I don't know how hard it would be to get rubber rump bumpers made.  I plan to cut something to size and cover it with black marine PU to match the seat, stapled on the back.

    Cheers,

    Dropped some parts off at Riggeals this weekend.  I took him my matte side panel (to match), my gloss hump, and an OEM hump.  

    Here's the quote:

    C/F seat hump:

    Prototyping and mold = $550; each hump = $130.  If 6 of us want humps, we're at ~220.  If we can get a few more folks involved, we can get the price under $200 per item.

    Just in case anyone is interested, C/F side covers:

    Prototyping and mold $710; each unit $110.  I didn't ask, so I don't know if the mold for the other side could be easily (cheaply) fabricated (assuming L and R are symmetrical).

    Possible we could get a discount if there are other parts Guzzisti on the motha of all V11 forums want made in batches (tank chin pad, fenders, etc.)

    We're looking at 3 months for wait and manufacture.  We'd own the molds.

    I'm in on a seat hump if at least 5 others are on board.  If we get that far, I'd need to know weave and finish choices.  Likewise, @docc, may be worth putting out an APB calling all C/F parts wanters.

    Cheers,

    Frey

    Incidentally, I asked Bruno "Brian" Saturno at G-B if he had any interest in making up the humps, too.  He responded that he was happy to continue producing the Trofeo kits and creating a new "evolution" of the Sport Monza kit.  He noted that the carbon belly pans, rear fenders, and wave discs are "always available".

    Cheers,

    Frey.

    I'll come out and say that I'm not a big MM93 fan.  He could use a dressing down like Ice-Man gave Maverick.

    Some arrogance is undoubtedly necessary to do what GP riders do, and deserved for MM, but some of his stunts (both en race and after) have been utterly stupid.  Remember that idiotic arcade game stunt after winning the championship in 2018?  

    I do give MM credit for taking massive bodily injury and getting back in the saddle and piloting a bike again and again.  BBB.  :drink:  Time to retire, or do the VR46 thing?  My guess is as long as he can command $20 million dollars a year in contract and endorsements, he'll stick around until his body quits.  Unlikely that Honda will quit him.

    Anywho ...

    The crash in the Indonesia warm up was spectacular.

    Now, let me understand the dynamics of a high side:

    I found this definition of "highsider" on Wikipedia:

    Technical explanation[edit]

    Forces occurring between the motorcycle and the road (such as those that result in accelerating, decelerating and turning) occur at the contact patch through friction and normal forces. There is a limited amount of force tangential to the road that the contact patch can transmit before the tire begins to lose traction, and therefore slide or skid.

    When going through a curve on a motorcycle, centripetal force (added to the other lateral forces such as acceleration or deceleration) is transferred from the road to the motorcycle through the contact patch, and is directed at a right angle to the path of travel. If the net force is greater than the static friction coefficient of the tire multiplied by the normal force of the motorcycle through the tire, the tire will skid outwards from the direction of the curve.

    Once a tire slips in a curve, it will move outwards under the motorcycle. What happens from there depends on how well the rider is able to restore balance and control. If the tire regains traction after the rider starts to skid while the motorcycle is moving sideways, the tire will stop its sideways movement causing the motorcycle to suddenly jerk into an upright position (and beyond). This movement can easily cause the rider to be thrown off.

    [end quote]

    This makes some sense to my addled brain.  Basically, a high side starts off like a low side.  Then, either: 1) the bike tips further toward the ground, the tire patch evaporates, and the bike skids wheels forward-ish, 2) the lucky rider recovers just enough friction in the tire patch to return to equilibrium, or 3) the tire patch grabs and -- because the axis of the bike has turned too far relative to the direction of travel -- it acts like a fulcrum, turning the bike into a lever and the rider into the payload.

    In option (2) or (3), it seems that at the moment the tire patch grabs, the rear shock would be loaded.  Then, it's a combination of the release of that load and the force (tangential?) from the rotation of the bike (upward/toward the outside of the curve) about the longitudinal axis that can either buck the rider out of the seat or cast the rider into the sky, a la Marquez.

    CMIIW.

    Assuming there's some reason to the above, what are the relative contributions of the unloading of the shock and the rotation of the bike?  How would one modify their shock settings to allow high performance without setting the stage for a high side on accelleration?

    Cheers,

    Frey

    Just spoke to a guy in Gettysburg who's been doing fiber and carbon manufacturing for decades (mostly dragster bodies).  It happens that his shop is directly on a reasonable route for my upcoming trip, so I'll take an OEM hump, a matte carbon bit off the Tenni, and my current damaged carbon hump.  I'll let you know what he quotes and then get a sense of what yinz all would want for options (weave, gloss/matte).

    BTW, read a review of the Triumph Thruxton 1200 R on Motorcycle News today.  In the shootout with the BMW R nine T, the author said, "BMW’s 110bhp flat twin-cylinder R nineT ... Sport version costs £1090 more than the base model and comes with heated grips, a seat hump, a brushed ali tank and high-rise Akrapovic exhaust."  Thus, apparently "hump" is a term of art (also) in the motorcycle community.

    I count six of us replying on this thread (four day old thread with 20 replies and 267 views).

    Seems $300US might be about right for a one-off carbon fiber piece. :huh2:

    What about the price, each, for six?

    That is the price for 6.  I suppose it could come down a bit more for 10...

    Don't have around 1 hour total spare time to invest? That's all it takes in total spread over 2 or 3 events.

    Gotta choose my battles, Phil.  This one, I'd rather pay someone to git er done.  If there's a critical mass of us that want these, maybe we can get the price per unit to a reasonable number.

    If it's prohibitively expensive, then yes, I'll give it a shot.  Or, repair and matte clear, per your suggestion, above.

    Thanks!

    I was thinking @FreyZI was talking about the small cover for the passenger pillion cover (with the "bum-stop"/ "seat cushion" pad attached)?

    Correct -- just the pillion cover.  I have far too little time and comparatively more disposable income to start messing around with this as a DIY job.

    Incidentally, maybe this hump is due for v11lemans.com nomenclature.

    @docc: Yeah, that supposed windshield/flyscreen on ebay is clearly the seat lid.  For a mere $200, you also get the sticker of Manneken Pis.

    Why a Moto Guzzi? moreover, why a V11 anyway? curious? nostalgic? are you odd? just an opportunity? no? what then?

    In honor of St. Patrick's Day, I took out the Green Goose today! :mg:

    Rode into Amish country, avoiding horse puckey on the road, took a mountain (well, what passes for a mountain in central PA) pass (lots of gravel and salt -- I almost walked around the 10mph hairpin switchbacks), and got back into town following a magnificent sunset.  Stupidly, I didn't think to get a pic until too late, but I snapped this image after before it was lost completely:

    20220317_191640.jpg

    Look at that!!!  Where is the "jaw on the floor" emoji?  What a beautiful piece of machine art.  You can walk around these V11 for hours trying to find the best angle to look at them from.

    And riding it is just as special.  I can't make claim to being a great rider, I don't have any idea how to dial-in suspension settings, and I've haven't ridden scores of bikes for comparison purposes.  What I do know is that the grin on the face sets in just after rolling out of the driveway.  Literally.  One moment it's a hooligan; another (around the ton) it's stirring milk tea.

    Pretty great combination, that.

    Cheers,

    Frey

    I'm now a GUZZI owner!

    Now, I need a damned seat cowl!

    So, I "need" a seat cowl, too.  My Tenni came to me very well appointed in CF:  front mudguard, gauges mount, fuel tank chin rest, alternator cover, side panels, hugger, and seat cowl.  The only problem is that every piece of the CF is matte finish EXCEPT the seat cowl, which is high gloss.  This bothers me immensely.  Also bothersome, one of the POs turned the bolts too tight and cracked the cowl a bit; and there's a few other chips in the clear.  I would like to source a matte CF cowl, but I'm guessing that's unobtainium.  How many of us do yinz suppose it would take to make it affordable to get some made up for us?  Seems a pretty easy job (for someone with the knowledge, skills, and tools, that is) -- one small piece, no corners, two holes.  May have to start a new thread on this....

    Thoughts?
