Laverda Wheel Drum Set Up Spoke Size

Hum! - Depth of Nipple with Aftermarket Rims - No experience with After market Rims but potent point. I can see if the Depth is not sufficient to bury the nut of the Spoke Lock Nut, due to the exaggerated angle of the SF Hub, could easily puncture the inner tube, which all Spoke Rims must use. I use a die grinder and smooth the Nut Flange and ensure the Teflon Belt is properly seated before installing the Tire and Tube.

No Cycle Shop will do this today as they have no comprehensive thought, considering they charge you over a $100 just to change a Tire - So you have to do it yourself and learn how to mount your own tires if running SF Hubs.

I gotta say the Cabled Servo SF Super Ferini Hub is Adi-quite & Dependable as you have over 8x's the Pad area of a Hi-Pressue Hydraulic Disc. I'm still running the Original Shoes after 45 Years. Stopping power is nothing more then a Sensual Squeeze of One Finger and light toe pressure & Superior over Non-Sensual Disc's in the Rain. The SF Brake is vary capable of hauling you down from Hi-Speed through numerous corners but probably will tend to fade over Extreme Conditions which I've yet to encounter.

I've been holding onto nothing more then handle Bars to prevent me from catapulting over the Bike under extreme Stops - The Cabled SF Brake has not only save one particular Pedestrians life but mine, many times over.

Buc,

No way you are going to get a rim meant for a small diameter hub like that of a XS650 to fit a large hub like the Laverda.  The bore angle is way off, as is the position in the dimple.  The hub and rim will never line up.  Can't hink of any modern time rim that would suit the Lav hub, or even comes close, probably be easiest/cheapest to have a blank rim drilled by your favourite wheelbuilder.

Cam,

I have seen examples of pulled spokes on both Borrani and Akront rims.  I know of the Akront that the owner was a right prick, no maintnenance and always a WOT.  Wheel wasn't the only thing he fucked...

Also lots of examples of broken spokes, mainly stainless but a couple of thick steel buggers in the rear wheel thrown in for good measure.  A real pita to replace if it's an inner spoke.

Have also found quite a few cracked hubs through over-tightened spokes.

I know of one which has been laced to a 19" rim, it was a takasago rim similair to the ones used on the xs650's front.

I also have a xs650 rear alloy rim which is laced to the xs650 standard rear drum, it's a 18" rim, I was thinking if anything is going to come close to angle required it's going to be this rim. So I would run that on the front. What do you guys think? Any recomendations?

With the akront rims, what am I looking for which will tell me it's the right rim?

Cheers
 
Unless you can source ready replacements for the Lav wheel, get someone to drill the rims for you and do the spokes and build it. Any decent wheel builder will be able to sort it out for you. Any good quality 36 hole rim will be ok but the drilling will need to be very accurate to place the nipple correctly, the angle is not extreme but just more acute than for a smaller hub and I doubt you will find an off the shelf generic pre-drilled rim. With respect it sounds like you are a bit out of your depth on this and could just end up wasting time and money trying to mix and match.

Yes you are right this is out of my depth as I have never built motorcycle wheels before, that is an option on getting a rim drilled to the required specification, I am just trying to find out if anyone has done it differently, as I said, I have seen the drum laced up to a 19" takasago rim.

Will be taking my drum to a wheel builder and see what he says.

 
This guy has been runing xs650 front rim on it for years, he races the bike alot also

Not at all mate, hence why my dilema with this 18" option. This is the look im going for

Buc, before deciding on what wheel size you want to go with keep in mind the future availability of whichever tires you prefer. I've noticed over the last two years fewer manufacturers are producing the "oddball" sizes now. 18s are much more common than 19s so we should have a good choice of black donuts for the foreseable future. This doesn't mean the 19s won't be produced at all but that your selection will be severely limited.
