cush drive do or don't...

About a year or so ago I destroyed my kite (non cush drive) hub because sprocket bolts came loose.
I temporarily fixed it by drilling the oval 8mm holes to almost 10 and threaded the holes now I can still use the hub.
Downside is I also have to adjust al rear sprockets to make it fit and changing a rear sprocket is a lot of work (use longer bolts with locktite and nylon locknuts on the back of the hub and first have the adjusted rear spr).

Now there are a few options when my chainkit needs to be replaced:
-drill all holes to 10mm and get some spacers machined with outer diameter 10 inner 8 that fit perfectly flush in the hub this way I can use stock sprockets/bolts without any adjusting.
-Keep using the method I am using now and adjust the rear sprockets (cheapest option but don't like it)
-Buy new hub prefer a cush drive because on my rebuild gears where damaged maybe this was just because of the incident of the bolts that came loose but maybe not.

The bike has over 60 hp on the wheel so it puts some stress on the drive shaft/hub I think for durability cush drive would be better but I mailed some company's who sell hubs and they can't even replace it on my wheel because it's a tubeless system that needs different spokes so I probably would have to send my rear wheel+new hub to alpina to get it done...

Most aftermarket wheel company's don't even offer rear wheel with cush drive because it would not be necessary on mx/supermoto
(but my bike puts out +10hp compared to average supermoto bike and it's possible I want even more power in future )

I have a steel rear sprocket on now to but I only change between front sprocket for the moment currently running 14/43 15/43 for tracks with topspeeds around 180
For me wear on sprockets and chain is not my biggest concern its the expensive main drive shaft and gears in there I replaced gears worth approx 500 euro last rebuild.
My first time replacing the chain kit I looked at what was lightest and lowest roll resistent.
But powerfull supermoto eats chaind so now I choose durability even if its almost an extra kg of weight chain is rated for +1000 cc bikes and over 200hp so it lasts much longer

The stock wheel has a cush drive but I sold them I bought alpina carbon tubeless wheels the price difference compared to the tubeless wheels from husaberg with a 5inchy rear was small so I chose for extra bling lower weight and better tubeless system only downside no more cushdrive.

Very Interesting stuff

I already contacted haan to see if they can instal a cush hub on my wheel but they say they cant because the alpina have specieal type of spokes maybe if I contact alpina they can install a cush hub on request but I would already lose 100€ on shipping costs back/forth only than cush hub/labour it would not be cheap for sure....

I asked alpina what they could do for me now just wait for reply yes brugge is a small town with a lot of historcal **** some american tourists think it's a theme park or something

Alpina got back to me and they are saying I can send my wheels together with hub (alpina themselves can't supply cush hub for the 570) to italy and they will rebuild them.

(will send both front/back for rebuild because the front has been losing air quiclky recently... )

Cost would be 240€ excluding the cost of the hub and excluding the shipping cost I have to pay to get them in italy... (140 rebuild/100 shipping)

Alpina said talon has a cush hub for my bike but If I google talon cush hubs I read some people have issues wit them so I would probalby buy a OEM cush
hub from hsb/ktm (cost 262€) and send it alll together +-600€ to get my wheels back good like new and with cush hub.

Only downside the rear hub will be boring/ugly grey instead of bling bling annodised blue but for me performance/reliability is first priority

Not sure if I will send them now or wait till after my last supermoto trackday this winter in march depending how big my end of the year bonus will be

Looks nice but would cost me another extra 300...
And dont know these someone any experience with those for that money they better be realy good...

Shipping a rim to italy is expensive from belgium shipping to us would be crazy I guess but I could Just buy the hub get it shipped to me and than send the stuff to alpina to get it rebuild.

I have some time to think about it will ride only one more time im march with my current hub.
(after that new chainkit is coming on and I will ride my racebike in May.

So will have some time to get the berg in perfect condition while riding my other bike.
