We had a question come up in the shop the other day and I was wondering if anyone out there might have some insight.

With the new custom Right Side Drive frames and transmissions, do you still need a Primary offset spacer when using a wide rear tire?  Seems like when you change to a RSD configuration then the motor and tranny could be centered on the frame and there would be no need to offset because the drive is clearing the wide rear tire on the right side of the bike.

my understanding is no you dont but depending on how wide the tire is, i would think you need to have a way of pusing the final drive out and around it, i just assumed a spacer/longer shaft on the right side of the tranny. [smiley=nixweiss.gif]

So instead of a spacer on the left primary, you may have to extend the output shaft of the RSD tranny.  That makes sense.  

I don't think you can just offset the tranny on a RSD frame because you would have a space between the backside of the inner primary and the input / clutch side of the transmission.

I would guess that the manufactures of RSD transmissions have figured this out (to some degree) and accounted for a lengthen output shaft.

Another approach to this is being utilized by Confederate Motorcycle Company.  They are mounting the trans vertically.

How does that work??

I have a lawn mower with a vertical engine!!!!! [smiley=laugh.gif] [smiley=laugh.gif]

Tb, navigate through the site including the press area and you will see that v-twin technology has come a very long way....why if someone were to produce the right volume of them the msrp would fall in line and give the moco a true cvo screamer.
