Hello everyone,

I am investigating rear suspension options... based on me (6'3" 300 lbs) and road conditions around me other than interstate (horrible with patches on every seam) I think I could really take advantage of a piggyback. (Logic being I stress suspension and with a reservoir they would get tired so fast)

Question 1: Am I wrong

Question 2: I am not finding a lot of options that can fit piggybacks on R3R, while remote res is a solution it is a pricey one. Anyone other than rob (with a non-standard tail) have piggybacks?

Thanks!

Edit: I am in states so no Maxton
 
*what barb said* Where the reservoir shock is attached to the shock. There are other options that include a remote reservoir that is not actually attached to the shock but is connected via a reservoir line.

From what I have found (and could have completely missed the point):

Remote reservoir == a reservoir that is connected via reservoir line to the shock
Piggyback == reservoir physically attached to the shock. (without a line)

Most places that I can find have problems with R3R fitment with a piggyback and require the (much more expensive) remote reservoir.

It looks like @1olbull made a suggestion where this is not the case. Are you riding a touring or roadster bull?
 
Piggyback's can be a sod to fit if there is not a mass of clearance. It's a major pita with many shaft driven bikes as the spring can foul the bevel housing and so you end up having to mount them the wrong way up. Not a huge issue if the reservoir has a rubber bladder to isolate oil from air. But not many do iirc.

GAZI in Australia does some piggybacks. I don't know if they'll fit without fouling. What is your worry. Heat or cavitation and emulsion? - I am not in your size category. But we have some really ****ty roads. And I doubt I'd benefit much from a remote - though it would provide (generally) more varied damping control )just because there is more space to fit the knobs).

Bear in mind that shaft drive rear ends do need a different dynamic in suspension due to the very different sprung:unsprung weights. The R3's big heavy wheel does not help.
I use Fournales (variable pressurised hydraulics )on the rear as my experience of them on Guzzis was positive.
I have no regrets either except on those odd "brain out" days. Which with age are reducing.
 
I always thought the fouling was done on the fender side not the shaft but that makes sense.

Why not simply kick the piggyback out so that is perpendicular (or at least not parallel) to the bike? Not like they would get in the way up there.

Yeah heat is my main concern, mostly want to prevent the roads from quickly (or if possible, at all) degrading performance. Right now it feels like i don't have shocks if I even get 2 or 3 bumps close enough together. (granted this could also be a downfall of the shocks in snapping back too slowly but these bumps are 10ish ft apart so I don't think so)

Just shopping around most standard shocks (what I'm calling shocks without remote res) go up to 250 at most... so going 20% over that makes me nervous. Or at least it makes me assume i wont get optimal performance out of the shock.

I have contacted GAZI, they can only do a custom remote reservoir solution for R3 which I was told would be significantly more expensive (understandably) than their OTS stuff.

Huh, I hadn't thought about how much more a drive shaft rear end would way but that is a good point. With so much more there no wonder a lot of these places don't have anything for R3.
 

Sorry, I be a Roadster man.
I know the Wilbers fit the Roadster and do not see why not also an R3T. The main frames are the same, no?
