Has anyone fitted 20mm shorter Nitro shocks on a Rocket. In theory it should lower the seat about 25mm, just wonder if there is anyone with experience of this.

11.5" Progressives would lower the seat by nearly 40mm, not sure that isn't too much for suspension/tyre clearance.
 
Yes I have the Hagon Nitros on the back of mine (1" shorter).
I can have both feet flat on the ground.
BUT... everything is Then closer to the ground (bottom of the engine and foot pegs.
I also have tge BS exedra max which raises the bike a time little.
I have noticed that with the bike lower plus the larger diameter tyre, the tyre can rub on the under side of the guard.

I used 12" 440s
Now have 11.1/2" 418s
No clearance problems
Doesn't squat so much when piling the power on
but I don't push it on the corners
 

When you say 1" shorter do you mean 1" lower? The reason I ask is because when I spoke to Hagon yesterday they said that they only change the length by 10mm units. Standard length is 320mm and 300mm would lower the rear end by 1" due to the geometry of the mounting points.

If my calcs are correct you have lowered by 1" with shocks and raised 1/2" with tyre so have a net lowering of 1/2", does that seem about right?

So in theory you have lowered by about 40mm without any problems? that's interesting. Need to ask if you ride with passenger and luggage. Also what tyre you running?
 

Hi Colin,
I just measured to distance between the posts 290mm, so I assume that in 10mm shorter than standard - 1" lower. Like I said - I do scrape the tyre but I have not wound up the stiffness at all, This is something I plan to play with....
Hope that helps

I have Hagon Nitros on my touring. Talked ro their rep, gave my weight, how I ride, and that I wanted ro lower the bike. They rold me exatly what I needed. I changed the front springs also, a smart thing to do. Now my veet are flat on the ground and the bike handles great. I still have the box in the garage if you need ghe particulars.
 
Colin - As pressured air is not a mystery to you. Think about Fournales as well. But buy direct from Fournales if you do.

Mine are on spec over length - but air shocks need to be longer ime.
