Rise the bike 5cm

When I rebuild the front fork with new part the total height went up approx. 5 cm... when I received the Hagon rear suspension today, they was also approx 5 cm longer.
So my bike will be 5cm higher in front and rear then before, what effect will these has on the handling?

When the engine is installed and there is gas in the tank the height will drop a 2-3 cm.

When I measure the actual length between old and new rear suspension the new Hagon is 4cm longer.

New or rebuilt suspension needs to break-in.

4 cm longer is a lot. Why did you purchase shocks that were that long?

On my 750 the swingarm would hit the stock mufflers unless the shocks were kept to within about 1.5cm of the stock length.

Gordone;
If you keep the longer shocks then when you check and adjust the chain make sure you do this with the rear wheel on the ground and not with bike on the centre stand otherwise the drive chain can end up to tight.

I agree that you're gonna need to put the WHOLE bike together, 'cause there's a "SAG" factor wherein the bike's own static mass will compress the suspension, and the rider will compress it further. If you're talking about a half-built machine, that'd explain everything.

BUT IF NOT, if you're only talking about work done on the suspension alone, and your bike already IS fully assembled? Well then I'd wonder whether your OEM springs and shocks were cut down by a previous owner. You're sure they're OEM shocks and not a stock-STYLE of "Shorty" shock set? And the original springs well, I could definitely see 'em wearing out and sagging further. Maybe the rear shocks as well!

I guess you'd want to look at the specs from the manual, accounting for all of the other factors you've changed such as tire aspect ratio etc, and look at the seat height of the completed bike. IF you're doing a bone-stock restoration, this would be a lot easier than if you've changed a whole bunch of stuff.

But yeah, I'd suspect the P.O. might have dropped in springs from another model, shorty shocks etc - OR they could be worn out.

UNLESS of course, the seller you bought 'em from made a mistake - in BOTH instances though? If you measure the original springs, perhaps the sellers could help clear up whether those original fork springs were intended for your bike in the first place.


-Sigh.
