    Bike feeling "unsettled" after pothole

    So last week i managed to hit a large pothole

    An immediate change was noted to the handling, have checked re checked and triple checked the rims, they are fine

    So have bought new springs for the front forks, and will be rebuilding those in case I managed to finish off the springs

    Any other ideas to what may have happened?

    Bike feels fine at 90 + its lower speeds the bike feels less smooth and more bumpy

    Possibly damaged the tyre. May not be visible though. If the hit was that big and you're concerned about anything, I'd pull the tyres of the rim and inspect inside and out. I'd be less worried about the springs. How big was the hit? Hurt your wrists? Banged your helmet into the screen? Crushed your,,,, yourself hard against the tank? If there are no signs of deformation in the rim, I'd just be checking the tyre closely. Including your rear tyre and go from there.

    Loud enough of a hit that the missus 20 feet ahead heard it

    Suspension bottomed out

    Id be more suspicious of tyres if the bike wasnt still smooth as silk at higher speeds

    Bike is 19 years old and I have no idea if the springs were ever changed on it so it cant hurt

    Ill check tyres soon, its due a back tyre change soon

    Re: Bike feeling "unsettled" after pothole

    Are the tyre pressures ok ? Remember the SBB performs and handles best on 42F and 42R ( Hondas reccomended pressures ) Are the head stock bearings ok ? Just a couple of thoughts.

    Worth checking rear wheel alignment.

    have you tried re-aligning your forks? here's a video. basically, you loosen up the axle pinch bolts and lower triple and bounce the front end.

    i agree with our aussie mate, the springs are probably ok (unless you're a big guy, then they were probably to soft to begin with).

    sounds like something's causing the forks to bind in their travel.

    If you took that hard of a hit I'd also straight edge the fork tubes. They're only 43mm so a very hard hit could tweak them. If it did it would throw off the trail and make to bike unstable.
    Route 191 formerly Route 666 Some say that this section of the
    road has 1100 curves in 95 miles.

    Re: Bike feeling "unsettled" after pothole

    Thank you for all the advice, i will hopefully have the front apart this weekend and check everything is where it should be

    I have noticed the bike feels better when lighter on petrol, so hoping its a simple suspension fix!

    another way to easily check the fork tubes would be to raise the front wheel, loosen the triple clamp pinch bolts and then try to rotate the fork tubes. any binding would indicate they're bent.

    Sorry to pick up on this one, but I found the manufacturer's 42psi settings to be dangerous in the wet - they made the bike feel like it had slippery hard tyres..... 14years (130k kms) running 35psiF and 37psi rear and getting amazing tyre life (eg PR4's.... 20,000kms with tread above the indicators!) and perfect handling (Ohlins fork springs & rear shockie, no need for any steering damper even with forks up 6mm in the clamps) on my 05 SBB .

    The standard Honda springs (front & rear) are too soft, and become uncomfortable..... amazingly, the stronger Ohlins springs are firmer but more comfortable and can carry more weight with ease.

    The guys have covered all the bases on the pothole hit...... I'd put my 20c on tyre damage.... but you may still have to put a gauge on the rim to check for sure no wobbly wheel. Q-did you lose any fork oil? Can you feel any notch in the steering head with the front wheel elevated.... are they loose (forward & backward play?)

    Cheers

    3 spoke rims bend very easily
