My Bike is "Rocking" me...
Posted: Wed Sep 16, 2015 3:30 am
Hello,
I have an issue with my Forza 2014.
When driving at even speed (just giving enough gas to maintain the speed) between 35kmh - ~80kmh, and when slowing down from ¨100kmh and engine-breaking, there is a firm but very obvious “rocking” behavior (not jumping) on the bike. I feel that the whole bike is moving up and down about 1cm so to say. The frequency of this ‘rocking’ is perhaps about 3-4 Hz at 35kmh, and increases all the way up to around 80kmh, then it kind of disappears. If that is due to the ‘rocking’ frequency gets so high when the speed increases or what I cannot really say, what I can say is that it’s not at all as significant during higher speeds. and really not below 30kmh either.
I am not that an experienced scooter driver, but this behavior was definitely NOT on the PCX125 I had, so it doesn’t seem like a ‘feature’ for Honda scooters.
Does anyone recognize this or have any suggestions to why this could appear? else than too hard/soft suspension, too high/low air pressure in the tires, cause those I have already tried to change with no change at all. I am completely lost in this, but my thinking is that It definitely has something to do with something revolving, either the wheels are not circular? or something in the transmission/engine/belt-drive is off-axis? Could something like that make this behavior?
I actually had it on service for the fuel-pump exchange and the shop took a look at this problem also, but as usual, they couldn’t really say anything and just checked the obvious things and took a short test-drive (not when I was present of course) and just… - “well, I couldn’t fell any problems”. Duh! Why does it always feel like they really don’t listen?
Anyway, I would really appreciate any advices, just to give a hint to Honda when I have to try and explain this again and make them take this on seriously…I mean, the bike is almost brand new, I have ran it only for 1800km and to be honest, I have felt this almost from the very first time I drove it out of the shop.
BR, Thomas
