Stock Suspension Question


Recommended Posts

How well does the stock suspension handle the things like pot holes, freeway expansion joints, etc.?
 
I'm not looking to modify an FJ-09 for the racetrack or to compete with the YZF-R1 owners out there.  ;)   I use my current bike for commuting and long weekend rides.  The roads are pretty bad in places around Seattle, so I wouldn't want a firmer ride, but a more compliant one that soaks up the bumps.  Does the stock suspension work well in those conditions?

At least for me, at 250lbs, the stock suspension is terrible on anything but very smooth surfaces.  Of course I am not even near the design weight of what Yamaha laughingly refers to as suspension on this bike.  It has the cheapest possible shock with a spring that is likely too stiff for most people.  The forks are a joke... while they have springs in both sides that are way too light for most people, there is damping only in the right fork leg, and it is completely inadequate, and adjustable for rebound only. 
My favorite roads are patches on patches rough twisty roads, and this bike is absolutely frightening on those.  Monday I was on one of those roads and the rear tire was losing contact with the road in bumpy corners and hopping sideways, the whole bike was pogoing up and down.  The front end dives excessively under braking. Couple that with the hair trigger throttle connected to a very powerful and responsive engine, and it was more excitement than I would rather have.
 
Hopefully the money I am spending on suspension (about $1600) and remapping the ECU will make the thing more civilized.  I believe it will, but this is not an inexpensive bike to get into shape.
 
But maybe it works well for 160-180lb riders.  I kinda doubt it.  They say the best you have ridden is the best you know, so if you don't have experience with really good suspension, you might think it's just fine.

300+ lbs here and I'm fine with it. There's certainly better stuff out there but for what this bike is designed for and the price point, I certainly think the "terrible" remarks are a little over the top. If your expectations are high end BMW level comfort and adjustability or ready to push it to the limits at the track you'll be disappointed. If you are expecting budget sport touring, it may even exceed expectations.

It's soft, compliant and mushy. If that is desirable and your handling and tunability expectaions are low you will get used to it. I think it's rubbish for my one up 200 pound experienced riding needs. I really thought it was going to be better, the dive under braking is really extreme.

I weigh 180lbs and ride it hard and think the rear shock is an instant throw away - just complete garbage. The front isn't bad, but the compression is a bit harsh.
I put on a Penske 8983 rear shock and had Traxxion Dynamics AK-20's installed. Very happy with them.

Most people forget that a lot of Jap bikes are designed for an average Asian male, and if you're 5'8" and weigh 120lb the bike is brilliant.
 
I still think the suspension is great for commuting, it's soft enough to absorb BS in the road, but stiff enough to drop low and take a corner.

I'm 145 lbs, 172 with gear. I'm going to get a better shock and have the fork worked on. The fork and shock especially are too harsh on sharp edge bumps once the rebound is adjusted to remove the wallowing effect. It's like there's too much high speed compression damping but not enough low speed.

30 lbs of riding gear? Holy smokes....

28.  I was surprised too.  But that's street clothes, Aerostich, back protector, boots, helmet, gloves.    The suit is not light but I'm not riding without it.
 
Made me understand why when I set the preload with just street clothes on it felt like it was too low.  I would have guessed that stuff weighs 10lbs at most.

Just seems like a lot... I was comparing it to what I used to work  in... The total weight of a firefighter's PPE depends on the tools needed for the job, but basic PPE (helmet, hood, pants, coat, gloves, boots and air pack) weighs about 45 pounds.
