With the exception of scooters and shaft drives, most motorcycles, from mopeds to mega-sports, transfer drive power from the engine to the drive chain (henceforth "chain").
It is known that chains need to be lubricated with chain oil, but it is equally important to check and adjust the chain tension and deflection.
Chain deflection also affects suspension movement.!?
The drive chain is the most popular power transmission method for any model year, displacement, on-road or off-road vehicle.
A variety of chains are used, from the 420 size, which is common on mopeds, to the 530 for larger vehicles.
To make your motorcycle chain last longer, you need toRegular cleaning and lubrication is essentialBut there's one more thing that's important."The right amount of deflection.That's what I mean.
in this contextDeflection.TheBefore and afterMiddle of the sprocket.And the chain.The amount of movement when moving up and downrefers to.
Why is the deflection of the chain, of which we are rarely aware on bicycles, necessary on bikes?
One of the main reasons for this is thatThe presence of rear suspensionIt is.
The bike chain moves up and down around the swing arm pivot.rear tireThe driven sprocket assembled therein (rear sprocket) and a drive sprocket mounted on the engine (front sprocket) connected to each other.
If the pivot shaft and drive sprockets are centered in the same position, the chain deflection will not increase or decrease as the distance between the front and rear sprockets remains constant when the rear suspension moves and the rear tire moves up or down.
It's like a bicycle without an external transmission.
However, the drive sprockets on most bikes are mounted before the pivot shaft, soWhen the rear suspension moves and the tires move up and down, the driven sprocket andMisalignment of the chain's trajectoryarise.
The proper amount of deflection in the chain is thisAbsorbing misalignmentExists to doI do.
Chain maintenance includes cleaning and lubricating, andDeflection is the key.
The track of the chain can be displaced by the vertical movement of the tire.

It is important that the rear suspension remains flexible when it shrinks.
As the mileage of the bike increases, chain sagging generally increases.
Pick the chain at the bottom of the swing arm and shake it.Dull up and down.The move toThe deflection is too great.Signature.
How much deflection is appropriate is described in the instruction manual for each modelSome motorcycle manufacturers make this information available on their websites.
So, if you don't have such information, what level of deflection is appropriate to adjust to?
Sometimes with bolts and screws, you feel like you have to "tighten up" to keep them from coming loose.
In the same way, you might think, "It looks better to be taut than loose,Don't over-tension the chain.It is.
The difference in distance between the front and rear sprockets and the distance between the swing arm pivot and the driven sprockets changes the amount of chain deflection depending on the amount of suspension shrinkage, and therefore the position of the rear tire, which is a feature of motorcycle chains.
And as the suspension shrinks, depending on the rider's weight and riding conditions, the deflection of the chain decreases.
in shortWhat is the proper amount of deflection?Suspension in full bottom condition.But still, the chain doesn't stick out.The deflection is still there.be (a person)You can say.
If you have the sense that "it looks better to be taut than loose,When you reduce the amount of slack in an empty carAs the sass shrinks, the tension of the chain becomes stronger.
When there was zero slack between the front and rear sprockets, and yet there was still room for shrinkage in the suspension, the chain was subjected to excessive pulling forces andCauses of "uneven elongation" where one part is stretchedor by applying a large force to the drive sprocket.The cause of the load on the engine itselfThis is the case.
Excessive deflection can cause the chain to jump over the sprocket teeth or come off the sprocket teeth, and there is also the risk of the chain making contact with the swing arm during acceleration and deceleration, so too much slack is not a safe bet.
It is important to set these values within the standard values set for each model.
