The answer is simply because
the front fork height greatly affects how the dirt bike controls
. It is also an easy way to tune out some unwanted feedback and instability in higher speeds. Factory dirt bikes are usually set to the middle position and most riders never touch the fork height.
What does raising the forks in the triple clamps do?
Raising the fork tubes in the triple clamp is a simple adjustment that can
help make a motorcycle respond faster to steering input and can lower the motorcycle
.
How do you adjust the height of a fork?
What is the purpose of bike forks?
A bicycle fork is the part of a bicycle that
holds the front wheel
. A fork typically consists of two blades which are joined at the top by a fork crown.
How can I make my bike forks longer?
How does fork length affect head angle?
As the fork gets longer, it raises handlebars up and slackens the head tube angle
. As a rough estimate, each 20mm of travel added will correlate to a one-degree difference in the head tube angle.
How do I make my front forks longer?
What happens when you lower the front end of a motorcycle?
By lowering the front end, you are
manipulating the bike’s rake and trail settings
. Without getting too technical, this will make your bike quicker turning at the expense of reducing high-speed stability. If you stay conservative, you may not notice any handling differences.
How do you adjust a triple clamp?
Where do you measure fork height?
Fork tube height is measured
from the top of the fork tube down
. It does NOT include the fork cap. For example, raising the forks 5 mm in the clamps means that there is 5mm of the fork tube sticking out of the top triple clamp.
How do you adjust the fork height on a dirt bike?
How do you adjust forks on a dirt bike?
To adjust your sag, you will need a hammer and punch, or a specialty tool offered by the manufacturer.
After you loosen the shock spring lockring, turn the spring preload ring to increase or decrease sag
. A general rule of thumb is that one complete turn changes the sag by about 3mm.
Are air forks better than coil?
Air forks provide better bottom-out resistance
Near the end of the range, it takes a huge amount of force to further compress the air inside. The total amount of force required to compress an air fork and bottom it out is greater than a coil fork. This is assuming that both are set for the same rider weight.
Do air forks have oil?
Rather than do what’s required with conventional forks (that is, bottom the fork out and then carefully measure oil heights), all you need to know with the AER is that
there’s 200ml of oil in each leg
. Pus the oil contained within the WP air fork’s outer chamber is purely for lubrication.
When should I lock my front fork?
Usually the only times you would lock out your rear shock (or front fork) would be
when on a long non-technical climb, or other long distance ride
. Mountain bike suspension often features multiple modes, to better set up the bike to climb or descend, and one of these common features is the lock out.
Can you put a 130mm fork on a 100mm bike?
at 130mm you’ll probably be fine, I wouldn’t put anything bigger on there
. The kona frames are pretty strong, I used to run a 130mm fork on my 100mm jump bike for AM and a lottle more FR riding, I was fine.
Can I put a 120mm fork on a 80mm bike?
120mm would be long for an XC frame that came with an 80mm fork.
I doubt the manufacturer would recommend this
, however lot’s of people do those kinds of swaps without significant issues. It is pushing the design limits of the frame, and if you’re pushing the limits of what the bike can do, you may run into problems.
Can you put a 130mm fork on a 120mm bike?
Nope. It will be fine and will take more than 10mm to make an appreciable change
. You might notice the handling difference, but it will be slight and won’t negatively affect anything.
How does fork length affect trail?
Lesser fork offset will result in increased trail
. In your case, going from a 45cm to a 43cm offset will increase trail by probably less than ~1mm.
How does fork rake affect bicycle handling?
Fork rake is only part of the steering story, as
a greater fork rake will increase the wheelbase
, which is prevalent on endurance bikes to create stability. The below image shows an example of how an increase in fork offset or rake which reduces the amount of trail and as a consequence speeds up the bike’s handling.
Is more fork travel better?
The more travel a fork has, the bigger, heavier and stiffer the fork will be
, so the chassis will be designed to reflect these demands too. The payoff for having a burlier fork chassis that’s more capable on the descents is that it will feel big and cumbersome on the climbs.
Can I put a 160mm fork on a 150mm bike?
A 160mm will probably slacken the bike a bit and make for a more stable DH experience at the expensive of climbing ability
. Running up to 180mm on a bike designed around 150mm will probably be too much, and make the overall handling poor and undesirable.
Can I put a 120mm fork on a 100mm bike?
For all around riding,
should be fine
, but you may notice it’s a bit harder to keep the front wheel down on the steep uphills.
Can I put a 140mm fork on a 100mm bike?
There is no good reason to slap 140mm fork on a frame that is designed for 100
. It will no ride better and it may break, like many other already noted.
Does lowering a bike affect handling?
Effects on Handling
Even if you lower your bike by the book,
handling can be affected to some degree
. “When you lower a bike, you also lower its center of gravity, so it’ll handle a bit better in certain circumstances,” says Langley. “The negative is that your initial ground clearance is decreased.
Is it bad to lower your motorcycle?
Motorcycle experts will always advise against lowering the front of your bike for both safety and functionality
. You can get away with lowering only the back if you’re going for function, but for appearance, many of you will want to lower the front to match it.
Is it harder to wheelie a lowered bike?
lowering will make it harder to wheelie
, just give more gas. it always takes alot more gas to do what you want. just don’t wrap your hand around the back side of the throttle.
