Start with the vehicle at ride height. Droop the wheel ~4” below ride height (measured vertically), record the exact droop. Measure and record the distance between the shock mounts. Raise the wheel to ~4” above ride height (measured vertically), record the exact compression.
How do you measure suspension on a bike?
% Sag = (Stroke Used) / (Total Stroke Length) * (100 %)
The Stroke Used is the amount of suspension stroke used while you are on your bike in a static riding position. The Total Stroke Length is the length of the shock shaft that is available to be compressed. A lot of bikes use different stroke lengths.
How do I choose a suspension spring?
When attempting to determine the correct spring rate for a car, the trick is to
set the ride height so the chassis rests in the shocks’ sweet spot within this small 3- to 4-inch window
. A solid-axle rear suspension, on the other hand, is a bit more forgiving.
Which spring is used in bike suspension system?
The most common type of spring used in motorcycle suspension systems is the
steel coil spring
, which is featured on the vast majority of front forks and rear shock absorbers.
How do you calculate rear suspension?
Cycle the travel through the range and measure the distance from floor to the rear axle at top and bottom positions, then subtract
. So it really is as simple as releasing the tension from the shock and measuring the distance the wheel travels when the shock is fully extended to fully compressed.
What are 3 types of suspension?
There are three basic types of suspension components:
linkages, springs, and shock absorbers
. The linkages are the bars and brackets that support the wheels, springs and shock absorbers.
How do you calculate suspension leverage ratio?
How do you calculate sag on a coil shock?
| Suggested Sag Measurements | Travel 30% Sag | 51mm/ 2.00in 15mm/ 0.60in | 57mm/ 2.25in 17mm/ 0.68in | 63mm/ 2.50in 19mm/ 0.75in |

How do you calculate spring rate on a dirt bike?
How do you calculate coil springs?
To calculate the amount of spring rate you will need on order to meet your working loads, simply
divide the load you will be applying on your spring by the distance you expect your spring to travel or compress under that load
.
How do you measure spring coils?
To test the spring rate, the spring is placed into a spring rate tester, like shown above, and is pre-compressed one inch (or millimeters if you’re using that measurement) and then compressed further to get the measurement for the next inch of compression.
What is spring rate formula?
| Solid Height | Solid Height = (Number of Coils – 0.25) x Wire Diameter | Rate = Load (lbs.) ÷ Spring Deflection (in.) | For example, if a spring deflects by 2.75” under a load of 300 lbs, the Rate would be calculated as follows: | Rate = 300 ÷ 2.75 = 109 |

How do you measure a rear shock on a mountain bike?
How many types of bike suspension are there?
There are
two types
of motorcycle rear suspensions, one is Single Suspension (Mono Shock) and the other one is Double Suspension (Dual Shock). There are also custom-built rear shock absorbers out in the market which are built as per the specifications of the bike, riding style and weight of the bike.
Which type of suspension is best for bike?
A motorcycle suspension setup primarily consists of two telescopic tubes at the front and a swingarm mounted with twin or single shock absorber at the rear. Now a days,
monoshock or single shock absorber at the rear
is preferred in most of the bikes because of its better performance and sporty looking characteristics.
How do you calculate wheel travel?
Since the circumference is equal to πx D, it is equal to:
3.14 x 3.125′′ = 9.81′′
. With the wheel turning 9.81′′ in one revolution, it would travel: 9.81′′ x 3.625 revolutions or 35.56′′ total.
How do you measure front suspension?
If you are trying to measure total travel you will have to let the air out to easily cycle the fork through the entire range of motion.
Use a zip tie around the stanchion to make the measurement. Push the zip tie down to the wiper seal and then compress the fork all the way
. This is your total travel.
How is rear wheel travel calculated?
Mount the bike on a bike stand(if you have one), remove the shock, cycle the rear arm and measure
. Presto, there’s your travel.
What are the 5 types of suspension spring?
- 1.1 Semi-elliptical Springs. …
- 1.2 Quarter-elliptical Spring. …
- 1.3 Three quarter elliptical Spring. …
- 1.4 Transverse Spring. …
- 1.5 Full-elliptical Spring.
What are the 4 components of suspension system?
- Tires. These are the only part of the suspension system that touches the ground.
- Coil springs. These are the part that absorbs the impact when a vehicle hits a bump in the road.
- Shock absorbers. …
- Rods/linkages. …
- Joints/bearings/bushings.
How do I build my own suspension?
What is leverage ratio formula?
This leverage ratio attempts to highlight cash flow relative to interest owed on long-term liabilities. To calculate this ratio,
find the company’s earnings before interest and taxes (EBIT), then divide by the interest expense of long-term debts
.
What is suspension leverage ratio?
The leverage ratio is
the ratio between the distance the rear wheel moves vs. the distance the shock moves as the suspension cycles
. The average leverage ratio is therefore the ratio of rear wheel travel to the stroke of the shock.
What is a leverage ratio calculator?
We have prepared this financial leverage ratio calculator for you to quickly estimate the financial leverage ratio.
It tells you how much of the company’s assets are financed using debt instead of equity
. This ratio indicates the amount of leverage risk contained within an entity.
