What does KTM PDS stand for?

What does KTM PDS stand for?

Progressive Damping System

It was the first KTM to use the Progressive Damping System (PDS) and had no linkage, only a solid mount between the swingarm and the Ohlins shock. Within the shock there was a needle that would engage a twin-piston design, progressively increasing damping through the stroke of the shock.

How does KTM PDS work?

The PDS System uses two pistons in an attempt to make more compression damping as it gets closer to bottoming. They feed the oil to the Primary piston through a hollow damping rod.

What spring rate do I need for my dirt bike?

Right out of the box your spring rates are usually set for someone of average size — this typically means 75 to 80 kilos or 165 to 176 pounds. If you are lighter or heavier, that spring rate won’t perform as well for you. Next, determine your static sag and laden sag.

What is the difference between KTM and Husqvarna?

The most notable difference with Husqvarna models is the use of a carbon composite subframe. Photo by Kiska. Husqvarna models also use Renthal handlebars whereas KTM and GasGas models use Neken bars. There are also some variations to the fuel tank designs across brands.

Does spring preload affect stiffness?

It’s important to point out that preload doesn’t affect spring stiffness. You can compensate for a too-soft or too-stiff spring by using preload, but you’re better off changing the spring itself.

What shock spring do I need?

For example, if your shock stroke is 2″, your max spring free length is 130mm and your spring rate is 450lbs, you need a spring that is 2.25″ x 450Lbs x 125mm (if you don’t see a spring that has the exact stroke of your shock you can use a spring with a longer stroke, as long as the free length will fit).

Why KTM is better than Husqvarna?

The biggest difference among the 350s is power. The KTM is more aggressive, snappier and it seems to genuinely be faster. It’s not appropriate to call either bike “hard-hitting.” They both have incredibly smooth power deliveries and very wide powerbands. The trick to riding either one is to stay on it.

Is GasGas made by KTM?

Gas Gas is a Spanish motorcycle manufacturer established in 1985 by Narcìs Casas and Josep Pibernat in Salt, Girona. The company specializes in off-road motorcycles for trials and enduro competitions. Gas Gas was purchased by KTM motorcycles in 2019.

When did KTM buy WP?

In 1999, KTM acquired WP, but it wasn’t until a decade later that manufacturing was moved to a huge new factory in Munderfing, Austria, a few kilometers from KTM headquarters in Mattighofen. (The original WP facility in the Netherlands is now used solely for race support.)

What does too much preload feel like?

Too much preload (Rear)
Damping is overwhelmed. Feels harsh and bounces back hard after contacting bumps.

What happens with too much preload?

Can You Have Too Much Preload? Springs work in both extension and compression so too much preload makes the springs too soft on compression. When this happens we have to compensate with shock valving and sometimes that can lead to harshness.

How do you choose shock spring rate?

Use A Spring Rate Calculator
Simply input your riding body weight, your shocks stroke, your bike’s rear-wheel travel, and choose if you’d like a more plush ride with about 33% sag or a more supportive ride with about 28% sag.

How do you calculate spring rate?

The unit of measurements of spring rate is N/m or Ibf/in i.e. force divided by distance. The spring rate of a spring is the change in the force applied divided by the change in diversion of the spring.

Is Husqvarna owned by KTM?

Why is WP suspension called white power?

Peters founds WP – and gives the success story a name. This is entirely in line with the uncompromising focus on technology. “White Power” Suspension – not a political statement, but an allusion to the striking white springs used for his products.

Does preloading a spring make it stiffer?

Does preload affect ride quality?

Preloading is not the same as using a stiffer (higher spring rate) spring. Preloading does not change spring rate but preload does change the force to start moving the shock and high preload dramatically reduces shock performance over smaller bumps and makes for a more harsh ride and worse traction.

Is higher spring rate better?

Although a higher spring rate reduces body roll, it comes at the expense of a harsher ride. “Not only will a softer spring improve ride quality, it will also enable the tires to follow uneven road surfaces more precisely for improved grip.

What is a good spring rate?

Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle.

What spring rates do race cars use?

 0.5 – 1.5 Hz for passenger cars.  1.5 – 2.0 Hz for sedan racecars and moderate downforce formula cars.  3.0 – 5.0+ Hz for high downforce racecars.

Why did BMW sell Husqvarna?
