Dr. Pulley Slider Weight 18x14 for 125/150cc

Dr. Pulley Slider Weights are a different style of roller

The unique shape of the Dr Pulley weights offer a variety of benefits:

- Sliders engage up to 20% faster than traditional round rollers.
- Due to their form-fitting shape to the interior dimensions of the variator, they allow you to engage in higher gear ratios, even when using lighter than stock weights.
- Dr Pulley Sliders last longer with much less wear than round rollers because they slide rather than roll (hence the name!). Round rollers develop flat spots over time that will contribute to rough accleration and deceleration, as well as reduced overall performance.

Rollers and sliders should be inspected annually (at minimum) for wear. If flat spots or obvious wear is detected, they should be replaced. This is one advantage of sliders, as they already have flat sides and are not affected by this wear as much as rollers.

Choosing the Dr Pulley Slider's weight:

- Lighter weights (7-9g) will give a lot more climbing power at the cost of some top end speed. Cruising speed RPMs will likely increase as well.
- Middle range (10-12g) weights will give improved low end power, climbing, and acceleration versus stock weights. Top speed should be similar to stock weights, and RPMs will be similar to the stock weights
- Heavier weights (13-16g) retain (or slightly improve) existing top speed with the possible expense of climbing ability - but are great for reducing top speed RPMs for better gas mileage.

Buggy Owners: Most popular choices (and why!)

- 9g: For those who want maximum low end power for climbing and acceleration and do not care about top speed. Works best with the stock or yellow main spring. Aftermarket CDI encouraged to allow for more RPMs.
- 10g: For those with a decent amount of hills to climb or want much better low end power without sacrificing significant top speed. Works best with the yellow main spring. Aftermarket CDI a good idea.
- 11g: Great all-around weight for a mix of hills and flat trail riding. Works best with the yellow main spring. Aftermarket CDI worth considering.
- 12g: For mostly flat ground trail riding with occasional hills. Some low end gain, excellet top speed retention. Works best with the yellow or red main spring. Aftermarket CDI worth considering.

Scooter Owners: Most popular choices (and why!)

- 11g: Great all-around weight for a mix of hills and flat road riding. Our most popular weight for scooter owners. Works best with the stock main spring. Aftermarket CDI worth considering.
- 12g: For mostly flat ground riding with occasional hills. Some low end gain, excellet top speed retention. Works best with the stock or yellow main spring. Aftermarket CDI worth considering.
- 13g: Great weight for commuting and those who spend a lot of time at cruising speeds. Slightly better low end compared to stock weights. Possible top speed gain and lowered top speed RPMs. Works best with the stock or yellow main spring. Aftermarket CDI worth considering.

Note: Using Slider weights that are at the lower end of the weight scale can be too light to overcome the main torque spring tension (expecially wih the stronger performance main torque springs) before hitting the RPM limiter in the stock CDI (sparl ignition unit). This can result in less top speed. You can typically get around this using a performance CDI unti with a higher RPM ceiling.
