Power Valve pulleys on the standard bikes can wear quickly and corrode, rusting together affecting operation and potentially causing valve damage. Also, due to the part's design it has a lot of unwanted movement affecting accurate settings. The spring wears itself into the lever and pulley
These pulleys are manufactured from 7075 Aluminium alloy (one of the hardest) and coated in the same tough coating as our racing clutches. The lug is machined larger to help with the load of the spring arm.
The bush is marine stainless steel and highly resistant to corrosion
The 2 items fit snugly together to create a positive engagement with each other, reduce wear and drastically reduce the chances of corrosion for better serviceability and longer life.
TTW does recommend the use of a dry lubricant or smear of grease on the standard spring + regular maintenance and careful set up using the manual.
Weight 88g for 2 pulleys and 2 bushes.
Can be fitted to VJ21/22 and RS250 all years.
IMPORTANT NOTE FOR RS250 - Designed fit only with Suzuki cables. If you have Aprilia branded cables you will also require x4 Suzuki cables available separately
Had these on my bike for a couple of years now, such an improvement everything feels more precise, the free play on the standard items is a joke! These fit better, work better and most importantly look better
