VP3 VP4 fork cartridge valvesProMechA are pleased to release a new series of valves for both fork and shock. Designed in-house, our new system offers the greatest scope for tuning ever. Pictured are our 20mm kits - unique, due to the ability to modify port dimensions to suit the application; allowing a broad range of motorcycle types and riding styles to be accommodated and giving far greater scope for tuning. |

provalve damping control kitProMechA have developed the PROVALVE for conventional forks which offers a full 3 way lo/mid and high speed compression damping with an in-built hydraulic anti-dive circuit. With its integral dive control unit and shimstack adjustable damping control, the Provalve will give your conventional fork set the performance of a cartridge unit. |

The ability to fine-tune suspension is increased enormously allowing for a rider-specific set-up based on weight, riding style and application over and above any standard suspension. Because of the multi-stage shimstack configuration, we can separately control dive rate, lo/mid and hi-speed compression damping. Removing the fork cap and spring allows removal of the Provalve which then can easily be adjusted. | |||||||||||||
|
When fitted with the correct spring and rebound modifications, your conventional fork set will be more than a
challenge for the very best production motorcycle. Promecha Provalves are an Aussie product. The kit comes with an assortment of different size shims and instructions. Easy to deal with, made from billet aluminium and makes a huge difference in handling |

rear shock unitsmodifications to existing units. For the rear shock, a new spring and a revalve will take a lot of the harsh feel out of the shock, and will improve plushness and help control squat. These mods will give you a superior shock when compared to the standard unit.The aftermarket shock will have an advantage, mostly in the way the adjusters work, the piston design and the slippery surface finishes. |

fork springsSprings are the most important part of your suspension. Yet people give surprisingly little attention to matching spring rates to their weight and their riding style; see technical article Springs - the basics |

shock springsIt is important to match spring rates to your weight and riding style ensuring that front and rear rates are complementary, with damping to suit. We supply springs from all leading brands, which are universally manufactured to ISO standards. Contrary to the belief of some, springs do not 'wear out' - it is usually old and over-used damping oil that causes this sensation. |

Below is a brief description of what's involved. Our
quotes are fixed for forks and shocks which are off the bike. Any additional work that may be required will be quoted/advised. |
|||||
fork serviceFully disassemble and clean all parts including shims, valves and adjusters. Refill oil to correct level. Worn seals, bushes, chrome plating are additional. See Maintenance Article for applicable service periods and Damping and Oils for the importance of oil and its usage in suspension performance. |
|||||
fork revalve & serviceFull Service as above. Revalved compression and rebound shimstacks to suit rider style, type of riding, rider feel, rider weight and load carried. Revalving the standard parts matches damping to springs; removing harshness and delivering good results with our individualised setup giving a big improvement over stock. |

fork cylinder/mid valve remove/modifyMany forks have cylinder valves that interfere with compression damping, especially on big hits. Our modification corrects this. Mid-valves also play an important part in compression stroke. Rider preference as to feel and braking control/turn-in need to be tuned to suit the rider. |

provalve damping control kitreb. mod, service and set-upConventional damping systems (damper tube) have many shortcomings, excessive dive, harshness, very poor traction feel. All of these problems can be corrected with our exclusive shimstack driven Provalve high performance damping kit. Because of our multi-stage shimstack configuration, we can separately control dive rate, lo/mid and hi speed compression damping all in one easy to install kit. When fitted with the correct spring and rebound modifications as outlined in our instructions Your conventional fork set will be more than a challenge for the very best Motocross or Enduro bike. For exact fitment details and set-up costs please call. See Hold That Road and Serious Suspension for provalve conversion results. |

fork lowering and servicePrice includes full service as above. Lowering is done internally (front and rear) to maintain handling characteristics. How much a bike can be lowered before handling and safety become an issue is dependent on bike design and application.

shock revalve and serviceWe dismantle and reassemble shock, checking all components for wear or damage and replace and repair parts where necessary. We then revalve according to rider application, riding style and weight.Many shock settings are harsh with limited damping
range. Not enough happens early in the bump cycle to slow and control the bikes progress over dirt surfaces. We modify
your shock to build in smooth, plush feel and give you the ability to control your bike and improve confidence. |

shock service non-rebuildableDismantle and reassemble shock, check all components for wear or damage and replace and/or repair where necessary. Re-oil and re-gas. We convert your shock to fully rebuildable.Over the years we have not yet found a shock that we
can't rebuild. Most modern shocks (let's say from late 80's) are able to be converted into a
re-buildable and fully serviceable shock. Some require machining to have them opened and then we install clips
and regas valve to complete the job. |
