Product Description
JBI Titanium Pro Perch
The next generation of the JBI Pro Perch has arrived. Since the debut of the JBI Pro Perch back in 2013 the Pro Perch has received positive feedback from many riders, tuners, and magazines. Ride JBI always stayed busy learning, designing and developing the next generation of JBI Pro Perch. Building upon 10 years of experience Ride JBI is proud to share the new generation JBI Pro Perch now called the JBI Titanium Pro Perch.
- Improves the bottoming resistance of the fork thus making the fork harder to bottom out
- Provides additional compression resistance (aka bottoming) the last few inches of fork travel
- Allows fork to remain feeling plush, smooth, and comfortable at the top initial starting point of fork travel
- Pressure sensitive damping design provides best mix of fork bottoming control and fork plushness
- The JBI Titanium Pro Perch is able to flex open under high pressure eliminating any high pressure spike
- High pressure spikes aka fast changes in pressure are not comfortable and harsh on the rider
- Designed for twin chamber spring forks
- KYB AOS/SSS 48mm (Production & A Kit)
- Showa Twin Chamber 48mm & 49mm (Production & A-Kit)
- Advantageous for MX, SX/AX, FMX & all types of Off-Road riding and racing
- Recommended oil volumes listed at bottom of the page
- Precision manufactured from the highest grade materials
- Titanium alloy
- 7075 Aluminum alloy
- Low Friction High Density Thermoplastic
- Simple installation replaces the stock spring perch with factory level performance
- Sold as set, sold as pair, 2 pieces
- Patent Pending
- Can be used without or with the JBI Suspension Volume Spacers
- How to install video listed at bottom of the page
What does a spring perch do?
- A spring perch serves two functions inside of a twin chamber / closed cartridge fork
- Primary function is holding the fork spring in place hence the name "spring perch"
- Secondary function is providing additional compression resistance once the spring perch engages the oil in the fork outer chamber.
What is the JBI Titanium Pro Perch?
- The JBI Titanium Pro Perch is a flexible pressure sensitive valve that contributes additional compression damping resistance more efficiently than the stock spring perch for KYB, Showa, and WP twin chamber (closed cartridge) spring forks. For reference comparison the stock spring perch and all other brand spring perches feature fixed holes of various shapes and sizes for the oil to pass through which is referred to as passive damping which is not as effective or efficient when compared to speed/pressure sensitive damping.
Why is it important that the JBI Titanium Pro Perch can flex open instead of being a fixed hole?
- Enabling the JBI Ti Pro Perch to "flex open" when a certain amount of pressure/force is applied is what creates the "pressure sensitive" damping attributes. In this case pressure sensitive is also referred to as "speed sensitive" because the faster the fork compresses the higher the pressure/force will be applied to the JBI Titanium Pro Perch. Pressure/Speed sensitive damping is advantageous because a fork compresses at many different speeds while riding thus allowing the JBI Ti Pro Perch to always provide just the right amount of additional compression resistance. Enabling the JBI Titanium Pro Perch to "flex open" during high pressure prevents the Pro Perch from being too stiff / harsh on the rider but still provide enough resistance to prevent hard bottom outs. The too stiff / harsh feel is common with Supercross spring perches which feature small restrictive fixed holes.
What's new about the JBI Titanium Pro Perch?
- The JBI Titanium Pro Perch is a "complaint mechanism" which now incorporates the flexible bending shims / reed petals as part of the Pro Perch body. This evolution in design reduced the number of parts and complexity from the previously JBI Pro Perch Gen 1 and Gen 2 versions which required mounting the shims and shim retainers to Pro Perch body
Will the JBI Titanium Pro Perch wear out?
- During the 4 years of designing, development, and testing not one single failure happened and is unlikely to happen unless the item is modified or used outside of the above described riding. The JBI Titanium Pro Perch is ready for the hardest of Off-Road, Motocross, Supercross, Arenacross, and FMX riding. Ride JBI uses a high strength and elastic (aka flexible) titanium alloy for the JBI Pro Perch body which incorporates the flexible shims / reed petals. The JBI Titanium Pro Perch was engineered to continuously preform without fatigue in stress conditions that are well beyond the highest stress induced by Supercross / FMX riding.
