1 (ONE) Argentine Lignum vitae (ALV) flat grain knee slider SUPER HARD

Lignum Vitae, translates from latin as "wood of life". ALV and all other trees in the genus guaiacum are considered to be some of the hardest woods in the world. ALV has a Janka scale rating of 4,200! Ipe is rated at 3,680, and white oak is 1,360. The incredible density as well as the waxy nature of ALV makes them Puck-Em's longest lasting sliders. ALV flat grain wears slightly faster than ALV end grain, the difference is noticeable. The advantage of the flat grain is how it can take a beating against curbing and never chip. I recommend these for riders who really abuse their sliders and bang into curbing frequently. The attached photos show how smooth and evenly the flat grain ALV wears.

Maximizing the performance of a motorcycle on or off the track requires investing time, effort and money into tuning frame geometry and suspension, tire temperature and pressure, as well as devoting attention to reading tire wear and of course spending countless hours developing riding skills. Tuning your sliders to performance their very best takes tuning as well. Positioning your Puck-Em knee sliders correctly is essential to maximizing their longevity and getting the best feel. The entire face of the slider must be in contact with the ground, not just an edge or corner. Put your new sliders on and touch both sides to the ground once or twice. Reposition both sliders so that the plane of contact matches the main surface of the top of the slider. This will take moving the slider in and out as well as up and down to get the planes to match. If you are at the track, don't wait to reposition after 1 whole session or you will never be able to achieve touching the entire face on the ground until most of the slider is worn down. Once you have gotten the positioning exactly right, consider marking the loop on your knee around the slider so that you will easily get the next set in the perfect spot. This can be done with a colored pencil, crayon, paint marker, or tape.

Sometimes leather suits don't have enough loop fastener on the knee to get the correct positioning. In this case you can add additional loop where you need it. Please contact me directly if you need help with how to do this. Essentially, all you need to do is thoroughly roughen the smooth side of the leather (with a Dremel or sand paper), and a high quality contact cement like Barge. I'd be happy to mail you enough high quality loop fastener for both knees for free (if you have purchased Puck-Em sliders).

1 (ONE) Argentine Lignum vitae (ALV) end grain knee slider SUPER HARD

Lignum Vitae, translates from latin as "wood of life". ALV and all other trees in the genus guaiacum are considered to be some of the hardest woods in the world. ALV has a Janka scale rating of 4,200! Ipe is rated at 3,680, and white oak is 1,360. Their incredible density as well as the waxy nature of wood makes them Puck-Em's longest lasting sliders. End grain is more wear resistant and wears a bit slower than flat grain. The only disadvantage of end grain sliders is that it tends to chip around the edges when they bang into curbing. If you lift your leg when passing over curbing then chipping should not be an issue at all. If you know you do bang into curbing yet want the longest lasting slider possible then the flat grain ALV may be a better choice for you than end grain.

(1) ONE Ipe END GRAIN knee slider HARD (1) ONE Ipe END GRAIN knee slider HARD

(1) ONE Ipe flat grain knee slider HARD

Ipe (pronounced ee-pay) wood is 3 times harder than white oak and has a Janka hardness scale of 3,680 while white oak is 1,300. The main face of the slider is end grain and, as a result, it's wears a lot slower and lasts much longer than flat grain ipe. (Note: This is not the case for the end and flat grain lignum vitae which wear at a much more similar rate.) The only disadvantage of end grain of any type of wood is that it tends to chip around the edges when it bangs into curbing. If you lift your leg when passing over curbing then chipping should not be an issue at all. Ipe end grain sliders are intended for riders who prefer a larger size yet still want a very long lasting puck. Flat grain ipe sliders would be a good choice for someone who only goes through several sets of sliders per season. The higher cost of end grain ipe versus flat grain ipe is a result of needing to cut the pucks from 4x4 posts rather than much less expensive 4/4 decking. The natural color of the wood varies from deep red to chocolate brown to nearly black.

Ipe (pronounced ee-pay) wood is 3 times harder than white oak and has a Janka hardness scale of 3,680 while white oak is 1,300. The main face of the slider is flat grain so it wears a little faster than the end grain but resists edge chipping much better than end grain. The flat grain also contributes to the lower cost. If you bang into curbing a lot I recommend flat grain over end grain sliders. Ipe flat grain sliders are intended for riders who are relatively easy on their pucks. The less expensive ipe flat grain would be a good choice for someone who only goes through several sets of sliders per season. Riders who are heavy knee sliders will be disappointed by the fast wear rate of flat grain ipe.

(1) White oak knee FLAT GRAIN slider SOFT/Ultra Light Weight (1) White oak knee FLAT GRAIN slider SOFT/Ultra Light Weight

(1) ONE white oak flat grain knee slider SOFT

White oak has a Janka hardness rating of 1,300. They are much softer than the other other wood species I offer; ipe is 3,680 and lignum vitae is 4,000+. They are intended for racers who prioritize weight savings. They are extremely light at around 4 onces each but what you gain in weight savings you lose in durability. They wear down rather quickly and don't last long. If you are a heavy knee slider expect these to last 2 or 3 races at the most. I would also recommend them to riders who rarely use their knee sliders and go through no more than 1 set per season.

They are intended for racers who prioritize weight savings. They are extremely light, but what you gain in weight savings you lose in durability. Even the standard rain thickness wears down quickly and don't last long. I would also recommend them to riders who rarely use their knee sliders and go through no more than 1 set per season.

06-16 YZF-R6 Captive Caliper Bracket 06-16 YZF-R6 Captive Caliper Bracket

Rear wheel changes can be a real pain in the ass especially if you are in a rush in between races! Quick change systems are stupid expensive but captures calipers are a cheap and easy solution. With a captured rear caliper that is permanently attached to the chain puller wheel changes become much easier If you add captured wheel spacers that don’t get knocked out with the slightest bump against the swing arm tire changes become a breeze. I make these from good used parts that I bead blast to a nice clean finish. $60 includes shipping to you. These are $130 plus shipping at Fast Frank’s website. I do mine by hand with a dremel so theirs are definitely prettier. Mine are easier on the wallet so you gave more $ for fresh tires! NOTE! The $50 is conditional upon you sending me your existing rear caliper hanger support and the right side chain puller). Add $40 if you want to keep your old parts and not exchange them. Do NOT include your chain puller adjustment bolt, the little metal “support pad” or the rubber boot with the exchanged parts.

2 Custom Sized Neoprene Fork Covers (All Colors GEN4) 2 Custom Sized Neoprene Fork Covers (All Colors GEN4)

1 pair of Gen 2 neoprene fork covers for inverted forks. Includes 6 black releasable zip ties. These standard size fork covers will fit sport bikes with inverted forks that have an outer tube diameter (at their widest point at the fork seals) of 52mm - 62mm diameter or circumference between 180mm-195mm. They will fully cover the inner tube up to 177mm when completely extended.

The photo shows which measurements I need. If your forks don't fit in this range I will make Custom covers for only $10 more than the price as the standard Gen 4 covers ($35 including shipping).

Round your measurements UP to the nearest option in the list below. You will need to lift the front wheel of the bike off the ground in order to get the Extended Inner Tube Length. Measure the outer tube at the fork seal location where the diameter is largest for the Outer Tube Circumference or Outer Tube Diameter. Please use millimeters for both measurements.

Gen 1 fork covers are made with low grade SBR neoprene. Gen 2 and 3 fork covers are made with higher grade neoprene made of 70% SBR and 30% CR. 100% CR grade neoprene is the type of material used for wet suits. I'd love to use it but my fork covers would be twice the price if I did. The differences between Gen 1,2, and 3 are minimal. They will all work, but I fine tuned the sewing details and a few minor design elements from one generation to the next. Gen4 fork covers use thicker and stronger polyethylene thread, and make the taper in a more precise way. The taper helps the cover fit better because the inner tube is always a smaller diameter than the upper tube. I also sew the hook and loop velcro patches on with a much stronger stitch pattern.
