I've changed my mind about how radical I want to go in the time that I've had the bike and become more and more fond of the current looks. I was originally intending on a swap to some wide 17" wheels and possibly a swap to a SSSA, but I've decided now that I want to keep the stock geometry (or very close to it), stock ride height (or maybe a -0.5-1.0" higher), and my CB1100F golden boomerangs. No interest in any frame bracing/mods at this point.
I'm going to keep all info I discover about having this work done here in this thread.
Here are the options I'm considering currently:
Definitely swapping to handlebars and keeping stock gauges & controls. Don't care if I keep the stock fuse box and ignition key location or not. Good cartridge internals sprung and damped for me & the bike are mandatory - nothing with damping rods or emulators. Better calipers would be nice, don't mind new rotors but I don't want them much bigger than the stockers or they'll obscure my wheels.
- Keep the stock forks, swap the internals with good cartridge stuff, custom over-top triple setup like Randak's to mount the bars, but styled more to my taste. Keep the 2-piston CB1100F calipers I already have.
- 43mm RSU cartridge forks from a bike of similar size/weight (probably a Bandit 1200) with some upgraded/tuned cartridges. Will probably need custom triples, definitely need some spacers & bearings sorted out to work with the current front wheel & speedo drive, and custom brackets to mount the fender. Would use the rotors & 4-piston calipers from the donor bike.
- 43mm USD cartridge forks from a bike of similar size/weight (probably 'Busa, or XZ-14), valved & sprung for me & the bike. Again, custom triples are almost definitely necessary. Again, would use rotors & 4-piston radial calipers from the donor bike (I really like the looks of USD+radial, so would not choose USD forks with an axial caliper mount).
Another pro for #1 is that the forks are definitely long enough to let me add that height - might take some very tricky triple clamps to manage it with modern forks unless I can score oddballs from a road-focused adventure bike like a KTM 990 SMT, Buell XB12XT, or Tiger 1050.
Options #2 & 3 are probably similar level of difficulty & cost, and the same performance for a rider like me - the decision there is which look I prefer. RSU's would look OEM, USD's provide the bling... Either one would make talk of flex irrelevant and better braking than option #1.
Definitely keeping the twin-shock setup, and definitely going with some good shocks that are adjustable for compression, rebound, and preload (but probably not remote/hydraulic preload) with straight-rate springs. I would like something better-looking than the stock swinger, and something that will take readily available bearings for ease of maintenance. Stiffer would be a nice bonus, but isn't a primary concern.
The shocks I'm considering that meet my requirements for quality and appear to be available for the CBX are:
As for the swinger, I want to keep stock length. I would like to raise the bike overall a little bit (0.5-1.0") if it can be done without messing with the chainline too much. Options I'm considering include:
- Mod the stocker to brace it and rework the pivot section to take new bearings that are more easily found.
- Find a suitable donor alu swingarm and have it modded to fit & work with the twin-shocks. If I go this way, I want a box-section swinger, not the kind of bulky units on modern sportbikes.
- Have something custom built from scratch.
Plenty to think about. I want to finalize all decisions in the next 2 weeks and have my parts in hand by the end of Oct. All I know for sure at this point is that I am VERY EXCITED about getting these upgrades done over the winter so I can ride the bike with more pleasure & comfort next year.
I think I'll keep a running list here of my current plans & what ends up actually on the bike:
- Swingarm: Chromed aluminum from TRAC http://tracdynamics.com/pages/swingarms
- Sprockets: 43 tooth black rear Stealth from Supersprox, and an 18 tooth front from CBX Performance. https://www.supersproxusa.com/Products/ ... ockets.php
Note: My local retailer and/or Driven screwed up and I was sent the wrong sprockets and chain and told that they don't have a fitment for the CBX. Some of the folks at Driven supposedly have some CBX history - but it didn't seem like anyone involved in the screw-up wanted to work with me to get it sorted so I have no interest in ever giving them a dime.
- Chain: Black 530 X-Ring chain from Supersprox
- Shocks: YSS RG 362-360 TRCL-09 w/ optional compression adjuster http://www.yssusa.com/series-g.html - the valving on these looked pretty bad on the dyno, so they were revalved by Rick at Cogent Dynamics http://www.motocd.com/
Note: After getting the YSS sorted out, I learned about the Ohlins HO 146. It has the same 4-way adjustability (preload, rebound, compression, and length) as the YSS, and the valving should be good to go out of the box. http://www.ohlins.com/Our-products-new/ ... rt/HO-146/ It's spec'd for a CB900, but Dan Kyle may be able to provide them ready to go on the CBX - although this may require some mods to the bike and/or shocks to get them to fit. http://www.kyleusa.com/ The cost for the 146 is about the same as the cost for the YSS + revalve.
- Forks: Pro-Link forks rebuilt with AK-20 cartridge internals from Traxxion Dynamics http://www.traxxion.com/ and new tubes from TNK (available from Race Tech) http://racetech.com/page/title/FTNK%20Fork%20Tubes
- Triples: Custom top & bottom
- Front rotors: 310mm 2007 GSX-R1000 rotors, custom adapters
- Front calipers: 65mm Brembo axial mount 4-piston, custom brackets
- Front master cylinder: Bandit 1200, custom stainless lines
- Footpegs: 1" drop pegs from Knight Design - they don't make a CBX peg, and these will need some tweaks to be able to fit. http://www.knightdesignllc.com/Products ... _Pegs.html
- Bars: LSL Superbike Fatbar (I had to ditch the CR High Pro Taper Contour bars http://www.protaper.com/products/handlebars/contour because they didn't work with the CBX switchgear), with a KTM Duke 690 clamp assembly - chosen because I know that they work perfectly with the KTM GPS mount, which I like a lot. The bars may need some modification to fit the KTM clamps. http://www.spieglerusa.com/controls/fat ... ebars.html
- Gauges: Speedhut - they offer an incredible array of customization, each gauge set is made to order. I hated to do it, but I had to ditch the stock speedo because the rotor adapter precluded the stock speedo drive unit. I ordered a matching speedo, tach, and clock (which will replace the voltmeter) from these guys. http://www.speedhut.com
- Oil cooler: Earl's 13 row cooler plus a Thermostasis 190°F thermostat, plumbed with AN-6 braided lines and black fittings. http://thermostasis.com/
- Stands: sidestand and centerstand were both lengthened a bit to account for the increase in ride height. The sidestand was cut & welded, the chromed centerstand had some stainless feet added to the bottom to get the rear wheel 1/4" off a flat, level surface.
