How to fit Emulators to a pointy

Urban did post the dimensions of both Emulator and Damper rod. Is it possible that the RT's dimensions are different, hence the need for an adaptor for the Debrix?

Entirely possible that the various emulators are different sizes. In the original post there was no mention of Debrix versions being used, the only mention was of some adjustment figures from RaceTech.

Cheers for this discussion and clarification. It all makes a lot more sense so decisions, decisions ...

Just checked in the RaceTech catalogue. The part number recommended for the pointy is FEGV 4101. For the curvy its 3801. The first two numbers refer to the outer diameter of the emulator, suggesting that they are designed for different diameter fork damper rod tops.

They were Debrix ones, does anybody buy Racetech ones now Debrix do them for 1/4 of the price?

I'll edit my original post to say Debrix.

To be honest I feel a little uneasy about buying what is in effect a copy, made in China I think. Each to their own I guess. I have no idea if RaceTech actually patented the design, maybe they didn't and that's their tough luck. However, I assume RaceTech did the original development work to create these emulators.

I suppose this is no different to buying a full price DVD in the store, or using a copy from the local market. Totally depends where you stand on the issue.

I've used RaceTech emulators for years on SV, FZR400s and vintage MZ race bikes. I've found them good quality, had good customer service and valuable suspension tuning advice over the phone when I've needed it.

Thanks for the pics very helpful.

Did the emulators make much of a difference?

Also, just a thought on the debate over the adapter rings that you made. Given that these emulators are basically the same with different sized ODs and stepped boss ODs, perhaps another slightly simpler approach would be to buy emulators with a bigger diameter step and turn them down on a lathe to suit the dampers they are being fitted to? Would save you needing to make a separate adapter.

I don't think the Debrix comes in a different size. Tbh, I'd rather spend the money on a GSXR swap than RT emulators. The Debrix is just cheap enough to give it a shot. No real loss if it doesn't work. If it does then by the time I'm done with them I'll be done with the SV. The spacer, apart from cost, isn't a big deal. It either works or it doesn't. The comments on this forum says it does so I'll give it a shot with the spacer.

go for it. The difference between standard damper rod forks and those modified with emulators is enormous, well worth doing.

Geese and Runako, i gotta say they've made a noticeable difference, enough to impress, less 'bounce' at the front in normal/commuter riding and seems like less pogo dive when braking hard initially. I'm still running standard front springs so being progressive they'll still be soft on their initial travel, but its well worth doing, hard to say how much is the emulator and how much is the thicker oil, but for about £50 all in its definetly worthwhile doing. Hardest part was getting the bike front end up in the air. I've now made an ABBA-style stand for upcoming jobs! Locating pins fully adjustable just like the real thing! Haha. Just needs painting.
I had a chance to ride my Sv pretty hard since doing the forks and i can't be more impressed for how easy it is to do. It now shows up how undamped the rear is, whereas before i didn't notice as it matched the front. I flew up **** Hill recently. Bike was leaned right over, unfazed, no twitching, wallowing, nothing, thats matching my Fireblade on that bend. Proved to me how much more confident i'd become to push the bikes limit without actually realising till i thought about it after. Its still only a budget motorbike, but one that small improvements can make a big difference.
Regarding the quality of the Debrix ones, search any threads mentioning them and they will say how good they are. I'm a precision engineer by trade, and an anal one at that , i don't know how they make them for that price, the machining of the component was perfect, chamfered edges, no burrs, material imperfections or chatter from the cutter when machining, annodising was spot on. Just really impressive. And they work fine.
