Okay, so for Christmas my wife got me an 06 SV650S. It has been down and has been sitting for the past year and more. I started working on it this weekend.

I am planning on doing a bobber/streetfighter theme with it. I was really inspired after reading Cabbies thread about Kwikasfaki. My skills are nowhere near the level of Cabbies, but I will do my best.

This build will happen very slowly as I am on les than a shoestring budget with it.

I stripped the entire thing down, I removed all the bodywork, the front subframe, gauges and lights as well as the rear subframe.

I am going to mock up my own rear subframe brackets and seat pan and have them machined. I am stealing the method of using MDF to creat the templates from Cabbie. Thanks for the great idea!

I will go with GSXR forks, eventually. I want to get the ones with the black tubes and radial brakes, but I need to research which bike those came off of.

I am going to relocate all the electronics to the airbox. I have no idea if this is a good idea or not. Any input here would really be appreciated.

Okay, I am having a bit of a design dillema. I mcked up two different style of trusses for the seat support. I am torn between them. One is a trellis style, the other is an open stly. I did the trellis one first, it really matches the frame well.

Then after looking at it for a while, I thought it might look cool open. So I made some open ones. I love these too.

Can't decide!!!!

What do you all think?

**Triple R** · 01-03-2012, 02:15 AM

I like both subframes and can't decide either. If you want black radial forks you'll want 06-10 750 forks. I would also suggest a set of 09 GSXR 1K brakes or the usual r6 (05+) / r1 (04-06) setup.

**Crashing Sucks** · 01-03-2012, 03:05 AM

I can tell you whatever you want to know about that bike. I also have some parts for it if you need. DO NOT use the front end with the black coating (gixxer1000) the Showa front end is better and the brakes are the same. I have a front end from an 05 gixxer 600 and it is far better than my gixxer 1000's Kayaba front end. Also I am running a 636 rear shock which is a direct bolt up. (some will tell you need to cut the battery box but thats not the case) You can also run a 2006 gixxer rear wheel and run a 180 tire. The second subframe looks best BTW

**mythic44** · 01-03-2012, 07:08 PM

Thanks for the replies fellas. I appreciate it.

Crash, what makes the 600 forks better? Adjustability? Thanks for the shock info too! I will be doing that soon. The battery box is completely gone so no wories there anyway.

Any thoughts on my idea of relocating all the electronics to the airbox?

Also, I was thinking about the exhaust, how important is it for both pipes to be equal length? I want to do a custom set up but it would make the rear cylinder exhaust pipe very short.

**!ThatGuy!** · 01-03-2012, 07:23 PM

I put the gsxr 1000 rear shock on works wonderfully, though I did have to cut the battery box. Should have gone with a zx10 shock.

**jandcwright** · 01-03-2012, 07:37 PM

make a third subframe. make it match the mainframe from the forks to the subframe mount just smaller. just my .02

And how high is that seat? that looks like its way off the ground

**mythic44** · 01-03-2012, 07:49 PM

JandC, the first one matches the main frame. That's why it has the trellising. The over all shape on the subframe is dictated by the mounting points at the bottom, so i can't make it a diamond like the main frame. Thank you for the input though.

!thatguy! which GSXR 1000 rear shock did you use? And you mention using a zx10 shock as well. Which model ZX10 fits in the SV? Or were you meaning the 636 shock that Crashing refered to?

The seat height where it meats the tank is 31". Yes it is high, but I have a 34" inseam, so I am fine. Also, this bike is mostly about the look, so I am making some sacrifices in the practicality department. For example, the seat will be unpadded aluminum.

Needless to say, this will not be a touring bike! It will be for short blasts and hopefully for a show or two when it is all said and done.

Again, thanks for the input everybody.

The Showa front end just moves oil better it seems, even cold it seems to give better feedback than my Kayaba front end. On my 1000 I have resprung it 3 times in hopes of making it feel better without much luck. It seems vague until it has had tome to get hot. Once it is warmed up it is much better. The 600 Showa front end is great right out of the garage. It gives you a lot of feedback when warm as well. I have pushed the front while cranked over 3 times last season on track. and each time I felt it coming before it happened. The Kayabas on the other hand aren't so forgiving. Some of that i will chalk up to Tires though. I can definitively tell you that i love that 600 front end much much more. Adjustability is the same as far as wrench turns go, I found the SV to easily suit me in stock form while the 1000 required alot more tweaking. One thing I can deffinitly say about the 600 front end is that the rebound is much more responsive than the 1000's .
Wiring in the airbox probably is not a great idea due to the heat. You might want to think up a small vented compartment inside the new subframe for that.

**mythic44** · 01-07-2012, 03:44 PM

Thanks for the info everybody.

Regarding the wiring, I am going to do a litle more thinking on what to do there. I was thinking in the airbox would be a great way to get everything out of sight and still totally protected from water and what not. My reluctance to make a tray for the electronics under the seat is that I was trying to keep that area as clean/open as possible. I am going for a very minimal design asthetic.

I am very close to being on board with the 600 forks. What year are you recomending Crash?

!thatguy!, which GSXR shock are you using? I would love to keep thing as Suzuki as possible.

Also, any thoughts on my exhaust question? I have an idea for how I want to do it, but like I said, it will mean drasticly different lengths for the pipes.

One last thing, I have decided to go with the open subframe as opposed to the trellised one. I am also not going to have them CNC'd out of aluminum, I am going to try my hand at laying carbon fiber. I can get all the supplies I need for $200, so even if it doesn't work out, I am not out a fortune. If I can get the subframe to work nicely, I am thinking I will do the seat in carbon as well.

I have more research to do on what style weave is strongest and how thick/how many layers would be needed to get enough strength to support my 210 lb butt.

Any input and suggestions are very much appreciated.

**mythic44** · 01-07-2012, 03:52 PM

Hey Crash, you mentioned in one of your posts about running a 180 rear tire on a gsxr rim, is that a direct bolt on? If not, what else would I need? Pretty interested in this.

One other thing, I feel like I read somewhere that Hayabusa pistons drop right into these little motors, is that true? What sort of gains would I be looking at from something like that I wonder?

Again, thanks everybody for the input.

**Crashing Sucks** · 01-07-2012, 07:20 PM

HAHA, I dont know about the Busa pistons. The front end I have is a 04/05 GSXR 600/750. It will give you Radial Master Cyl. and Calipers. You will need the wheel, axle and rotors from the donor bike also. You will lose your speedometer with this mod.
The 180 Wheel and Tire are not bolt up either. The wheel you need is off a 06/07 gsxr 600/750 and you will need the sprocket carrier too. You will need to send your Rear brake caliper bracket from the SV and sprocket Carrier from the 600 out to be machined down to spec. They will make customer spacers to go into the wheel and you will be able to use the stock axle. it cost about $160 for the machining and spacers and what every you can find a wheel for on fleabay. If you want to do it I can get you the guys number. Also you can get it here http://www.twfracing.com/PartsPages/gsxrwheelconv.html

**SpeederT** · 01-07-2012, 07:29 PM

I like the second set up, but take some of the angle out so it flows better.

**mythic44** · 01-07-2012, 10:34 PM

Hey Speeder, thanks for the input. It's on stands in the second picture about 3" off the ground. When it's flat it doesn't look as extreme.

**jandcwright** · 01-10-2012, 09:59 AM

in the first pic make the bottom triangle into a diamond shape is what I was thinking. Either way looks good though

.

i have an 03 gsxr 1000 rear shock. works like a dream. but i had to cut the battery back, get a smaller battery and raise it up. the zx10 shock ('06 i think) doesnt require any cutting of battery box and has more adjustment capabilities i think.

as far as exhaust goes, i love the look of the M4 gp style, but its mega loud and requires a little fabrication. well worth it all imo though

Are you talking about black fork tubes???? These are from a 1000 and are Kayaba made

Or black fork sliders???? These are from a 750 and are Showa made

**!ThatGuy!** · 02-15-2012, 10:57 AM

any update pics?

**mythic44** · 03-18-2012, 09:06 PM

SPL, the black fork sliders are what I was refering to. Thanks for the clarification there.

Thatguy, no pics yet. Soon though. I am working on the seat and supports right now. They are carbon fiber. I also decided to create a box for the electronics under the seat pan rather than in the airbox. Also, I am going to rmove the top of the air box. I have read that the added volume can add a bit of power and a lot of growl. Unfortunately, at this pace, it will not be ready this year. But that's okay. At least I have the big K5 to ride in the meantime.
