I am interested in ideas for a new sportbike. Thinking along the lines of say... a Bimota or Segale. The powerplant will probably be an SV650 with an overbore kit on it. The current big picture goal is a light single seater fully faired sportbike. From there I am looking for ideas. BTW, I do want this to be something that could sell also therefore no carbon fiber frames(too expensive).

This is currently just a dream but I would like to make it a reality. Depends on mine and the wife's jobs.

Please try to keep this as serious as possible. I will print this stuff out for future use. Thanks.

John:

For what its worth,I just got my December issue of Motorcyclist. It has lots of current year bikes and pix and "latest new bikes on display in Germany".
For my money,(and if I was Bill Gates or someone like him...),I'd LOVE to have an MV Agusta F4S.Single sided swing arm,the exhaust system that exits out the tail section...these things are a work of art!!Ducati will have a sport-tourer powered by the 996 motor. Lots of 2000 and 2001 eye-candy in this issue!!:):)
Keep us posted on your thoughts!!

John,I`m assuming that you will probably want to use as much stock items as possible eg.GSXR rims,levers,nissin calipers to keep the overall price down or do you want to maybe have half and half eg.marvic rims with stock brakes,spondon frame with stock bodywork.Do you want poeple to notice this bike or for it to look like another SV650?.How about black rims,swingarm and frame and red fairing or a blue like the ZX9R.

well, i personally like the tube frame idea's.. u can build them light & strong. of course an under the seat exhaust w/a lot of room btwn the tail section & the tire.. like on the polaris bike. something that really seperates & identifies a bike is the head light configuration.. yamaha set the new standards in my opingion so u r going to have to go a step further... maybe a flat upper w/ integrated projector lights on the side fairing? ooooo.. i just had an idea.. headlights on the helmet.. that way u see where ever u look.. hard to make them small & bright enough though. i also like the hardcore race set up... high rear sets low clip ons. i like single sided swing arms.. but its been debated recently that the dual arm is better. brembo brakes would be nice. didnt i hear somewhere that suzuki was gonna make an 850 sv? that motor would be sweet too. 180/55 rubber. it would be cool if u could figure a way to make the wheel base short but have the longer swing arm like on the r1/7/6... but the engine was built to incorporate that on the yamaha. back to the front fairing.. i think an xtreme angle would look good.. something kinda pointy but still smooth.. id have to draw u a picture of what im thinking... but if the headlights can be mounted on the side then the possibilities are endless. i remember a front fender called a rhino fender or something or other.. it improved cooling & aerodynamics.. something to look into.

Instead of lights on the helmet,go with lights on the front fender in addition to the normal location or lights on either side of the fork legs and blend them in with the fender.A single sided swingarm from a VFR(should be cheap to get)but you would be limited to a 5.5 inch rim.Here`s an idea thats a little too far out but a hydrostatic transmission(the engine drives a hydraulic pump and the oil drives the front and rear wheel).Belt drive(chains are too messy and shaft is too heavy).

From what I have heard, it's difficult to have a long swing arm on a twin. Somthing to do with the angle of the rear facing pot & having no room for the rear shock. (see Buell, Britten, TL1000 etc)

However, having a shock mounted beneath the frame fixes the room problem (see Buell, Britten):)

I also agree on the tubular frame idea, it should be easier to construct.

This is exactly what I'm looking for. Actually it is scary how much we think alike. :eek:

Pete kiss my ass. :D:p

My current thoughts are:

Spondon frame and single sided swingarm.

Stock brake components(probably).

Modified bodywork similar to the Sharkskinz that Mongrel has with the solo seat.

I was thinking about a high rise dual exhaust. Considered the undertail thing but it seems too over done these days. I don't know.

I was thinking three projector beam lights following the fairing upper from centerline up one side. Sort of like the Benelli but you know... different.

As for stealing ideas... this has been discussed in advance with a couple of other SBW members. Auger was pretty much in line with the discussions. ;)

I like the bodywork ideas. Lights in the fender is an interesting idea. I was thinking LEDs incorporated into the bodywork for turn signals and brakelights.

Keep the ideas coming. This is fun. :)

How about turn signals in the shape of arrows consisting of LED`s(maybe 30 LED`s per signal)built into the tail portion and front fairing.A centerstand that really tucks up out of the way.A flip up licence plate for when the cops are being a nuisance.(that would work really good up here because the cops use photo radar).A couple accessory(12 volt)jacks for electric clothing,chatterbox,radar detector etc.A proper loud horn that doesn`t sound like it came out of a Crackerjack box.If you could hide it,a air horn(you could have alot of fun with that).Adjustable pegs for different sized riders.Shorty clutch and brake levers so they`re more crash survivable.Darn you John,now I can`t stop thinkin about this project bike.

Well you have to put neon lights underneath, But they only activate when you wheelie! How about an air horn ? Dont forget highway pegs.....

i like the spondon frame and swingarm idea. harris is another idea.

i'd put a gsxr600 front-end on it for the adjustability. usd is over-kill and over weight for a little bike like this. i'd use the gsxr clip-ons, controls, brakes and front wheel (makes it simple). then i'd update with ebc hh pads, ss lines, and maybe even some pro-lite rotors (they look neat).

penske shock (fox if i couldn't swing the expense). i'd buck the trend towads under-seat pipes, and go practical with a full m4, they make an excellent sv pipe.

i see aprilia rs250 upper and lower, with small projector beam light in the ram-air hole (no need for ram air and the airbox would be very pricy for the gains, hell maybe even mix in some old-school and throw on a pod filter and dump the airbox all together, sure it hurts drivability, but...). off the bodywork subject for too long, and i'd use a tz250 tail section, the pointy anti-draft one.

maybe some rear-sets...

okay, now we are starting to see one of teh two reasons i didn't buy an sv.

I have looked at Harris frames also. They are pretty spendy. Spondon has the single side swingarm for the SV but doesn't have a date on when the frame will be done.

The mention of the Aprilia is kind of funny. That bike is what started the initial discussion of this project. I mentioned to a SBW member that it would be interesting to put an SV motor in an RS250 chassis.

I definitely think adjustable rearsets is the way to go.

The M4 idea is also a good one. I was considering trying an inside connection to see if they could develop a dual exhaust for the SV motor.

I like the full adjustability of the Gixxer front end but most of the Spondon frame kits come with Ohlins shock and fully adjustable forks. So I will have to wait on this.

As for production, this would be nice. I guess that it would depend on the acceptance. Also, I think to be reasonable and profitable, I would have to be able to fabricate bodywork and frames in house. Otherwise, they would have to be rather expensive and built upon order. The President of our company has said that he wants ideas for our manufacturing division. I have already brought up the idea of making race stands and the such... at a more reasonable price. :)

This is a fun project to think about. Sure wish I had some money. :D

LOL!! :D:D

I actually lose sleep thinking about it. I am racking my brain to think of how to finance the project without selling the RC 51. ;)

when i mentioned tube frame i was under the impression u did mean that u would produce your own... & actually fabricate as much of the bike as u could around the engine.. kinda like bimota does.. correct? that way you could set your own rake & trail, ride height, etc...

i think it would be great for you & your company to put out a quality, inexpensive race stand... i dont see why they are so expensive n e way.. i mean for the most part they are just a piece of $.50 metal tubing.

& i dont care if everyone & their momma is doing an under seat exhaust.. they do it for a reason.. it looks cool as hell.. & it keeps the pipes out of the way. i think a set up like on the agusta f4 but w/2 pipes would look cool.. maybe have the exhaust pipe out the side of the back part of the seat.. on the side.. with out the pipe sticking out.. more like a vent.. then fabricate a piece of metal to fit in the vent well to protect the fiberglass... or maybe have the 2 pipes come together under the seat & exit out of a single rectangular tip that sits under the brake light.

integrated frame/body sliders would be nice too. i like the idea of shorty levers. led turn signals.. damn u.. i was gonna do that on my bike & make it a big surprise. digital speedo.. but a regular tach. i didnt consider that a longer swing arm is more difficult w/a twin.

Yes, a tube frame like the Spondon and possibly nickle plate it,although I`ve never been a fan of bright shiny pieces like chrome on a sport bike.I like the approach that Honda has done with the RC-51(black frame,swingarm and rims).John,if you get this bike off the drawing board,maybe the contributing members on this thread can be shareholders in your company?.
