Jspeed Custom Mid-Race Bike

[JAGspeed@XMR]

OK here it is. My newest mid racer. I custom built this bike to race in the mid bike class. It have many trick parts throughout this bike. It starts with a perimeter frame and aluminum swingarm. I used fastace fully adjustable forks and shock that have been shortened and modified to suit the road race profile. The wheels are standard X-18 gear. The front brake is a Tokico with a nissan master cylinder and 180mm disc. The motor is a 150cc OGM with lots of mods including a custom built exhaust system. I used bodywork from Minimoto madness made for NSR's and YSR's. I had to cut and modify all the bodywork to fit. I had to custom make many of the parts for this bike to make it all come together. The bike ran good at Sandy Hook, it is fast and handled great. Just need to to some minor jetting changes to make it run perfect and have Doug at XMR do some trick Graphics to finish it off.

well you have my props, good job i like the swinger, front shocks, and LOOK its a piggy back!

Now that is very close to my ideal bike...not quite but damn close. Jag don't turn you back on me at the track or you'll wake up in Shanghai and I'll be racin' and smilin' bluelaugh Yeah I'll feel bad knowing you're cleaning toilets on a barge somewhere but hey nothin' fair about a fight bluelaugh Yes I'm punchy I'm on 14 days of doubles straight (12-16 hours) in the Georgia heat and this damn hurricane Fay and her rain.

[The Nutty Professor]

Of course Jag you know I'm going to have questions about things The Nutt thinks are thinking_smilie Is that a X18 shifter system and if it is how well is it working? I can see the none folding pegs which on a race bike is a damn good addition. On the rear-set what's the thickness on the mounting plate I ask because I was having flex problems with some stuff I thought would be more than thick enough. I see major perks with the detachable sub-frame. You can lengthen it for a larger person raise it or lower it and have different locations and heights for a shock mounting tab. Last thing that looks like a Pit Bike swingarm? How did you get a Mid Bike tire and rim fit in there?

Are those HondaNSR50 Fairings?!

Hey Nutt, The shifter is a modified CBR setup, much more precise than the X-18 one, it works great. The rear set mounting plates are 1/4" thick and don't have much flex. I also have the option of changing them out if I need a different peg position. I set up the ergo's on this bike to fit me at 5'11" it is comfortable for me. The subframe is removable and could be changed with a couple of simple mods if needed. The shock does not mount to the subframe. I made a removable mount on the swimgarm so I could use a different mount to achieve other leverage ratios or change the ride height if needed. Using the dirt bike swingarm was tricky. The X18 arm is an inch wider than any aluminum one I could find that would work. So I had to make everything fit into the smaller space. First I spread the aluminum arm out about 1/4" with a scissor jack, I needed ever bit I could get. I had to make a special rear brake bracket that was thin enough to clear the arm as well as the rotor bolts then I made my axle spacers. Everything barley clears, but works fine.
By the way I've never been to Shanghai, but I could sure use a vacation.cool_smilie I think all you need for your delirium is less time at work and more time on your bike.bluelaugh

Less time at work ain't happening any time soon thumb_down CBR part mmmmm candy. Those I can probably find easy and I know what I'm getting. I love and hate Honda all at the same time. Don't dis' my boy Nicky angry_red

Hey Jagspeed what frame is that your using?smokin_pimp

[X7rocks]

jag bike came out great ,any vids on how it was at sandy hook?

[boonacka]

nice bike jag, thanks for letting me take a little cruise on it. This would also be my ideal purpose built midbike. I think the frame is more rigid than the other factory midbikes which would make it alot more responsive and stable on the track. I did notice the responsiveness when i test rode it. definitely needs a steering stabilizer. Now i need to build mine so we can compete!

what size(mm) were the clipons again?

[Shooter]

Nice bike as always!
You XMR guys really know how to build 'em right.
I'm surprised what you said about the swingarm in that you said you stretched it open wider with a scissor jack, I considered doing that when I first got my swingarm but became concerned when wondering what would happen with the structeral integrety of the weld seams. The bends that were already in the aluminum didn't sit too well with me either since it appeared there was possible pinching happening in the bends. I finally broke down and decided to build my own swingarm just for the overall safety of it.
If all works well for you then props to you and I tip my hat off to you bows_smiliecowboy
I'm probably doing work that most likely isn't necessary..... oh well!
Anyway, really nice bike you have there! thumbsup2
Next time I think I'll have you guys build mine for me!

what size(mm) were the clipons again?NOW i know why it steers the way it does and needs a dampener badley.There's quite some contributing factors there.1 the front slick the low arc design.2 the leading axle but the most important is the triple trees.The reversed angle triples.When ever the fork legs are placed in front of the triple tree stem.That will give it the rapid side to side steering response.If he could flip the triples so that the triple tree stem bolt was leading.That will taking away from the funny steering situation.It will also shorten the wheelbase of the bike too.My brains was on foggy that day at sandyhook.(do to lack of sleep)There is a tech term for this setup on the triples i forgot it though.thinking_smilie

[JAGspeed@XMR]

Hey Guys, Here are some answers to your questions about my bike. Rene,The frame is a perimeter dirt bike frame. Boonaka ,The clip-ons are 48mm. Shooter, I did not what to stress the swingarm to much that is why I only bent it 1/4" It was the minimum I needed to make it work. If I had to go any wider I would have cut and welded the arm. Swheels, You are right about the steering and part of the reason it has that quick feel. I did give the bike a fairly aggressive rake angle by raising the rear some so that also makes it turn in fast. I know what you are trying to get at with the triple tree it is called the offset, which is the distance between the center of the fork and steering stem. I used a standard pit bike triple clamp so I did not have much say as to the amount of offset I was using. For road race application I really need a custom made clamp with less offset. I may get one made. For now I have installed a steering dampener.

Man if sava made a front slick that had more of an arc to it.Or had the same profile as the tt91 dunlopes.That would be such a big help also.

I'd love to have a front slick with the same profile as the tt91 dunlopethinking_smilie

Jag,

how much did you cut the rear shock down?? did you cut the housing and the shaft? if you cut the shaft did you have to re-thread the shaft or was it taken off the other end of the shaft?.... I am looking at one of those shocks or a simular version but they are quite long stock, if I can shorten one it may work out on my project as well...

any info on how and what you cut would be appreciated..

Randi

[cj8920]

Where did you get the Fastace Forks from and did they just bolt right up?

[Supercharged]

gotta get some track footage soon

I didn't have to cut the rear shock. I just had to do the forks. I did change the mounting position on the shock to give me a different leverage ratio and less travel . I had to use a specific shock with very little shaft length so I did not end up with to much travel.

[TomHines]

Jag you and your team should start selling fairings... You would make some good money.. It looks like that is your specialty.

[JAGspeed@XMR]

Finally done with the graphics on my Race bike. Compliments of Doug@XMR. Just need to do some fine tuning and I'll be ready to hit the track.

[X7rocks]

jag you should just be raceing taht against nsrs and other higher priced bike that is no x bike but its still :phat:

[doubleu82]

OH MY GOODNESS!!! THAT THINGS IS SAWEEEET!!! Great job! thumbsup2 I'd be too scared to race it. Too afraid I'll mess it up.

[Niusiic[latvia]]

that look bad asscool_smilie

[Kurlon]

Nice build! That Coolster/Apollo frame looks perfect for that application. Almost makes me want to toss some bodywork on my 70... Nah. :P

[doug@xmr]

I'm not one to brag but DAAMMMNN!!
Incase anyone was interested this bike landed JagSpeed the #1 plate for the 2008 season in the Mid bike classthumbsup2Golf clap....

:clap::clap::clap::clap:

Good call on fitting the dirt bike frame/swing arm to road profile. Very nice bike. Where do you guys build at? Machine shop? Garage?

[Unproracer]

Good deal, they make a living at it huh? Man, i wish. I wouldn't leave work but to ride...have all food delivered and minimize sleeping time, just build dope bikes.... Lucky theres no shops like that around here...banghead

Thats pretty much how they do it.They do custom builds for customers, repairs,parts,sales and have pretty good resources to pull from.It's like 5 of them if i remember and i think the qualifications is you must be able to ride as well as fix the bikes.LOL I use to work at a shop.But it was nothing like theirs.LOL After awhile i hated it most of the people that came in were idiots.It got so bad plus the other mech quit on me so i had a lot my plate.I didn't have the time nor did i want to work on my bike.

So now i won't do it again unless the people i'm working with is moving in the same direction as me.(racing modding and developing)

So i give these guys alot of props cause they stay on top of their game.Plus they race what they sell.They also are willing to help anybody get up to speed on these mids.thumbsup2

I used fastace fully adjustable forks and shock that have been shortened and modified to suit the road race profile.

Hello JAG. I stopped by the shop one Saturday early last month with my three children on the way to my parent's house. I wanted to know how to get there in case I needed some work done in the future. Well the future is here. I have received my fourth set of forks and might have something that will work, with a little work. I now have a set of Fastace AS-02's. What does the "shortened and modified" consist of? Better yet, how much would it cost to have mine at least shortened to suit my X-18? I'm starting to get excited again, and all I want to do is get this thing street-legal. Then I might try to sell by big bike.

Thanks

It is hard to say what it would take to do those forks. My forks are AS-01's and were not to bad to shorten. I was able to use a couple of spacers, compress the stock springs enough and change the oil capacity to make it work.
The AS-02 fork uses separate rebound and compression in each fork leg so I'm no sure how they look internally. I would have to take them apart to see how it could be done.
The other issue may be the steering stem. The X18, I believe is different than the pit bike so you may need a custom stem to use the fastace triple clamp.
I also had to make a custom axle and spacers to go from a 12mm diameter on the fork to 10mm on the wheel.
You could bring the forks and triple clamp to XMR and I can take a look at them and let you know if it is worth doing and how much it would cost.

Sounds like a plan. I had a machine shop looking into custom stems for me, but these bikes are your specialty. And if it can be done XMR could be my one-stop shopping spotbows_smilie or at least point me in the right direction. My wife goes on travel tomorrow, but if it is slow at work I'll try to head up there. I'll be giving you guys a call.

Thanks again.

Sounds like the East Coast, north and south, is becoming the Mid Bike place to be. The left coast has the tracks but we got the talent.

I know what your saying. I live in Washington and my friend and I are the only one, that I know of, that have mid bikes. the weird thing is we both have x12's. Everyone else rides quads or dirt bikes.

Where is the XMR shop located at?
