Thinking of a Mild Supermoto Build

sexy!!!

[rbozz666]

cheap s low tards can go together but for a fast tard its not going to be cheap you can do it as cheap as possible but ur still going to spend some money another thing to consider with buying a older dirt machine is bearings and bushings commonly are worn out which in the dirt is one thing but this will cause bad handling on the street i still say go ktm

Motard baby fuck the world

If you want a track only just get any dirt bike and look for some rims on the cheep. I found some for 800 then upgrade your front breaks. Your better off just getting one that's ready

I want to see pics of this!!! I think I'll have to spend money on the wheels and tires just from exploring the Excel options... or maybe buy them used from the super moto forum or something. Can you elaborate on the suspension ordeal? I'm open ears.

I sold it to grapes little brother or something like that..... cant quite remember. Might have more pics of it at home.
The suspension settings of a dual-sport wouldn't really be geared towards track use, new springs in the front for sure! Mine would bottom out all the time, but thats also due to me being a lard ass

For kart track fun just about anything you build will be fun, unless of course you are an overly competitive type. The cost of wheels has dropped drastically since I first built mine and back then you saw a lot of creative setups. Wheels from streetbikes like CBR600 F2's, SV650's and EX500's were popular to budget minded riders. Mods to get them on were fairly straightforward and cheap. I probably would have gone this route if I had researched a little more before purchasing my wheels.

Brakes are very important as you will need far more braking than the stock setup allows. I warped several rotors trying to get by on the stock stuff. On my first decent setup I ran an EBC rotor and a custom machined bracket to relocate the caliper. I later swapped in a later model fork and caliper that was supported by the aftermarket. EBC has a fairly cost effective kit for most modern bikes that includes a caliper relocation bracket. The folks running modded street wheels usually fabbed up a bracket similar to mine or if a 320mm rotor was available for the wheel, Purchased relocation brackets from one of several sources.

Suspension wise a stock MX set up can be made to work reasonably well for kart track stuff, but most dual sport and trail bikes will need springs and valving work to feel right. They are simple set up too soft for agressive riding. The KLX 250 and 30 are nice little bikes and can go pretty good under the right rider. I would avoid a 2 stroke if I did it again. My YZ250 is a blast to ride, but no where near as flexible or managable as a 4 stroke machine. Don't get me wrong, it handles great and is very fast but I have to work a lot harder than the 4 stroke guys to carry the same pace and it is very poorly suited to street riding. Highly tuned 2 strokes like the YZ or WR simply do not like to crise at a set pace and can easily get dangerously lean doing so. Its not an issue on the track as you are constantly either accelerating or decelerating and never 'cruising' but on the street its at best annoying and possible very expensive. An XR400 is a good choice as well, but I have been considering an XR250r as a fun bike ever since riding one that a friend owns. You rarely need more power than what the 250-300cc trail/dual sport bikes offer.(unless you are that type A kinda guy...)

Gotcha! I was waiting for you to respond since we briefly talked about this when I stopped by... Brakes DEF upgrade, For the cart track 200-400cc's would suit, 2 stroke okay at the kart track but not ideal to keep up, budget minded guys can go with variant used bike wheels (i will explore this further).

Just get a drzsm if money is an issue. Sure they are heavier and *Faster longer deeper harder*Faster longer deeper harder*Faster longer deeper harder*Faster longer deeper harderer than some but they can definitely get down. I picked my 05 up this summer for $2700. I doubt you will be able to pick anything up for much less with a sumo setup and you will spend more if you set one up from dirt form. Just my $.02

Well, money isn't really an issue... I'm not too far in a rush either. I hear you though... I would love to aim for spring but its okay if it carries over into next winter. I'll have to weigh the options based on my desire of when i want to ride this thing. I'm pretty patient.

I was jacking around and found a cool ass site. I've never been the project type or the wrencher (mostly because I'm mechanically retarded), but this looks like a nice place to start for some ideas/kits.

Here is the "bare bones" kit: http://www.motostrano.com/sucokibabo.html

www.motostrano.com has a lot of neat stuff. Hell, I'm thinking about one now so I can hit the Kart track in between track weekends next year!

I checked those out a couple weeks ago... I really like how they have different options. It's pricey but if you want quality, you gotta pay to see it. I want to see what options I have as far as sportbike wheels/tires. I really need to have the bike I will purchase on hand as I have to see things and touch them to understand as far as the hub/axle/wheel options go. Kind of play it by ear if building is the route I go.

There is no "craze" as Supermoto has been around for several years. In fact, it has died significantly since then. I just returned from WI and was hanging out with Mitch from HMC. Let me tell you something about Supermoto in WI and MI. It is FAR from dead and I think it may even resurface. In fact, Mitch is busy with builds he still does and customers coming to him for legit race builds as well as well sorted street applications. Trick components and stuff only that can be had from Europe...

That all being said, supermoto can be cheap. Apparently, you want a streetable version for riding in that environment. Perfectly acceptable idea.

My thoughts are that you need to consider $4-$5k and getting something legit. These wheezer motards are only going to get boring quick and have VERY big hurdles to overcome. If you plan to road race it, you need to consider that into the application also...

For pure street and go kart tracks? My suggestion is buy a pre built Supermoto MX based machine. 250 or 450, but for street use, the 450 is the best choice. The bigger cc bikes are just not as much fun and are heavy, harder to handle, etc. Actually, Mitch builds 450s almost exclusively anymore and the bigger singles are less and less popular... Meaning north of 600cc...

So, check out the interweb and search for an assembled MX based machine. In Ohio, it is as easy as pie to convert to street. Slap a light kit from Baja off Ebay and get her running. You'll smoke th shit out of anything with DRZ on the tank and anything 2 stroke. Trust me.... Cheap isn't always the best idea and 2 strokes are going to give you more fits than you'd get from a modern 4 stroke...

If tracking the thing on a big road course, I suggest 450s being the smallest to consider. Otherwise, the sustained RPMs at top speed are going to murder a crank. Go north of 500cc and do 4 stroke. DO NOT consider a 2 stroker...

If you plan on spending $1500 on that Kaw, I suggest you check into that more closely. Probably need a top end, probably need to add some things as I see things missing. On top of all that, you probably will have about another $1k in to the thing and still be behind the 8 ball... So, save some coin during winter and look at Supermoto Junkie for something on there. Watch CRF450s as they are notorious with issues concerning vavles and adjusting them. Replacing is common and expensive - if you do, ask if they replaced the valves and if so, check for something like Kibblewhite as they have steel based valves that will last longer. But, you will have more in maintenance with a Honda... Look for a Yammie or similar...

Good luck!

Thanks Lizard! I appreciate the time put into that answer. FYI, at the moment i'm thinking very mildly for the application. I don't think I am competetive enough to build something to race, more or less to bring out to have fun on. From what you are saying I don't know if building something specifically for the street and 'real' track days is something I will venture into yet. The way I'm thinking I may just build it for the kart tracks and eventually make it street legal to put around on... The reality is, I probably won't build a monster the first time if I choose to build... more just to learn and have fun.

After I make/build/buy this first machine, I'm sure I will upgrade whether it be selling it or trading plus cash like I've done in the past with cars (somehow I always upgrade). Regardless I'll apply some of the advice you posted above.

Just came.... wait, no that ... UUUUUUUUUUUUUNNNNNNNNNGHHHHHHHHHHHHHHHHHHHLLLLHHHG HHHHH There it is.

cheap s low tards can go together but for a fast tard its not going to be cheap you can do it as cheap as possible but ur still going to spend some money another thing to consider with buying a older dirt machine is bearings and bushings commonly are worn out which in the dirt is one thing but this will cause bad handling on the street i still say go ktm

Personally, I've never railed hardcore on a dirt/dual-sport/motard bike... I've just riden normally since they weren't mine. I likely won't be building anything too terribly fast in the near future - just to be part of the fun. Fast=Money, always has and always will... I hear you on the older bikes... definitely something to consider. It will cost some money to replace things... that is okay.

If you want a track only just get any dirt bike and look for some rims on the cheep. I found some for 800 then upgrade your front breaks. Your better off just getting one that's ready

This is a good point.

I wonder what a two stroke would do... I'd like to build one... I can't think of really any drawbacks unless i tried to take it on backroads, which I don't see doing much if I have a street bike already. are the older xr400's 2 stroke or are they just an older 4 stroke?

It's an older (96 to like 05 or so) pushrod air cooled 4-stroke. Like Bpro said the 250's have decent power too, and I'm about to punch mine out to 280cc's. The suspension just isn't the best. And I think Bpro touched on this but a 2-stroke will be a little harder to ride. You could tame that hit 2-strokes are famous for a little with a heavier flywheel weight, but IMO it's hard to beat a 4-stroke for it's forgiveness and wider torque spread.
