450 Super Mono
In case none of you have heard about this yet, there is a lot of interest in this series for entry level racing. The idea is that you take a 450 motocross bike, retain the frame, engine and swingarm while adding (supersport suspension, road wheels/tires, and a full fairing) coming out with a track bike that weighs around 250lbs and has about 50 hp.
Here is the idea I had, if you added all the extra's to make it DOT approved for road use (lights, mirrors, etc..) you could register it as a dirt bike could you not? Plus I bet you could find have the parts from salvaged bikes and save a bundle to build it. Just an idea |

Im not sure what SC DMV will say, they are pretty lax here though on laws (no DB limit, bike doesn't even need turn signals to be approved)

Yeah, those 450's sure look nice. Roland Sands did a wicked job making the concepts.

Someone i know built a ktm 450 supermoto type bike and has it registered. Now here in Rhode Island many guys have registered dirt bikes (with full lighting kits).

It would be far cheaper to get a decent road bike chassis and put in the engine of choice. The take the offroad frame and add on road suspension means that the rich guys will immediately put on $1000+ rear shocks and $3000 front ends, not exactly what I would consider a budget class.

It is still a cool idea though that I wouldn't mind building on a budget down the road.
Really the only way to stay in a budget racing series would be to use production class rules that prohibit expensive suspension and engine mods. |

It is certainly interesting and brings back the point that I think we need things like a GSXR400.

I'd love to see some inline-4 400's make their way out, on just some sick frames, with the nice brakes, forks, etc.
heck, a 250, set up to run premium fuel (around 40hp), all aluminum frame with all the adjustable goodies, 17" wheels, dual front stoppers...I'd so buy it, even if it did cost 6k. It would be a sick track bike.

A 40 horse 250 would be pretty damn cool, especially if it used a nice lightweight aluminum frame so the total weight was light.

Agreed, I'd be on it in a heartbeat, but you'd never see it, at least not in the USA. It would be way too expensive, especially with an aluminum frame

I've even been wanting to go custom on the 250. Get with a shop, use setups seen on the RS125, and use a custom aluminum frame.
If I can find a super cheap 250, I may just go for it. It would take a lot of design, and I'd have to find out if I could even register it. It would be sick though. Maybe then a dinky 250 on aluminum may seem appealing to the big wigs at the big 4. Since it would be custom, I could design it to accept zx6r plastics too. Hmmmm.... Or find a old aluminum frame on an older zx6r, use the stock brakes, swingarm, etc, and drop the 250 in that. Maybe doing some work to reduce the overall frame size to something more compact. Oh, there is so much to think about.

I'd love to see Ducati remake this and make it somewhat affordable. As much as I do love the I-4 250's and 400's that Duc was just pure awesomeness. |

I honestly have no clue why they discontinued 400's. Those are good sized bikes.

I love the idea of a 450 dirt/enduro bike turned street bike. Saw this a while back and had the same thoughts as you.

can't remember where I read about this, but if I had just a extra cash hanging around it would be an awesome project. however - for the cost you could just buy a used 600 supersport

I think a 400 would be a cool little bike. Not sure if I would get one (may have over the 250, but since i have the 250 already now), but still would be a nice small bike.

I'm sure it has something to do with emissions and I bet the 400cc road bike would need the same level as the 600+ bikes which would drive the price far too high. This is probably why we don't see 400 class machines, I bet the price difference between the 400 and the 600 is almost nothing, especially if you put in decent suspension.
But I still think a Ninja 400 or GSXR400 would be great and provide a good bridge between beginner and experienced riders. Keep it to about 50 horsepower and could serve both people very nicely. Alternately... How far can you bore out and stroke the 250? I bet you can hit 40 horses if you increase the displacement up to 300cc. Add EFI and ram air intake and I bet 50 (at speed) would be within reach. After all the 600cc machines can grab more than 100 horses, so a 300cc should be able to grab 50 if you built it to the same level. |

If I could have found a decent project bike, it was going to happen. Need to convert to EFI to really make it happen. And since everyone around here was stupid with their pricing the option went away. Put in a Microsquirt with a 2.5 bar Manifold Absolute Pressure sensor and maybe a single butterfly throttle that feeds to a Y where the injectors are mounted. Out of tank fuel pump with internal regulater and new coils with built in drivers and program the sucker and run it. You might need to change the cams so that you no longer have the large overlap between exhaust valve closing and intake valve opening, no sense in blowing all that air/fuel out the exhaust valve.
Getting the throttle body and making the intake runners with injector seats and fuel rail is the hard part. |

Didn't they make that already? Oh yeah... Tada!! Mine dyno'd at 40hp at rear wheel exactly! Honda rated them at 45, but you'll never see that.

try south east united states, about 10 hours from michigan. Otherwise I'd be all over trying to get a Canadian import. Maybe some day the opportunity will present itself when I can afford it.
