Ok, I was online looking for more motorcycle perversion and came across this www.450moto.com, and all of a sudden became inspired . Anyone think a 1125 frontend will bolt up? | ||

Thank you for posting that link. That was something that I was thinking about for a while as an affordable 4 stroke GP bike. | ||

Kinda odd the convergence of the new Mono GP movement and the emergence of a production 450cc dirt bike. Almost like it was planned. | ||

I think it is going to be a very popular conversion . Especially if it can be made street legal. | ||

Not hard to do. GT - JBOTDS! EZ  | ||

The Buell would probably make a better candidate as they'll most likely run a shorter wheelbase and tighter steering head angle, as has been the trend. Them things run a real conservative chassis geometry.
I'd disagree. Getting the suspension/geometry/weight distribution right and looking at all the small details it's not a task for an amateur IMO...just like all these Blast front end/wheel conversions that reportedly handle like crap. There's a lot of fabrication work, too. Subframe, bodywork brackets, rearsets, wheel/brake/sprocket spacers, swingarm/shock mods, custom sprockets, exhaust system, etc. It also doesn't appear like it'll have a tank/frame good to brace a leg against for cornering in a road race seat/peg/bar arrangement(if the picture that's been circulating has any accuracy). A dummy tank would probably have to be fabbed as well. There's a reason why nobody in the British Supermono series runs a stock 'crosser frame. (Message edited by Rick_a on September 22, 2007) | ||

All it takes is perseverance and study - I like the idea - a dedicated chassis is a better option - but if your really trying to do it from scratch - then your into serious money. GT - JBOTDS! EZ | ||

As a spec-style class I think it'd be cool... apparently once lowered they end up with fairly short wheelbases (Message edited by Rick_a on September 24, 2007) | ||

this is an existing class in Japan but then Honda in typical Honda fashion decided to build a GP Mono bike using a GP125 frame for a "factory rider" and spun it out of control....I remember the conversion Kits for order at the Tokyo motorcycle show. Keep it based on a stock chassis and I think it's fair and the factories will stay out. | ||

I believe they will only use the stock frame and swingarm,to keep it competitive. It also uses the stock tank ,it just has a cover on it. I think the only mods to the motor is a pipe and jet kit. | ||

The kits in japan were essentially wheels, body and a new front end | ||

Well, here's most of the answers: Re: Roland Sands CRF450X roadracer: We test it at the Streets of Willow! Options Options rsands Newbie Posts: 2 Registered: 09-20-2007 rsands Message 28 of 39 Viewed 83 times Questions answered. 1. Will they handle, doesn’t a motocross bike have completely different geometry ? 54” (1393mm) wheel base 22.9 degrees of rake 98mm trail 22.8”(580mm) swing arm length 250 lbs These numbers are nearly identical to a 250 GP bike. So yes it will handle. 2. How do they ride ? Isn’t a motocross bike built completely different than a road racer ? Will it flex ? I’ll let Kevin Schwantz answer this question. "Yes, they actually handle, turn and brake just as a road racer should, just a blast to ride." Added Kevin Schwantz, "Properly set up, tweaked and a 60 bhp lump, just a great way to start racing.” Ultra Stiff twin spar aluminum frame and swing arm are built for abuse, crashing and thrashing as anyone who’s ever cased a triple knows. In road race trim they do the same job and do it just as well. Do you think Bubba’s bike flexes ? 3. Will the motors live ? This seems to be the biggest issue and concern. They ride and race them daily on tracks across the country in many different levels of tune in not only motocross but also desert racing and flat track. If restricted to only make a certain amount of HP (55 to 60) it seems it wouldn’t be a problem to get them to live.  ...and my favorite of the four that've been built. | ||

I'm hoping a fifth one will be added. | ||

Barebones racing was doing conversions here for years and Tigcraft in England. Starting with the TZ or RS 125 and 250 chassis and spooning into it a Rotax 604cc (air cooled, SOHC, 4-valve) - made it a KILLER machine! Imaging shooting around on a bike putting out 70HP and weighing LESS than a 250GP bike!    | ||

The Dream Blast - lol - this is definitely the ideal ticket! GT - JBOTDS! EZ | ||

There is a fundamental difference between this new 450Motoproject and existing Supermono classes, and that is the retention of not just the stock MX frame but also subframe, swingarm and fuel tank. This reduces costs immediately compared to the latest generation of 'Minimono chassis from Tigcraft etc. It also makes it MUCH easier to convert an existing 'crosser to road race spec than it is to go down the bespoke chassis route. In addition to the parts being available in kit form shortly, Roland Sands is also working with Race Tech to get the stock MX suspension converted to road race use. This will of course reduce costs even more and will enable riders to use stock Supermoto wheels. The only doubt I have over the class is that it so far only includes the big 4 Japanese constructers, yet the 450 class is dominated by European brands such as KTM, Husqvarna and Husaberg to name but 3. Hopefully the forthcoming series will encompass these as well. The Suzuki 450 Moto prototype is the only one that was not built by Roland Sands, and actually shows what a home builder could achieve far better than the other 3 prototypes. It uses Suzuki RGV250 bodywork/seat/tank (just the shell I think). Rearsets are adapted from another Suzuki model. (Message edited by trojan on October 18, 2007) |
