-- YZ450GP Road Racer

Have you ever wanted to get into road racing but were put off by the high cost and technical barriers?

Now there are no excuses.

The YZ450GP uses the YZ450F MX bike as a platform and is easily affordable at just $16,625 inc GST.

The bike qualifies to race in the newly formed GP450 class that is rapidly becoming popular around the globe. This entry level class makes use of relatively inexpensive MX bikes that are available from nearly every manufacturer. These models are lightly modified to become genuine road racers that are capable of similar lap times as 125GP bikes at most circuits.

Yamaha Racing Developments (YRD) boss John Redding's goal is to attract newcomers to road racing by offering a fun and affordable entry level race bike. "The 450GP class is aimed at encouraging newcomers to the sport. With the help of Yamaha Motor Australia, the RRP of the YZ450GP machine is subsidised to help competitors enter this new and exciting race class. Plus if racers are serious about competing and have an existing YZ450F, we can supply kits for them to build themselves," adds Redding.

YRD is offering for sale a limited quantity of ready to ride 2013 YZ450GPs fitted with the road race kit as shown in the above photo. All the MX componentry removed from the new YZ450F 2013 donor bike is included.

Retrofitting the MX gear is possible at any time because the GP kit does not require any permanent modifications to install.

The race kit that transforms an MX bike into a road racer

The kit comprises:

Marzocchi 43mm USD forks (fitted with fully adjustable MUPO racing cartridge kit and springs)
Modified shock
Triple clamps, handlebars, footrests, brake pedal and gear shifter
Cast alloy 17in wheels
Dunlop production racing tyres Front: 120/70ZR17 D211 GP-A Med-Soft Rear: 150/60ZR17 D209 KP 523 Med-Soft
Full fibreglass road race bodywork kit (in white gelcoat – not painted) with mounting brackets
Brembo front brake assembly
Tacho/laptimer
Rear stand pickups
Each YZ450GP is supplied built up ready to ride with a selection of 14, 15 and 16 tooth front sprockets.

Cost including GST ex YRD in Melbourne is $16,625.00.

Please forward all enquiries to John Redding at YRD on yrd@bigpond.com or 0438 105 303

Looks mint................but at $21k NZ without delivery I can't see too many newcomers rushing out to get one.

i got that model yzf at home think it would look cool with that kit on it

[lostinflyz]

The YRD kit being sold in aussie is just the Beon Automotive kit (450gp.com). It is rather expensive, but does have lots of mods and is a straight bolt up job.

There are much cheaper equally effective methods of doing similar mods, but do require more hands on work/machining. i'd love to build one or help out to get a couple underway, i have 90% of the bits you would need (incl the fairings shown on the 450/YRD/Beon kit - they are essentially universal fairings with bracket kits) and a decent grasp of the knowledge. Send me a PM!!!

After reading this thread that i stumbled upon lead me to do some research!

http://www.motoconcepts.com.au/2012/07/fx-450gp-class/

These rules make perfect sense. This concept makes perfect sense. This class is working in other parts of globe. I checked the results in the auzzie series and the 450 mxers converts are holding there own and getting results. Road racers, don't fear the dirt bike. Iv'e thrashed a motard round the tracks of the South island harder than most, never had a mechanical fault yet! They are that bullet proof if left standard which I have done.

Going to save some $$$, build one of these things. Would prefer the kit as it seems to be proven. Seems to me that it needs to be at least given a proper chance so any handling issues can be sorted with affordable mods developed. Kiwis are very clever people.

Keep an open mind people. I believe this may eventually happen weather we like it or not. We don't want to get left behind here in NZ and give a future races a miss opportunity to race in a proper controlled class. As far as controlling rules go, people will soon learn not to mod the motors, they are already highly strung and trying to make em go faster people will just loose there reliability and a national series would govern itself real quick!

Now in saying that, I know nothing about nothing, but I do believe if nothings is done, we will get the same result, diminshing younger riders. These things have the wank factor, they can look at it in there lowered hiace van and think they are pro racers.

Thats my piece. Happy days.

Jeeeesus Johnny, who hijacked your log-in details ?

[Johnnyc34]

I'm not sure, but some one who has a few more clues than me! Haha, was all me my friend. More I think about it the more I want to make it happen.

Have I ever put you crook ?

Might have more joy with a super-mono class. Everything open but has to be a single and run on pump gas. But that is basically F3 anyway. Would live to build one. Its on the list. from what i have seen of the dirt bike conversions they cost lots and don't go as good as say an NSR MC21 with a 450 500 whatever. Much cheaper to bug an engine in a roller.

Oh and my bike almost done. Will be riding it this weekend. A dirt engine would fit really easy. But I like the little engines so a 250 would be my choice.

I agree here. Back in South Africa we had a class called Super Single. Basically the only rule was single cylinder 4 stroke 500cc or 2 stroke 250cc. You could use whatever rolling chassis you wanted. The class was very well supported and a lot of fun. What made it quite cheap was that there was an engineer that build frames/swingarm from steel that fitted a xl/xr/xt motors. He sold these at a very reasonable price. So you ended up building a nice handling racer for not to much.

Another, very successful class were a Production class of either a 250cc 2 stroke (NSR/TZR/RGV) or 4 stroke 400cc (CBR/ZXR/GSXR/FZR/etc) which was so successful you had to qualify to make the start grid.

All sounds like good 'ol F3 .............

After reading more about the Aussie FX-450GP class, I'm starting to like the idea.

I agree that most of the kit needed should be easily sourced or found 2nd hand. The hard parts would be Triple clamp for getting the right rake and trail. The only thing that bothers me is the rule around not being able to change the rear suspension linkage or shock. When looking at the Aussie FX-450GP race bikes in the pics, you can physically see the swing arm angle is all wrong. Those things are not going to turn!!!!

aaah, the theory fairy has paid a visit !!!!! Agreed, the angle is not optimal by the latest standards - but experience has shown that they DO work, they DO turn. The limits are ONLY as a cost minimisation measure - limit the mods, limit the $'s. Its a piece of piss to find reasons NOT to try something - Kiwis have a history of making sub-optimal things work pretty bloody well - look at some of the bikes our hero's have kicked arse on in the past, not all have been "right" or the latest up-to-date technology - in fact most have been things others have tried and discarded as not suitable !!!!!!!!!!!

Completely agree there Budda. So what if they don't turn in 100% ! That is something that can be sorted as time goes on. Here is how I see it. SV650 took a few years to get developed. Every other class to a few years to get developed. Here we have a fleet of these bikes available nation wide. Anyone that says they are going bang and can't handle the revs....one word for you, FAK off! Well serviced and kept completely standard with change gearing and muffler change they are sweet as. I did 28 hours on my motard before I stripped it down. The engine was in perfect order, it spent a stack load of time pinned on the rev limiter at Teretonga. 28 hours was a heap of riding on the track. Over a year and half of riding it every month. Bottom to top end rebuild in parts appox retail $1000. Bit more for your labour if your not inclined to do it yourself. This is the future to get the bunny chases into our sport. There is a huge amount of 30 - 40 year old age group who's bones are getting tired of bouncing about over rocks and hills. There are hundreds of these 450cc bikes on the market at the moment. Any were from 3k - through to 14k. I don't see a massive amount cheap SV650 or EX250 ready to race. How ever I do see alot of MX bikes with the potential to be converted with ease. I really believe you would have a hole in your head to think badly of this concept. So what if a few people have been high sided overseas. Hows that the bikes fault? Last time I watched any form of racing I saw alot of bikes highside! So what if a few have gone bang and dumped some oil on the track.... I've see a lot of other bikes do that too! And I tell you what, my bet is they weren't standard engine, some muppet that wasn't skilled enough thought he would hot up his bike to beat the talanted rider with the stock engine in front of him!

There is way to much for this than against. I'm going to build one. It may take some time to pull the resources all togther but I am going to do it. Hope some others follow.

Lets face it, SV650's in both modded and ProTwin forms took over F3 - and THEY burst if not maintained !!!!!!!!!! and THEY have spit the odd pilot down the road too. All I'm saying is that, like JohnnyC, I see far more positives than negatives - the only thing stopping this from getting a head of steam is nay-sayers whose knowledge is mostly based on what they read on forums. The ones that HAVE been built already, here in UnZud, worked well with very little development ( and that is not a criticism )

EVERY Distributor has at LEAST one suitable model in their range, and TurdMe is chocka with suitable steeds, mainly destined to "win" their local trailride and terrorise beachgoers with no muffler, and turning Joe Public even further against US ALL - do the Sport a favour andconsider building one, if only to keep it out of the hands of the dickheads !!!!!!!!!!!!! And if it IS as bad as you think, sell it as a wrong-bike then !!!!!!!
