While most everyone else has moved on to the land of 4 strokes, there’s a group of intrepid engineers and builders in Australia devoted to the idea of building a 500cc 2 cylinder 2 stroke motorcycle, starting with the Aprilia RS250 chassis and installing their own highly engineered 2 stroke powerplant.

Grand Prix Engineer Wayne “Wobbly” Wright who has a 30 year career building GP engines and pipes went to work on the engine and the finished piece puts out 112 horsepower and 60 foot pounds of torque. Mounted in a bike weighing 286 pounds total and having the power delivery you would expect from a 2 stroke gives you a bike that one might call entertaining.

The idea here is to bring 2 stroke technology up to the best that can be built right now and place it in a modern frame and suspension package, a combination you can’t buy in your neighborhood showroom.

The company the group formed is called the Two Stroke Shop, and besides many other parts for the 2 stroke fanatic, they offer not only complete RS 500 motorcycles but also the engines alone or kits to adapt your own RS250 to accept their engine.

There are no prices on the site, expensive I’m sure, but what they offer seems somewhat unique. It’s an extremely interesting setup and just the thing to surprise the heck out of your average GSX-R pilot. I like it.

You buying?

Nice.

Yeah that might ruin me forever...Like a Jessica Alba/ Jessica Biel sandwich, how much can your brain stand?:drool:

You sick bastard.

that looks pretty badass to me. I"ll take 5 of em!

according to their specs that comes to 2.56 lbs per hp. Now I was just sitting here trying to come up with a poor boy option...I know a typical middle weight RR can be tuned into 118 hp and track prepped to 370 some odd pounds or 3.14 lbs per hp.

Someone help me find a way to get a cheapo used 600 down to 300 lbs...or cheap durable engine mods to get 145 hp in a 370 lbs chassis.

Of course there is no way to duplicate the light and responsive nature of a bike weighig just 286 lbs. Or the responsiveness of a tuned 500 cc 2 stroke so I am probably better off spending my time wanking to old Jessica Biel photos huh:idk:

Here comes the flames... um can't you get a GSXR1000 down to about 370 lbs? Hp is a no brainer and I get about 85 ft/lbs of torque from mine with a slip on and PCIII. Hey better yet,what about the 750? Seriously,once you remove all the "street gear",sub frame,etc wouldn't that meet your criteria? Hey,I used to ride a RZ350 back in the day and I understand what a 2-stroke can bring to the table but....for power band,reliability,tune-ability,etc don't 4-strokes beat them hands down?

[smileyman]

I had some seat time on a TZ 250 Tigger and I don't think I can make a 370 lb bike handle like a 286 or whatever bike does...90 lbs is an incredible difference in braking and turning. I think even the AMA superbikes weigh more than 370 lbs. And then their is the difference in engine/crankshaft mass...Just no way to replicate it on a budget.

On the other hand your right, 4 strokes are so much better with maintenance there isn't a comparison at all. They are pretty great.

So on an ulimited budget, sure we build a bare bones titanium framed GSXR1000 with ultra light forks and wheels. Everything lightened. Or we spend the same amount and buy this 500...:idk:

Oh for sure! I don't think we can get a 600 down to 286 lbs but it would be fun to try!!! I know you are right,I was thinking in terms of power to weight. Corner speed is another story but again the new 800s are "too fast in the corners" according to Dorna. :idk: I was thinking about your budget and what is somewhat possible.

Note: let's use carbon fiber for the frame on our imaginary GSXR!:drool::drool::drool: besides I think Ti is too stiff...

On my budget I was thinking bolting an old ninja 250 motor to my mountain bike!

Good one! Hey we could always get pocket rockets and race in parking lots! Better yet,since I'm so scared,let's get remote control bikes and race those! Hey wait do you have X-Box 360?......:whistle:

[smileyman]

I wish I had an Xbox...I still have the original Playstation. and not the PS2 either. I do have 2 WSBK games and a dirt bike/streetbike simulation for it though. And get this, I have a SEGA Genesis with Kawaski Superbikes racing...Talk about low tech! But I still play them.

Jesus! Well,if you take all that um stuff to Gamestop they'll give you a few bucks towards a 360/ps3....

I still have been mine. Lets go! It hasn't been started in well over a year but Ill get it ready with notice.

hey I think someone here will loan me one. do you have one of those cheap ones or a good one?

[jeeps84]

Cheap but not stock and fun as hell. I was paced doing 50mph. Never thought it would go that fast. Will hurt you quick too. My tail bone hurts just remembering a wheelie gone wrong on that lil bitch.

[Mr Lefty]

I'd love to get a pocket bike... how much did yours run jeeps?

[Ducati Diva]

Jeeps said bout $250-$300 new but you can find it cheaper used.

[Mr Lefty]

damn... I may just have to get one... wonder if they ship to Korea :lol:

[Ducati Diva]

damn... I may just have to get one... wonder if they ship to Korea :lol:

you could prob find one over there but they will ship anything if you got the money.

looks like me sitting on Kat's bike :lol:

Sweet I'm on it!!!

? your on what?:idk:

Sorry bad quote,I'm gonna get one so we can have a NC pocket rocket race.

ahh... I was like wait... I missed something

[jeeps84]

Their use to be 5 to 10 of us any given Sunday in the school parking lot F'n around on these things. Lots of rash and even more fun. The fad just played itself out. Just a few even still have'em now and nobody rides sept in driveway any more.

[smileyman]

I see some folks (students) here in Fayetteville commuting around town on these things...The larger pocket bikes even though they will run 50 don't look safe or legal as they dont have any lights, signals, or mirrors...:idk:

They aren't but some towns let it slide.

Don't bring them shits to FL with those tough new laws. :willy:

and what's more it's in 2 stroke form... so not only do you get to ride an amazingly powerful bike... but at any given corner you could be sky diving! :lol:

My little rocket weighs 321 #'s with all fluids but gas as it sits right now. It puts out about 84 hp at the crank. (904 stock, 42mm keihins, Moto Corse full system). If I go with the FBF big bore kit :

BF 944cc big bore Kit
12.1 pistons
Titanium connecting rods
FBF power crank
FBF ported cylinder heads
Oversized valves
Lightweight flywheel

If Ferracci installs it, they guarantee 100 hp AT THE REAR WHEEL.

Lesse; if I ditch the Antara mags and go with Dymag CF's, I'll save a whopping 24 lbs alone. (http://www.oncycles.com/dymag/carbon.asp). The aluminum flywheel saves almost 6 lbs., Ti clipons, pegs, CF custom bodywork for the top and side panels, and mebbe Ti triples and lighter weight rotors than the big Brembos, I should be able to shave another 5-8 lbs....that should put me in the 285-9 range; it'll make more power everywhere but most of it goes to the top end, it won't have the all-or-nothing lightswitch powerband of a highly tuned two-stroke......
