Building World's First 600cc 2 Stroke Dirt Bike!

[@lloydwilliams-nj2hl]

No music man .explaining wat ur doing an all the ins an outs is wat we want to hear keep up the mint build

[@kyledammann4284]

You two have good chemistry. Your videos keep getting better. When you have that, the sky is the limit. Keep up the good work.

[@999lazer]

Thanks Kyle 👍

[@crs583]

i agree music is annoying loud, had to adjust volume up and down a dozen time, it takes away quality from a good video , just turn it down by half

[@mbrad2669]

Or totally off...

[@jLkm897]

I thought about buying Panthera 600cc this year but decided not to yet because nobody had tried it yet. It is perfect size big bore 2-stroke for racing. Not too long stroke like Maico 700cc so it should rev higher. Nice to see you trying it so i can decide if i buy it too.

[@jlo13800]

Maico is 685 and it's pretty long stroke! huge torque though.

[@johnwalker194]

The pipe reminds me of watching big bore quads and two stroke buggies at half dirt/half loose road supermoto/rallycross meetings years back ! Big two strokes are cool 😎 5:46

[@davidhinton808]

I noticed that Sean checked to see the front wheel cleared that big expansion chamber when the forks were compressed, good thinking! It will be interesting to see if the 250 air intake will provide enough air for the 600cc engine at higher revs. Look forward to the next one👍

[@999lazer]

Thanks for watching David

[@The_Snowbike_Channel]

When you guys are done testing it as a “MX” bike, send that thing over to Alaska and I’ll put a Timbersled kit on it and race it at the hill climbs in April.

[@kenlares4769]

You know we'd love to see it at the Valdez Mountain Man Hillclimbs!

[@robertstultz6664]

Not the first 600cc to be made. But the first bad ass production from Pantera....yes. fuel injection. Yes. Big two stokes have been made for a long time...made in the hillclimbers. For the 0 to 700cc classes

You two seems to be a great team together. The frame looked just amazing! I did not hear is it the original rads, do they manage to cool the engine? Can't wait for the next episod.

[@999lazer]

Thanks Thomas, in this video it has the standard KTM rads fitted, but we are having some hardcore racing radiators tailor made for the bike. You will see them in the next episode hopefully :)

[@andrewmoylan6295]

G'day Max, this bike will be wicked, man, love the frame factory look, same as my fmf fatty pipe on my ktm 300 exc, might want to consider stiffer springs back and rear for the power this beast will deliver.Awesome work Sean and Max. 2 strokes forever.

"BRUAHH "👣👍🇱🇷, FROM NORTHERN CALIFORNIA WE DIG YOUR VIDEOS!!!! GOT MY HANDS FULL, HARVEST MOON AND ALL........... PLEASE DON'T USE 250 RADIATORS TO COOL TO 600 CC MONSTER. 🙏 PLEASE........ I grew up in the Coachella valley. (Indio) I'm the guy with the desert sled. 81 465 chassis from a YZ. Stuck in a 77 RD-400 engine. Voila Gonzo's desert sled!!! 👣👍🇱🇷 Anyway just wanted to say how much we enjoyed all this. We are the last of the premixers. Really enjoyed this all the way through!!! 👍🇱🇷 I was using an air-cooled engine it helps. Riding in the desert cooling is, priority. Thermal California, is the second hottest place in the United States. Death valley being the first. I'm thinking TZ 250 radiators, light and ment to cool a Grand Prix engine.

[@dr.hugog.hackenbush9443]

Airbox volume is going to be critical with this build. With it gulping up 600cc of air with every intake stroke, I'd personally fill every available open spot with either airbox or airbox inlet to have a minimum capacity of 2000+cc

[@mandrakejake]

I agree but to be a pedantic engineer, it won't be exactly 600cc per stroke, it'll be 600 * the volumetric efficiency, which varies depending on harmonics of the system. It can actually be above 100% (over 600cc per stroke) or substantially less.

[@KennethGerecke-k8w]

With a monster single cylinder like this, a restrictive air box may smooth out the powerband

[@adamwindle2572]

It will breath fine with the stock airbox...

[@adamwindle2572]

It will breathe just fine on the stock airbox.

[@dr.hugog.hackenbush9443]

​@@KennethGerecke-k8wBig bore 2-strokes generally usually have a pretty mellow, but torquey power character. They arent high strung and peaky, say like a 125 would be. So anything used to dampen the power is just wasting money on a 600cc engine.

[@ОктайМехмедов]

👍👍👍

[@mandrakejake]

When's my test ride then Max? 😊

[@adamwindle2572]

Love your videos mate. There has however been 600cc stroked KX's and CR's for donkeys years. Sidecarcross lads been at it for nearly 40 years. KTM even built a 550 which gets over 600cc easily. There used to be a 600cc Liger kit for CR's aswell. Think it's on youtube.
