I was Robbie's mechanic back in '89 when he was riding a John Lassak prepared Aprilla Rotax powered 250 gp bike- Robbie was a JOY to work with- we ended up finishing 3rd in the AMA 250 cc championship that year - don't be fooled by Robbie's mild mannerisms - when that helmet was strapped on, you had better be ready for a fight - unbelievable talent

When Kenny did his annual fundraiser for wounded veterans in 2015 it was at the ranch in Hickman. Inside his shop were some of these Proton GP bikes and shelves full of parts for them, many still wrapped in plastic. It was pretty unreal to see all this cool stuff. KR quipped that there's a lot more to being a bike builder than having a hacksaw and a grinding wheel.

I started watching GP at the end of the 2 stroke era..... Saw them life, the noise, the smell...... No electronic aids, like a wild horse. Glorious days Thanks for the video

2 strokes are Unbelievable bikes , had TZR250 reverse cylinder 3MA , it's was amazing , the Smell and Noise can not be beat

wow just wow, I absolutely love the GP 500cc two strokes mainly from the USD fork bikes onwards, that triple engine is a unique design that's for sure, kind of like a semi factory engine, between the v twin privateer and the V4 factory bikes, and it is totally unheard of to own a set of factory GP bikes with all the spares, so awesome.

I made pistons from forged pre-forms for these engines in the late 90's. The client was 'Tom Walkinshaw Racing'. There were a few minor design changes with skirt vents and crown shapes. I rescued a few of these pistons from the scrap bin when I was made redundant. If you reply to this comment with some contact details you may have them.

2stroke...3cyl...185whp...115kg...hell on 2wheels...my dream..

Back in the late 70s and 80s was BIG into the triple 2 strokes ..had them ALL at one time or another up to the kawi 900 ..man those were the days .folks thanks for the flash back

Kenny Roberts the legend

its really great 500cc two stroke, it almost beat 990cc four stroke at 2002 MotoGP

That would be great to see , Kenny Roberts running one on the track !!!

185hp + 120 kg its a scary bike... hebat proton kr

Thankyou ever so much for sharing..what an artform!!

That two stroke sound is the best

tu fully modenas, lepas modenas tarik diri, proton join. then last race australia 1st pole, race dapat no 10.pastu xpakai lagi sbb motogp switch 500cc to 1000cc

I'm not all the way thru the video yet but how dare you rob us in the US the ear candy of a two stroke with music. We rarely ever get to hear a racing two stroke!

Robbie Peterson, met you and Rich Oliver ( talked to your mechanics outside the bathroom later ) at Road Atlanta years ago at The Grand Nationals. You guys were/ had been racing Yamaha 250 two-strokes, but that day you guys had the first Malborough Yamaha 500 c.c. two stroke, the first time I had seen, possibly touched the bike of legends. Great day for me. My second visit to South Africa, went to the South African G.P., took my dad who was living in Capetown via Swaziland, stayed small guest house with two teams, got pit pass from Shell Advance Honda boss. Quite the time! Gary McCoy won.

Back when it took more than just money to win..and massive skills n balls..were a MUST..today we'll you all KNOW..back then it took everyone to make it happen ..

the beast from south east asia

History at it's best.

Priceless 👍👍

Excellent video guys - thank you for posting!

I remember the days of KR Protons either before or after Carl Fogarty's team and his custom bikes.

Would love Dave Peterson to watch this again with Subtitles on. Hilarious! Shows you what he wanted to say!

Very super dudes, loverly video and omg proton KR 500

Hi Michael McCabe. Thank you for your comment. I don't think we have ever met? Dave Petersen

anak dia suzuki biru yg satu zaman dgn mick doohan, max biaggi... itu je yg ak ingat masa sekolah rendah dl... moto merah, biru, oren

Wonder how much he paid for them... I am sure KR didn’t give them away. He has option to ride anytime he wants, most likely also to buy them back or approve of a sale to someone else.

*Cracking Sound at **6:10** Wonderful*

I’m sure he paid a pretty penny for those bikes,and all the spares too! 🙀

15 tahun rehat woih. Epic betul

I'm wishing these Proton bike for sale on the road. I'm sure lots of people wanna buy especially Malaysian people. Why not give it a try.

The so-called music is just annoying in this movie clip.

Saya bangga jadi rakyat malaysia 💖 i love proton. Pro

Ada jugak sejarah proton kr3 yg nk diceritakan...

Thanks for sharing Very interesting 👍👍

Interesting video, shame that it has music throughout the entire video.

Hard to believe this has so few views. KZfaq viewers are an odd lot. I am not much of a "personalities" person, but a "science fair" type. Thanks for the wonderful content. Nuts and bolts > dumb ego stroking.

Jeremy McWilliams used to get a good time out of it qualified on pole at Phillip island in 2002 got swamped of the four strokes of the line but one lap pace in his own it was rapid

Cosworth developed a special metal matrix alloy for this project which was based on 2618 aluminium with increased silicon to limit expansion. We called it 4X alloy. I recall there were 3 minor changes with transfer vents and crown shapes before the project ended. I rescued a few discarded pistons which I still have today. However they are bare without ring or pin. Peter Cutler

This is pretty cool... I literally discovered motorcycle racing 3 years ago, and this KR3 bike just yesterday... Does this bike still come out to play in public view ?

Rare collection

Proton Malaysia

They are dearly missed in motogp

Yehaaa 🇲🇾

Yeah two stroke are fun for the highly skill moto racer...but for the average an even a good rider who not used to that power hit point lift the front an turn the corner on the back wheel its no surprise kenny elected to work the power so it was more friendly ...i always wonder how the heck with all that front end lifting kick of the nsr or yzr how they road in heavy wet conditions...so its no shock the king made it smooth all the way thru....one thing about the japanese their riding an roads where very different an obvisiouly their motorcycle philosphy...of what they want to build too....as a serious racer i can understand KR i raced motocross for 14 years...an most of the bikes were not race friendly motors had to be done suspension overhauled or u get spit off an that was bike wide...now things are much different...all street bikes are design around the honda CBR...a razor blade handling type Road racer.....turns beautiful but not as stable...peace that is really cool the proton...i know the oil gas era was banned by european emissions not sure if racing was first...to do it but thanks for the look....very nice....

Funny @1:12 As you can see the kr3 simply steam's past the rest of the bike ,No kidding Batman ,the Rest of the bikes are 125cc & up old relecks the Robert's Former bike was a early 90's Generic Low grade Work's bike that couldn't touch the factory bikes of Honda, Yamaha, Suzuki , & in that order.

nice ride ! What two stroke oil you running ? at 50;1 it must be good..... my old race days I ran PolyOxide, zero carbon.......no failures, like most good things it went away .....

Wow menarik...jenama proton

Dalam sejarahnya motor ini memakai mesin dari KTM,LOTUS, APRILLIA dan HONDA. Proton hanyalah sebagai sponsor saja di motor ini hanya mendanai, makanya motornya di kasih nama proton, sebelum proton motor ini di sponsori modenas dan karena modenas kesulitan finansial akhirnya pendanaan di ambil alih oleh proton. Contohnya Sama seperti saat ini Petronas yg mensponsori tim di MotoGP dan f1.

Fantastic video!

Proton mesti join balik

Very nice,but the bike was neither designed by Kenny Roberts nor by Sponsor Proton.Engine designed and built in England by TWR and the frame built by French company FTR. Sorry to say but no significant technical engagement by Malaysian company Proton. That might have been the problem because TWR had no 2 stroke experience. Why did KR choose TWR will remain a mystery to me.German Sepp Schlögel or Swiss engineering company Suter would have been better choice.

The owner digby nesbitt passed away due to covid 3 years ago

The nsr 500 had 190bhp with 4 cylinders the v-twin aprilia had 140bhp this probably had 170bhp roughly mega bike

Who many horsepower, 185? Realy?

i like 2 stroke..

The KR3-bikes were first used in '96 or '97 though, but at least far before the 4-strokes were introduced in 2002. Get your homework sorted!!!

Proton 🇲🇾

Last bike from Malaysian team.

What's with your foot placement? You must go through a LOT of boots!

mcWilliams qualified on pole, I think in Australia?

Kalau ada minta pihak proton membuat motorsikal jenama proton mcm honda, suzuki, bmw dan naza

That's one lucky dude that's the closest you'll get to owning a works gp bike as yamaha/honda/Suzuki do not sell their gp bikes 2 strokes not dearly missed

I always routed for the Chaps who competed on these bikes, Kenny Roberts should have stolen a cylinder from Suzuki and defected to Italy with it. .

Mr Kenny Robert, Im willing to take care your machine n parts to let you rest in peace.

it was the, 'Modenus KR3' until Proton bought the company in 2001, and rebadged it the Proton KR3.

Wow,next

Wow

Nice proton Malaysia

bloody muzak!

jual murah dimalaysia...boleh laku...org malaysia jiwa kelajuan #jbstyle 😂

I really want to watch someone make a video 500cc 2 stroke motogp battle with today modern motogp at same time same circuit not comparison from seperate videos...please im desperate!!!!!!!!!!!!!!!!!!!!!!

Great video,awesome bike. i played gp500 pc game and came here to find info.

Sepatut nya proton keluarkan juga motorsikal..bukan hanya kereta.

Malaysian proud

fuckin music -.-

Recall this machine was real thirsty for fuel on the grid .......

Very interesting video but the music is just far toooo loud and no need for it. Plus Mr Mcwilliams is Northern Irish and not Irish.... There is a difference....

Rare, well made in malaysia, this motorcycle so hard to find in malaysia 😭

Kuat minyak tapi pecutan luarbiasa

I wonder what he paid for the 3 of them?

MMMmmm leaded 110 octane twostroke fuel i can smell it from here

LoL, yep, love 2 strokes but they're thirsty. :)

i wish,im gona buy this bike someday.

@gengtayarbesar

Very interesting guys...... except for the 'BACK GROUND MUSIC'!!!! way too intrusive though to be fair it is a modern scourge. Grrrr

Hidup RXZ

Music ruins another great video, would rather listen to the sound of the bike.

Shut up and let me hear the engine!

Is it using kick starting???

Proton bangkrappp

Good attempt by KR but this bikes never won anything, pity

Todays Bikers Wouldn't Have Clue What Its Like Riding A Two-Stroke I Only Had A 250A Suzuki. The RD Yamaha Was Faster And Looked Better. But I Could Leave Any Car Up Too 70mph No Problem Wish I Had It Now At 60 Years I Would Still Burn A Car Off Ha Ha kzfaq.info/get/bejne/ecWEjaRe386aiJc.html Arch Enemy But Best Mate's Barry And Kenny. Enjoy.
