Yamaha TZR50; 6 Speed, 50cc, 2 Stroke | RTW #024 🇳🇿

A fully faired bike using the same engine as plenty of other small 50cc, 6 speed manual Yamaha's - including the RZ50. Does it live up to expectations?

I had a Yamaha FDHJ or some such (we called it Yamaha SS) in 1977. 49cc and restricted to 40Km/h through air-intake and carburetor. New exhaust, air-intake and sprayhead in the carb made it go 75-80Km/h, depending on the rear sprocket. I had a smaller one and went 85Km/h. To go faster you needed a new cylinder with 5 wash-holes instead of the standard three. After that I had a Yamaha RD50 50cc/7HP which was considered a motorcycle (49cc was considered a moped and didn't need a driver's license and can be driven at 16, motorcycles at 18). The RD went 135Km/h stock. Too many 16-year olds got caught and the RD model was replaced with the RDM50 which was 49cc instead of 50cc. From there I went to a Honda 750 Four. That was a bit of a change. I may have some of the technical terms wrong as I translated off the cuff from Flemish. Cheerio. Greetings from Belgium. Zealand in Holland was once Belgian territory, so hey, we might be related.

My first bike was a 50cc 2 stroke. All I remember was shifting gears CONSTANTLY!

Man I just love these kinds of bikes, like they were made to just have fun with, not necessarily being the apex predator but just happily revving to the best it can. Love to see some more!

Yes another video where the helmet mic didn't work. Whoops! Here's a fully faired bike using the same engine as plenty of other small 50cc, 6 speed manual Yamaha's - including the RZ50. Does it live up to expectations?

This bike brings me so many memories. I had one in High school. I maxed out at 105 -110km/hr on a bit of a downhill. The bike was not standard thought, full exhaust and carb jetting done.

The engine is not actually a Yamaha design, it is a moto minarelli. These engines were installed by a few different bike manufacturers over the years because they are pretty decent and put out upto about 8hp or more when not restricted.
Yamaha may have restricted it electronically, however some of these had mechanical restrictions that are easily removed.
There might be a reducing ring in the expansion chamber and a plastic wedge in the reed block. Look at the 4 bolts that attach the intake manifold and reed block to the crankcase, if one of them is a shear bolt then it almost certainly has the plastic wedge restriction. Remove the expansion chamber and look down the open end closest to the cylinder, you should see the ring and be able to lever it or grind/drill it

the fun part is you dont need a reg or a licence to ride this bike and some mods can make this bike super fast.good videos man keep it up ;]

[oddvin]

I have one of these and i absolutely love it, ive replaced the cylinder with a 70cc. better exhaust, reed, carb. and removed absolutely all restrictions, so it easily revs way past 14 000 to around 18 000rpm.

In 1976 Had a 1973 Yamaha SS50 (Pre FS1E) Great bikes and fun times here in the UK. Paid £165. Worth about £5000 now. Wish i had kept it....

[nitrorory]

I had the later version of this for a few years. There’s vids of it on my channel. It was great fun, especially with 70cc kit.
That one looks in lovely condition!

i remember turning 13 in 1982 and getting my first 2 stroke dirt-bike. i was hooked on anything 2 stroked from then on. from the sound to the smell. i appreciate the video thank u. P.S. u know those turbo'd 2 strokes that don't even sound like their changing gears the RPMs are so high., lol

I've got a 2005 aprilia RS 50, same AM6 engines as the later model of these, if I recall. With a basic head/barrel/piston/carb kit and an arrow exhaust. It hits the power at 7, 000rpm and revs through to 12 grand and it'll do 71mph flat out. The more expensive 70 kits and a bit of porting work will make them go even quicker. The 90s and 2000s were an amazing time for the small engines 2 strokes. Fantastic looking, sounding and smelling race replica bikes. The TZR 50 is no exception. She's a beauty!

Thanks from a first time viewer and new subscriber. I love little motorcycles!

I had a Kawasaki AR50 when I was 16 in 1995 (legal learner limit for 16 years olds in the UK) it was a nice 2stroke that my dad tuned up so it would do around 60mph. I remember feeling like a legend on it, I would've done anything for one of these one of my mates had rich parents and had an Aprillia RS50 a year later I turned 17 so could have a 125cc right in the middle of the 2 stroke heyday of NSR, TZR. RGV, RS to name but a few I had an NSR that would easily top 100mph then we passed our tests and it was on to 250 2strokes or 400 4 cylinder bikes happy days. Sorry sent on a ramble there..

[erikdikkers]

Had a Yamaha FS1 in the 80s. Z1 cilinder, 16mm carb and raceexhaust. 100 km/h at 12000 rpm. I loved it.

[firebladehonda]

i had it at 1995 120 top speed then i made it 125cc all the motor to this bike.you made me remember my youth

[davieheartattack]

I had a 2000 Aprilia rs50. It had a restriction in the expansion chamber. After cutting it out, it did 68mph. Used to beat all my mates on thier scooters. Loved it. Have a 200hp Honda fireblade now though that just sits in the garage gathering dust. I'll ride it again in the summer

[lacxys]

i had a 2 stroke 49cc yamaha tzr i switched the cdi and exhaust and i had no rev limiter after that and it went from 40-50 kmh to 95-100 kmh

[jacksondaniels]

A Yamaha Banshee 350 engine would make this thing straight crazy! While in the Navy during the early 90’s we made port calls to Japan. I saw these things all over the place. The Honda NSR was really popular as well. They sat out on the streets by the dozens.
