Got up to 55 Mph on my Aprilia RS 50 today.

I bought an Aprilia RS 50 (50cc racing motorcycle) on memorial day of this year. After several months of trying to get it licensed and many many setbacks, I finally got it titled and started riding it to and from school. Today I went to Wal-Mart to return a movie and was able to get it up to 55 on flat ground. This is pretty impressive for a 50cc bike, and I felt like it had more juice in it (although not a lot). I got the same turbo used on the world's fastest 50cc and may design some cad parts to get CNCd to make it fit.

Anyway, I'm pretty pumped. It's a fun little full-sized bike. It's perfect for in town.

55mph in town? tsk. tsk.

Shoulda been aiming for 88 miles man, everyone knows thats the magic speed.

The speed limit on that road is 45, so yeah I was pushing it a little, but Wal-Mart is on the skirts and it wasn't busy.

There's a lot of BS about the speed of the RS 50. Lots of people say 100mph stock. That's crap. You'll get around 40-45 stock, 50-60 de-restricted. The guy I bought it from said he got it up to 65 on a slight downhill.

If I add the turbo I should be able to add 2-6hp to the thing. A new head and cylinder with a higher compression ratio would add more power as well. A new carb would help as well as carbon reeds and a new exhaust. That said, the first thing I want to do is paint it with glow in the dark paint and retro-reflective clear. Maybe add some EL wire in tasteful locations.

I'll put pics up tomorrow.

when you turbo it, take a picture. lol I wanna see your boosted rs50! haha

[SXRguyinMA]

but if you turbo it you want to keep the compression down. too much and it'll deto, and that leads to all sortsa problems

Nice! The max on the 250 is about 105mpg...


Downhill....


Crouched...


With a tailwind...

Most I've gone is 95, and that was weaving through traffic on the interstate. I definitely want to see pics though!

Nice!

I love the Aprilia's... A buddy of mine bought a new one a while back. It was originally intended as a race bike and it took him over a year to get it street legal enough to get it registered. I will have to ask him what model he got...

My sporty was doing 85 @ 3500rpm on the way to work this morning. I have only had it to 90 since I am still supposed to be gentle to this engine until 4000 miles (then I can dyno it). I looked into taking it to the track once it is dyno'd, but I would have to spend a couple of weeks getting it track ready. Not sure I am going to spend that time right now.

and yes, PICTURES MAN PICTURES!

Interesting, but I gotta ask why you went with the 50? Is that to get around needing a license? I'm just wondering because with all you're planning on doing to it, I feel like, get the kind of power you want, it would be a lot cheaper to just have gotten a bigger bike.

Heh... mine does 80mph @ 10krpm... 90@ 11k
