i don't want to shell out the cost of a dt bud, i have enough money in my 172 and i have my 4 poke daily commuter

iv always fancied an sm and these look like great fun to fiddle with.......and i really miss the sound and smell haha

Hey mate, where I'm from (Finland) they are both really popular bikes, but if i were to choose, I'd get a Rieju; It has the same engine as the 50cc Yamaha DTs (Minarelli) and better electronics than the Derbi, and in general, much higher build quality. If you have any more questions about 50cc peds and some tuning tips for them, I'm your guy 

The 125 is a 4 poke so as much go as my honda msx ie none haha

The derbi I believe runs the same Yamaha engine as the rieju, the aprilia and the CPI, mineralli lump

The dt I realise is a better bike. But the ones local too me are 1600 odd

I'm looking at 800 for a 58 reg derbi. It's a toy not a daily use bike, and it's just to pass the summer as my gilera 172 is taking longer then expected and won't be ready for the sun this year!!

Karaikun, I'm comfy with 2 stroke tubing having built a few 172s in my time and fitted bigger carbs etc. the derbi draws me in as it sounds great and it's a big bike. Good fun for ripping about on and maybe some trail riding, all be it gentle riding 8-)

The DT50 has a Minarelli AM6 engine same as the Rieju. The Derbi, Aprilia and other bikes now owned by Piaggio have the "worse" Rabasa engine. I'm not saying every Rabasa engined bike is bad per se, but the one I owned (Aprilia SX50), was terrible with a lot of gearbox and electrical issues and it seized at a bit over 3 000 km. Lot of jokes made about the quality of the Derbis/Aprilias here in Finland.

ay? its a 2 stroke lol of course it has a power band of sorts

probably a red one with sparkles P-)

the dt shouldn't just go bam unless ur pv is pinned, the idea of a power valve allows decent bottom end until peak rpms are reached i know seanftw's dt certainly didn't pull anything like my rs 125 fp when that opened up the pv at 8k haha

now with a 50 their is no pv so infact the power band should feel greater as it will do from boggy to peak power

the derbi i test rode had a real snappy power band which was a nice feeling.

4 strokes may create power through a set rpm range better but i know my 2 valve 4 poke air cooled honda i use daily is about as exciting at any rev range, i.e. its not haha

But the step from a 50 to a 125 is so big in power terms, might aswell get a 125, not really sure what your after here, theres nothing about a 50 that outweighs the 125 2 smoker, isit the lack of power you prefer?

And i dont mean literally bam full power lol, but you know what i mean it hits that certain rpm range and it starts picking up on the power very quickly

Yeh im thinking more like offroad 4strokes, mx and that not commuters

Always comes down to money ay, might aswell get an 85 big wheel and get it road llegal! Ha na, frame to small

Well whatever floats your boat matey, hope you haven't got L plates though...you will look like a 16 year old chavvy lol

How do they lift those 50's so easy

Yeh and look like a d**k in the proccess lol

£250 later i picked up this

and after a little tickle with the spark plug and some fresh fuel it fired up and ticked away nicely

won some forks on ebay for £32 posted to replace the bent ones which will hopefully fit

few other little bits to do but in fairness after the forks it should be almost mot worthy
