 |
|
Simple question... has anyone replaced the original 4stroke in Suzuki RB50 with a stroker of any description?? Although mine has a couple of Takagawa tuning parts, it's still in need of some "go", and I'd prefer it had a ring-ting-ting soundtrack too!! Any help or guidance would be very welcome 
The Skoal Baby paint job can come later!!

It was done by the Suzuki factory itself; search for "Solifer-R" 
http://www.suzukicycles.org/Solifer-Suzuki/Solifer-Suzuki-R.shtml
The engine was based on the usual TS50ER, meaning a RM80 would fit

The Solifer was even slower than the 4-stroke RB50. 
You want to keep it Suzuki ideally, look at the baby MX's that kids race. Is there a bike autojumble near you ? Always lots of that sort of stuff at my local one.
Aircooled means you don't need to squeeze a radiator in somewhere.
But my local Suzuki-pervert (who you know ) is able to make anything fit anything else if you get stuck. |

Would a TS125 fit? This could have over 15hp with a bit of a fettle
RB50
TS125

Well Darin, in anticipation of your RB one day being faster than mine, you've now got me poking round Japanese Monkey-bike sites looking for tuning parts for mine.
Project "tuRBo" starts here... |

You coukd also look into using a 1980 TS250 with a tuning kit taking it from 23hp std to over 30 reliable hp
Engine looks slightly bigger than 125/185 though..?
Decisions decisions decisions

 I really like the idea of an RM80 motor, and having ridden my mates old RM100 when we were 15/16 (which went like STINK!) - that sounds like the right answer... and a bloody scary one!!
I'll have to do some measuring, but after a quick look at specs (14/15bhp @ 11000rpm) it sounds perfect

Yeah definitely want to keep it 'Suzuki' and aircooled as I don't want to have to faff with rads and water pipes.
I might have a chat with your perv too

Cheers Shaun, worth a look if the RM80 doesn't work for any reason

Couldn't agree more fletch - I guarantee you won't be seeing any WC on it
