RD 400 on eBAY. Don't like the bike or the price. But...

I'd like to know who makes the clutch slave cylinder they used for the hydraulic conversion.

Anybody recognize the part?

Gigabike.com swingarm is apparently thaigigabike.com for an SR400. A lot of cool billet parts. I think the rearsets probably came from here also but I can't read Thai. I didn't find the clutch slave here.

I've seen those, actually had one, it was garbage. ebay amazon special. the rearsets no clue but the look like the cheap stuff I've seen sold thru the same places for groms, etc. I had a set that aluminum.was super soft . whoever built that bike likes cheap as fuck parts.

That bike is beyond ugly!  Seller states "Starts easily, idles cleanly, and pulls strong." That's a pretty bold claim considering the bike has no chain. :rolleyes:

And the oil spigot port on left carb appears to open, while the one on the right has a piece of clear hose on it. Not sure what's going on there but I suspect he's got a nice air leak going on. Wonder if the pump is still under the cover?

Here's a better pic of the Thai SR parts.

The idea of a cable-pull hydraulic conversion... If all you needed to do was run the lines?

there's no big hyd advantage. the master is not much smaller than the slave.like said, I have one bought it 10? 12 yrs ago. garbage.

besides no chain- no air cleaners, no front brake caliper. Yeah I bet its tuned crisply and stops on a dime after pulling strong all day long  :whistle:

Looks like you nailed it Mark.

Too bad. Seems like a good idea with poor execution.

Damn that seat is ugly... For sure they like billet aluminum parts in SE Asia.

it mostly seems to be 5000 series at best, that aluminum is typically like butter. sometimes it doesn't matter.. sometimes it does
