Long time KiwiBiker!

I've picked up an Aprilia RS250 1994 and having issues sourcing general parts (don't tell me it's a 20yo bike) :'(

Currently I'm chasing a front brake lever switch for the old girl, currently i have part number (AP8124597)


but I believe I need (AP8124288), I think it shares with multiple bikes RSV's etc

Anyone have these laying around?

What make are the brakes?

Looks a lot like what I just replaced on the brembos on my ducati.

Try ducatispares (https://www.ducatispares.co.nz/) likely a brembo part...

one looks the same as a 916 other than the block connector that can easily be swapped over.

Nice. Mk1 tailpeice look much better . I had a mk1 like that on my YZF750SP.

Just got off the phone with a mate helping with a mk1 rebuild not 10 min ago.

There's an RGV website that used to cover RS250 as well.

Just be sure you are not dealing with fuel blockage as people put sealant in tanks to stop rust but it covers breather holes.

Apparently, the UK RGV250 forum has closed down after 25 years :'(
I've applied for FB group access, for the fuel tank vent block that's a good idea
I thought the vent holes were the breather but it's actually the tank lid

Great to know that there's a few of these RS250's around!

Ahh, I used to frequent there, but not of late.
