Hello

I'm new here so please try to be gentle!
I'm currently trying to work out a solid plan for marrying an RG 500 engine with a more nimble chassis for a classic GP replica with a modern twist.

I know the Aprilia RS250 chassis is the common choice for these hybrids, but I'm strongly biased towards an MC28 Chassis with ProArm swingarm, simply because of my love for RC30/45s. Bit of nostatlgia going on there.

But from a practical point of view: You guys would know best. I know NSRs can be a nightmare to derestrict and such, but in this case a rolling chassis is the only thing that matters.

Engine performance aside: How does the handling of an MC28 compare to the RS250? As far as I know both bikes were designed using GP technology so neither should be bad, but I want to achieve the best possible handling and lowest possible overall weight.

That also leads me to ask: would any of you have a rough idea of the weight of an MC28 frame and swingarm? And of an RS, for that matter?

Thanks kindly for any advice!
