1999 Aprilia RS250 Challenge – the 2-stroke racer


A beautiful 2-stroke machine by Aprilia with the given name of RS250 Challenge. Reminds me the time of MotoGP era where we still can see 2-stroke bikes on the race with 125cc and 250cc class. It was a great time and the sound the 2-stroke machine is nice. This particular Aprilia RS250 share the same engine with the lovable Suzuki RGV250 VJ22 but tuned for higher power output and styling that is so Italian. This could be a bike that you can even park it in your living room and stare at it all day when you are not riding it.

SBC stands for Suzuki Boron Composite that plates the aluminium cylinder inner walls with a special alloy plating that consists of nickel and phosphor alloy carrying boron bromide. This reduces the friction and increases the durability of the piston rings.  Continue reading “1988 Suzuki RGV250 – the closest thing you could get to a GP bike on the road in 80’s”
