All rs 250s (aprilia) vj22 suzuki RGV motor.
As said before by others ref service windows but and this is the big but. Its been owned by someone else so. I always do a strip down and at the very least chuck the rings and install new ones. Then again i never do the least and replace rings little end and piston pin as standard. If there is even a hint of wear on the piston, that goes as well. I use pro-x pistons and suzuki piston pins as the suzuki ones are lighter. Next use fully synth oil brand unimportant but i like repsol because the bottle is green.
check the barrel for wear ie bad scoring. Light scuffs can be rubbed with a bit of fine emery if it makes you feel better. Pay special attention to the exhaust port bridge look for flakeing or cracking. If any of this chuck or get re-coat. My last new cylinder was about $750 nz. Watch out for worn power valves as this motor has issues with these and suzuki modified these as they failed frequently with bad piston and bore damage. These are expensive.
Thats the potential baaad stuff, as for the bike very very good. Handling is fast brakes up with the best modern stuff. Nice over front riding position. Power can be good if set up right and on this bike a pair of aftermarket zorsts work well, i use the tyga ones.
This bike could be a handfull for a new rider as power delivery is not proggressive and is a little peaky but this also makes them fun.
Most of my youth was spent on RGVs, and most of my near death experiances were on these bikes so, if new beware they are single minded and they do bite back if treated without some respect!.
I have at this time an NSR MC21 and an RS 250 1999 model they are both very good mounts but i wish that Aprilia had put the NSR motor in their frame as it is the better motor all round. For racing the vj22 motor can be made to put out impressive ponies but at a cost.
If it were a choice of an NSR or RS for the road i would go for the NSR its just a better bike all round but i love them both so i now have one of each. Both race bikes as i think they are wasted on the road.
Hope this helps ask more if you need more info.
