Never had a bike without a centre stand before, so: Should I look to buy one that fits the bike, or do they all work? (Sprint RS, hence double-sided swingarm) Do they vary in quality? What's the difference? How do I use it, since there's only me here to get it on it (this is a detail question, I know *in principle* how they work) Can you use them on slightly not very level ie sloping ground, since I don't have a lot of very level ground round here? Any recs re models/makes? TIA...
