If got b full might and you plan to upgrade, better off just skip 250 and straight to 650.. Yes it's more powerful than 250, but the power band is rather forgiving.. Only worries is the weight.. I have never rode big bikes before and also more than 10years never ride bike.. Straight got myself an er6 as my first big bike..

Weight means it's heavy lor, haha.. Btw, different ppl different thinking la.. If you really not confident in handling the weight then just proceed with what you're comfortable with.. Anyway, can consider used ones since you just want it as stepping stone.. I bought mine used too, after 3years ownership clocking 60k km, I still manage to sell it back slightly higher than my buying price.. But I never stingy on the maintenance and accessories la, hence can sell at better price..

For test ride if your in Klang Valley.. Selangor TM motoworld or Puncak Alam Motoworld.. KL Motosikal Mok.. These 3 shops I know can test ride used bike and also very friendly boss.. I've dealt with them.. Most important they never mess around with "fake" mileage, coz some shops you look around you will noticed all bikes low mileage even though very old.. definitely very fishy.. These three shops sometimes will got bikes 100k+ km and they sell as it is..

TM and Puncak are brother's company.. You can look for Jordan in Puncak.. They never stingy on letting customer test.. My 1st er6 was recommended by him.. I was actually eyeing z250 that time, and after some chat, he says er6 suits my needs more.. So he push out the z250 and er6n and let me test both.. When I confirm er6n, he even push another er6f for me to test which ones I like.. 2 of my friends who accompany me go on 2 occasion like bikes but have clearly said not intending to buy yet, still he push out bikes for them to test.. Thumbs up and highly recommended for these kinda service these days..

Typical Malaysian style.. When not brought in, bark like no tomorrow.. But when brought in, better this, better that..
