Actually bought a used one but was in really very good condition. The riding was pretty smooth. I think the pickup was very powerful compared to its segment.The engine is reliable and smooth as always like the Yamaha bikes.It has got killer looks in its segment but actually I like the looks of BS4 FZ25, but due to short budget I went for the FZ but never regretted.Maintenance is not on the costlier side or on the cheap side. I always use motul synthetic oil and it gave me a very good feedback. As i bought a used one, I used to service it occasionally in a local workshop I knew and not in Yamaha service centre. I used to service my old scooter in the same workshop and he had done a pretty good job.Now moving onto the pros and cons,So talking about pros, I think everything will be pros1.Breaking is excellent for a 150cc bike.2.The engine is both reliable and got a sportier performance compared to other bikes in the segment.3.The seat is cushioned nicely and will give you comfort in long rides. Both pillion and rider will be satisfied.4.Handling is an important aspect and Yamaha had done a pretty good job there.And everything else was just as I need it to be.And now talking about cons1.Headlight is good but not good enough for long rides. For just city rides it is enough but you will need auxiliary lights for long trips.2.The tank is made of fiber so magnetic tank bag cant be used for touring. But u can tie up the saddle in the rear.From my point of view apart from above points I didn't feel any cons in the bike. It was a pretty good deal in its price segment, Yamaha had done a very good job there.
Tips for Yamaha FZ FI
