KZ, I just get my NT400Bros recently and haven't been riding it that much, one thing I can tell you, it won't win you in acceleration any price, my SRX4 takes off much faster; but, front brake is incredibly strong, and it pulls constantly up to 130km/h, didn't test her topspeed yet but it should do some 150-160. Watercooling, vibrations and torque is also a plus compared to the single thumper, once you get stuck in traffic the SRX gets pretty hot. Only the right exhaust pipe is putting some heat on your foot as it passes right in front. Bike's strong enough also for a passenger joining you, petrol consumption very low but here the SRX is the master !!!! THB 50k and legally registered is a good price as now also the Thais considering much more the big bikes as high costs of living are eating into everybodies purse. One more thing about NT400 and also SR/SRX 400 is their unique & timeless beauty, that was reason enough for me to get both. Technically, you'll have to do a lot of repairs as once a young new local 'mechanic' has had his hands on any of these bikes you're in for some 'surprises'..............I'm doing all on my own, so if something fails, what I don't expect, I can only blame myself.......Get yourself one as you won't find it too hard to get spares for either of these bikes NT400&650, SR400&600, SRX4&6. Cheers, Franz
