The TVS Apache RTR 310 will be a good step up from your current Apache RTR 180. The RTR 310 is a sporty machine with good performance and handling, which doesn't feel overly stiff or uncompromising and makes for a good all-rounder.
As you have pointed out, there have been sporadic issues with TVS' aftersales. But if you are prepared to deal with them - and it does seem like your heart is set on the Apache - then you can go ahead with the RTR 310.
If you are open to looking at other brands, the Bajaj Pulsar NS400Z, Triumph Speed 400 and KTM 250 Duke all make for genuinely capable alternatives, with the Bajaj and Triumph also offering you quite a bit more performance.
We would urge you to take a test ride and speak to your nearest dealer for aftersales of each bike so you can make a more informed decision.
