I’m a 25-year-old rider from Bangalore (6 ft, 95 kg) currently using a 2018 TVS Apache RTR 160 4V (non-ABS). After a few close calls, I want to upgrade to a comfortable supersport or naked bike. My budget is flexible up to ₹10 lakh. I’m open to superbikes if they look great, but spares availability, service practicality, ground clearance, and E20 compatibility are important for Indian roads. I have tested multiple bikes: TVS RR 310: Loved the package. Best posture, great suspension for potholes, features, and comfort. My only worry is the engine refinement stories I’ve heard. I'm also worried that TVS might phase it out, and I'd be left searching for parts. Aprilia RS 457: Found the posture torturous and honestly didn’t get the hype around it. Hurt my fingers when doing a full turn with the handle. KTM Adventure 390: Felt unsafe due to excessive vibrations. I also don't like how adventure bikes look. Too bulky for my tastes. I'm 25 - should be able to enjoy my life! Kawasaki Ninja 300: Felt very outdated, and the engine character didn't impress me. The Kawasaki dealership experience was also quite poor. Aprilia Tuono 457: Posture was okay, but the engine didn't feel special enough to justify the high purchase price and service costs. Looks didn't impress me one bit. Suzuki GSX-8R: Comfortable and fast, but 11 lakhs feels unjustified given the high maintenance concerns. I loved Rishaad's review on it (great reviewer and presenter - send him my love!), but I didn't really understand what's so special about it. I could barely use 20% of its power :) I mostly ride in the city with occasional highway trips. Since I know decent TVS service folks, after-sales for the RR 310 isn't an issue. My main questions are: How bad is the refinement on the RR 310 really? Have the recent updates fixed the vibration issues? Is the 310 platform being phased out anytime soon, or is it safe to buy now? Should I wait for the 450 RR? Given my requirement for a comfortable posture and E20 compatibility, is it worth waiting for an updated Yamaha R3 or another 2026 twin, or should I just go ahead with the RR 310? I'm looking to purchase something in the March-April timeframe, but happy to wait longer if there's anything better coming up :)
