                • Royal Enfield Guerrilla 450

                  • The bike gets the same engine as the Himalayan 450. It offers plenty of performance in the adventure bike, so expect similar levels of performance in the Guerrilla too.
                  • Being lighter and smaller than the Himalayan in terms of dimensions, the Guerrilla should be easy to manage in everyday commutes.

                  • Smaller engine should offer slightly better mileage
                • Royal Enfield Guerrilla 450

                  • Instead of the more advanced inverted fork, the Guerrilla 450 gets a traditional telescopic fork.
                  • The 11-litre fuel tank is 6 litres smaller than the one in the Himalayan 450. This may affect the total range in long rides.
                  • The 780mm seat height should be low enough for most of the shorter riders to place their feet on the ground comfortably.

                  Experience and Review of Guerrilla 450
                  An excellent bike with solid engine. It has that attractiveness to fall in love. Compact size, big blast. I choose to experience this machine for its style, liquid cooled engine, TFT display, suspension and everything. Long rides does not feel boring on this machine. It definitely give good comfort, mileage depends on situation, 17-22 in traffic and 23-27 on highway. The torque it generates is just fabulous. It has given me upper hand in drag races. Would definitely recommend this bike to teenagers and those riders who wants to experience the feeling of driving Himalayan. This machine is a segment killer, no other bike can pair with it except its big sister Himalayan 450.

                  Its amazing. Dont think too much, just get one
                  It is a beautiful bike- that never feels boring. The acceleration is undefeatable! and while it is sporty, it is surprisingly practical too. It's neither too heavy nor too tall, unlike the Himalayan. Its an absolute attention grabber and I love the colour I chose (brava blue). To sum it up- I chose this bike because it was beautiful, it was fast and it seemed practical enough for my use. I use this bike as my daily, and it has never failed me. It feels stable, planted, easy to manage. It always feels like i'm in control, I have not had a feeling of anxiety that it'll wobble, slip or be uncontrollable even once that I have ridden this bike even on high speeds. The fat rear tyre makes me confident even in rain. the feels grippy even on wet roads, loose gravel- though the bike did splash water on my back in rain, I just got the rear mudguard extender from Enfield and now it's not a problem, though I believe it should've been company fitted. The suspensions are comfortable for daily use, and even in Ghaziabad's bumpy roads I almost do not feel a thing. The engine yearns to red line, the bike wants to go fast and I love it every time I pull the throttle. The mileage is reasonable, with 25 on normal city commute (in power mode, using eco mode pushes that up to around 28. I can manage to get 32 if I ride carefully, maintaining gears to keep the engine at 4-5k rpm and not pulling the throttle/ yanking the breaks unnecessarily) It does get hot in the summers, but honestly I can smell the engine getting hot more than I feel it. Its hard to explain really, but hot air does not blow on my leg when riding so that's good, occasionally the win direction may align and the hot air may blow onto your face- but again thats rare. I am a bit conflicted on highway rides, because it is fun to ride on the highway, but the seat does make your buns feel sore after a while, but its manageable. highway mileage is around 28-29 in power mode, and around 30-32 in eco mode. I would recommend this bike everybody over any other bikes in this segment (except the adv tourers, if you can manage them ofcourse).

                  One of the best bikes in segment!!!!
                  I chose this because it's different from classic royal enfield bikes, it has better performance for city riding lighter weight, excellent acceleration a balanced bike with 450cc engine, ideal for smooth city riding and some adventure too just love it. My experience with this bike is lovely, it's my 2nd bike earlier I owned 125cc upgrading to 450cc just feels magical it offers smooth riding with enough torque and power to gap almost every vehicle on road. I like it's fast acceleration it offers a whole different experience for royal enfield bikes. Yes absolutely, I would recommend you to buy this if you are looking for 450cc segment than this is the best bikes, ngl ideally for daily riding or even if you want to ride on hilly areas it offers a smooth experience 40N/m torque will let you experience dominance on road.

                  This is a great bike which never disappoint rider
                  I was looking perfect combo of performance and the retro look of royal enfield. That's when I came accross this bike guerilla 450 a perfect combination of style, performance, looks, features. If someone is looking for an upgrade they must consider it. Pros that the power of 40 bhp can be actually feel while riding the initial pull on second gear and the bike goes insanely fast.this bike also got full tft display which several useful features such as navigation, etc cons of this bikes are its has low mileage as it's 450 but it also got lower fuel tank capacity which leads to frequent fuel stops. the initial low end torque of all the gears except 1st gear is way less. If someone is trying to upgrade their bike from 200 or 350 cc they must give it a try.This bike never disappoints in terms of performance, style and road presence. except for its lower mileage and less fuel capacity this bike is really worth the price

                  New 349cc Speed T4
                  I brought this bike due to specification only, and to avoid a classic because already own a meteor 350. I needed a bike looks like Splendor but perform like a KTM, basically wanted a good street daily commuter. I did have other options like CB350RS, RE Guerrilla, TVS Ronin etc. I did liked the simple look, good specifications on paper and cheapest price in the segment. It's a mix feeling of goodness and regression. The mileage of this bike is 19 to 22kmpl, I never got more than that. Seat and riding posture are very painful due to low height configuration on front side. It should have given a 18 inch tyre instead of 17. The handle bar height should be equal to body. Seat is cheap and uncomfortable but I fixed by my own. Considering a handle bar raiser now but not sure yet. Performance is not equal to the specifications on paper. Feels like an overhyped bike just looks good. It's a big no for daily commute. If you have a collection of bikes and you wanted another one, yes you can go for it. It's really looks good kept in garage. One you ride, you will feel something is missing. Adding to the mileage figure, disappointment will raise more as I spent more price per KM and getting worst experience.

                  Great Bike
                  I chose the triumph speed t4 for its power and road presence. It is a decent bike and I am glad that I chose this to be my first bike. Go for this bike without hesitation. Great comfort and handling overall. Also the exhaust symphony is great. The bike is comfortable for long rides although I did 2-3 rides with this bike. I can say, this bike has the perfect power and handling for a rider like me. The pillion comfort is a little bit on the bad side but is manageable. I recommend this bike because it has both looks and power along with its great performance and handling in both cities and highways. Gives a decent mileage on highway but a bit less in heavy traffic. Slick Bike.

                  A all rounder with a kick.
                  Most affordable, premium looking roadster with good low torque and overall great performance. I was confused between the CB350RS and this bike, but once I had a test drive, I'm really connected with this vehicle. Comfortable vehicle with back rest for the pillion. Riding triangle is not too aggressive neither too relaxed. Mileage is on the lower side but you kinda get used to it after a while because what it offers you by compromising on the mileage is amazing riding experience. If you are enthusiastic rider, this bike is for you. If you like a laid back riding, more cruising style, done go for it. On highway, it will easily give you 32 kmpl which is good. But in the city, it is just 23-25 kmpl in bumper to bumper traffic, in this case Hyderabad. If you are mileage conscious, this is not for you. But if you can compromise there, then you are gonna love this machine.
