Pros & Cons

Pros
Cons

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.
Triumph Speed T4
- Good looking motorcycle with excellent fit and finish levels
- Good sounding exhaust note
- Fun to ride in the city with easy and smooth power delivery
- Fewer gear shifts required in the city for overtakes and commuting
- Comfortable ride quality with good bump absorption

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.
Triumph Speed T4
- Looks too similar to the Triumph Speed 400
- Misses out on premium features and components like inverted front fork
- Highway performance is compromised for better city rideability
- Weighs 4kg more than the Speed 400

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

Nice performance bike
Nice bike with very good performance, sitting posture upright and commanding, mileage is good as its a big cc bike I can get around 30kmpl in highway and 24-26 kmpl in the city. Royal Enfield service is also very good and its low maintenance as compare to big bikes like triumph 400, so overall its a amazing bike and its thrilling to ride the bike.

Good bike from triumph for indian’s use
It is my dream bike which i wanted from triumph since i was child and which is now full filled. It is very easy to use for me in city traffic. And it is a good bike as a beginer as well. I have got good complements as well for this bike. The riding in the city is very comfortable and easy compared to some Royal enfields, and it have got a really nice torque which gives me a really hefty boost of energy while riding on the empty roads. You should buy this bike if you are mostly going to use it in the city. Because of its really good mileage and of you are a college boy/girl, it is filled with good amount of acceleration for some fun time as well.

Excellent Bike for City Users and Highway ride
I choose this bike to because I loved the design, power, pickup and the presence of the bike as per sales person suggested me to choose T400 for City use as such it's more comfortable upright posture and best bike. Bike gives excellent response on corners, traffic, on long rides I had few rides from Pune to Gujarat it felt comfortable on long rides and it's seat height is more it gives more ground clearance on offroad . I would recommend it to All People Working, want to have a daily commute bike it has feel of luxury, a British motorcycle that's fun to ride, feel, road presences with good looks that's too in great price under two lacs rupees

Low mileage, high maintenance, uncomfortable rear
I bought this bike purely based on the spec sheet and it's aggressive pricing challenging meteor and classic 350 which it out weighs in specs by a mile. The position is also very non aggressive and the only triumph which didn't give me wrist pain and that lovely lovely smooth gear box . The mileage performance has been horrible even though I try my best to keep it between 4-6k rpm going out of my way to face discomfort and vibrations but barely got 22 in city also the rear suspension seems to not work at all. I wouldn't recommend anyone buying there first bike to get this I am already regretting is the power is too much for a beginner and the maintainance is too high. I think the xsr or the highness will be better vfm and more reasonable as a first bike with low maintainance cost and smooth engines.

Highly recommended bike Triumph Speed T4
I choose this bike because of it's attractive look and affordable price and comfortable ride. This bike provides a better and comfortable riding experience which is it's best attribute . It's mileage is also better than other roasters which makes it better. The riding experience is one of the best I had on any of the bikes I ever had. This bike's efficiency and design is appreciable. The thing that makes riding on this bike better is it's design and featured seats. I would recommend this bike for sure. If you are looking for a bike which gives you best riding experience with good looks and comfortable riding in affordable price then I would strongly recommend this bike

A 1000 KM review
I was searching for a better ride option I had multiple options like hunter 350, jawa 42, yezdi, cb350, x440 but after comparing with them I found t4 to be a better product than all for me, As it offers better torque power and ease to ride option. I have done multiple long trips as well as rode it on city roads as well I found it in city it overheats a lot while in traffic or riding it in smaller gear on the other hand I cruised the bike for a long time on highways and there is no issue in it. Front Suspension can be better for multiple riders as it offers telescopic but it is also a personal choice for me it does not affect a lot. Yes, I can recommend the bike but before buying make sure what you want if you want to just roam around, go for a commuter I must say but you have mixed usage which most of riders have, thn go for this machine.
