Royal Enfield Thunderbird Twinspark features and specifications
Royal Enfield Thunderbird Twinspark has brought a sea of change to the Royal Enfield stable, which until a few years ago was dominated by models which had hardly seen any major change since India’s independence.
The Unit construction engine (UCE) marks a dramatic shift in the traditional Royal Enfield engine architecture. This is world away from the traditional Royal Enfield engine, which has an external clutch and gearbox. In Royal Enfield Thunderbird Twinspark, both these elements are integrated within a common crankcase space. This makes the Thunderbird Twinspark’s engine more compact and reduces transmission loss, friction, maintenance and while at the same time being more reliable than the traditional Royal Enfield Engine.
The new Thunderbird Twinspark also incorporates hydraulic tappets – which are a first in India and combined with the new lean-burn combustion technology and twin spark plugs, give better power, torque and fuel-efficiency. The clutch in Thunderbird Twinspark has also been beefed up with an all new 6-plate one.
This makes the new Thunderbird Twinspark not only the most powerful 350cc production motorcycle in India; it also makes it the easiest Royal Enfield to ride.

Thats a very cool bike. I am planning to buy one…
perfect bike .amazing features.good looking bike then the other model of royal enfield.
Thunderbird twinspark. It’s very good to look and ofcourse to ride smooth on the way, but……
Something missing like, digital meter, blade style alloy, a pair of tubeless, and if you can to change the rear drum brake to a disc.
and the real atraction catch by the long silencer.
‘Anyway….
IT’S VERY VERY
WONDERFUL…’
“THE TARZEN BIKE”
this is the worst enfield bike which i hav seen….. plz dont buy dis, its just a waste of ur hard earned cash…. insted of twinspark u can buy the old thunderbird…. its really a superb bike….
Hi Friends, I’m very happy & oriented after reading the comments … Actually i was never in the favour of RE bike because of their starting problems .. because during my Engg days, i used to be first chap to leave the hostel premises on my Bajaj bike & leaving RE chaps , facing the staring problems…
Please tell me about the maintenance aspect of RE , TS , beacuse till now no body has highlighted this aspect of this bike.. Will the periodical servicing is enough for the maintennace of this bike or u will have to really work hard/put money to keep it fit.. pls reply this thanx
But last week i had taken a test ride at IIT Campus for the first time in my life of a RE bike & that too Thunderbird TS, I’m amazed to ride the bike & felt the pick up of this giant Bike…
I’m satisfied and might go for the bike within a day or 2 but i’ve one question from the existing users..
Still missing:
1. Tubeless Tyres.
2. Rear Disc brakes.
3. Headlight bulb is tooooo small.. just 35W on highway. should increase it to 65W or 90/100 W.
HELLO .i recently purchased the thunderbird in january and now bike has run 2200 kms…oil leaks….fuel efficiencyy is also very low around 34……loosening of partsof bike,,,,vibration too much…exceedin than the bullet….i contacted the showroom mechanics for the problems…regarding noise of the engine..they just say it;s normal…but it;s isn;t.they don;t know anythin about this engine…..on company.s site they say that hydraulic tappets reduce noise..but it;s makin noise like that of a diesel engine…it doesn;t even hear like a petrol bike…if any one could have driven old taurus bullet diesel could see the resembelance except that was smoot…i feel my money;s got wasted…better had bought a standard or electra…bullet…or go for karizma or pulsar 220…. this advice is to everyone who wants to buy a thunderbird twinspark
people are sayin that most of the bikes have been sold through internet publicity..now i will post on the net the real problems I;m facing….
Thanx for your CHEAP .Slow and tiresome Service`..
very Bad experience …
i’ve bought a THUNDERBIRD TWIN SPARK a month before.
it makes me sick.
it has much more vibration and sound like a diesel auto.
people who wanna bye think twice before you buy.
all your money ll be wasted if you haste.
i could not even ride more than an hour.
i bought that stupid bike with dreams of getting riding pleasure on highways.
it should have been my pleasure that was increased but
it was my blood pressure that got increased.
if you wanna buy this baggage of junk. . . oh no. . . i need not mention more i think.
i bought this bike a month before with lot of expectations. but not even half of it is fulfilled. usually the thump comes frm the silencer but in this bike a noise like diesel auto comes straight frm the engine.. eratic sound not at all comfortable.. that noise comes down only at 70 km/hr.. apart frm that oil leaks easily and the RE people are unable to correct it. i think its not as worth as it was hiped… sooooooo sad
I’ve been driving Thunderbird since last 5 years & have planned to buy new TBTS UCE with thorough check. I completely disagree with the above comments where so many problems were highlighted like oil leakage, vibrations etc infact this new Unit construction engine is so reliable and effecient that RE will be introducing it in his all bikes by 2011. I’m die hard fan of RE, they dont produce racing bikes but they produce great bikes. By the way even Yamaha RX 100 too had oil leakage problem if reved over normal limts so does that means it was a crap? Use your brains guys !!! RE is not for everyone, one needs a big heart to sit on it.
this is the wonderful bike.I likes this bike a lot.
i was planning to buy a RE TB TS, but after reading all these comment i m confused……..so friends pl. help me on this……
Guys , i agree with you’ll the service cener sucks like its engine , the engine is very noisy , got this TBTS going through its specks , RE 500 is far too good when compared to my bike , I had to change the silencer to a free flow GoldStar , so i could listen to the Thump , but its got good power trust me on that , but then you dont feel like taking this bike on an open highway ,
any one planing to buy this bike pleas just drop the plan… Go for a Standard Classic or the 500
Guys, I own thunderbird twinspark, purhcased on May 2009. I love the bike but I have a problem with the front disk brake. It makes hell a lot of noise when you apply it. However, the brake shoes were replaced twice in the thunderbird service center itself with no avail. It still makes sound. Probably I should fine some good third party break shoes. I owned pulser before, never had this problem……not even once in pulser.
It is a wonderful bike.. It is a cruiser and have been cruising on it since I own it..
It was my dream and I am happy to own it.. Thanks to Royal Enfield.. only tubeless tyres are missing the rest is amazing for the amount.
I doubt any RE will appeal to people used to the Jap no-trouble bikes. Enfield’s are Enfield’s and will always have problems. If you do not have the time or the patience to maintain and take care of them, stay away! These are not bikes you can use like regular Hondas/Yamahas/etc.
In short, those of you thinking of buying a Royal Enfield (even if it is the Thunderbird Twinspark), remember that it’s not just a purchase you’re making. You’re entering a marriage. Treat her with respect and she will treat you equally well. Forgetting to service and maintaing her will give you a constant headache.
Overall, the new Twinspark is an excellent bike and I commend Royal Enfield for a job well done. But the old nags and glitches and pains still stay. So keep all this in mind before blindly buying it and expecting it to work like a normal old bike.
Hi guys, i hv buyed thunderbird twinspark in jan 09, and i m really disappointed with the engine sound, so i finally changed the silencor & fixed a jet silencor now, ohhh! Now with this new silencor the sound is like a rocket, i m really enjoying now, but i m scared that, will this new silencor decreased the mileage? Somebody help me..(9846228889)
it is a very good bike ,very good pick up ,cool looking……….i am buying one…..everyone listen if u take care of your bike you wont face any problems…
if u have a thunderbird twinspark then dont worry please ride ur bike slowly for atleast 5000 km then u can feel ur bike cooler then ever i too faced all problems but now its cool ……so just ride ur bike within a speed limit of 40 max 60…then after 5000kms u can just fly thats TBTS….got it
Hi guys……I am a proud owner of a TBTS. It is very good bike. I bought it in OCT’08. No problems as such except for a small oil leakage. That can be taken care. It has got a nice sound too.Sounds similar to a neigh of a horse wen u start the machine.I am loving it.Maintanance is not a prob. Timely check up is sufficient. Go for it guys. Its worth your money..
Dear Sir,
I procured one Thunderbird motor cycle from Bathinda dealership. On making various enquiries from dealerships at Chandigarh, Patiala, Rajpura, Ludhiana i/c Bathinda, I was told that Parado alloy wheels are suitable for the bike and these don’t violate the provisions of warranty.
Accordingly I made a search & procured it from M/s. accurate accessories, Ahmedabad and got it fitted from Royal-En-field workshop at Bathinda. After fitment, it was noticed that the directions of blades in front and rear wheels were reverse .On enquiry from the supplier, I was told that no company is manufacturing alloy wheels for RIGHT SIDE CHAINED Thunder bird bike.
Through this long story, I want to request you to please let me know the source from which I can procure such wheels for the prestigious bike. You may please forward relevant website or e-mail address for my further pursuance.
Expecting an early reply and with thanks & regards.

Dear friends,
1st of all if u like and are satisfied with bikes like karizma or pulsar then trust me u dont know what RE is capable of. The people who compare RE with other plastic bikes manufactured in India are not worthy of owning one. There is no point in complaining about the weight of RE bikes because it is designed to give u a stabilized and center balanced ride which only comes through the higher weight of the bike, unless u want to duck under a hood for stream lining. I bought my TBTS some 3 months ago and so far ive had no problems with the bike. It feels like a glider when cruising through highways. The initial pickup is higher compared to its 350cc counterparts. The mileage is much much higher. Im getting close to 50kmpl. The noise of the engine is a bit of a worry but it disappears when u shift to the 5th gear. And with the helmet on u hardly hear the noise. Only the thump is audible with a helmet on. The same is the case for ur pillion without a helmet. The classic 500 and 350 are out in the market and they use the same Twin Spark engine. If it was as faulty as the opinions of people above, then RE wouldn’t have taken the risk with the engine of their long awaited model-revolutionizing bikes ie the classic 350 and 500. And after 1000kms it some what sounds like a Harley. If u have vibrations in your bike then sue ur service center and find a better one which can fix it. Im experiencing no vibrations even at speeds exceeding 80kmph and neither are my friends who have been riding it for over 10000kms.
Dear Pritpaul Sohi ,
If u dont mind keeping the the spoked wheel then i would suggest it over alloys anyday. Because they r much more comfortable to ride. And the look is great aswell. That was just my opinion.
good article,my brother own , just amazing bike
Folks,
This is nice bike it seams…I have tried it & I feel very comfotable…. Take care of your budy..

Hi Friends,
My name is Manik and i am a working professional.
I read a number of mixed reviews regarding this bike and was confused at one point of time. Not only reviews, but most of the people i took suggestion from also had some mixed kind of views regarding the bike.
I was thinking to buy this bike for the last couple of years, even before the TBTS was launched. but every time i plan to buy the bike someone changed my mind and my program was delayed.
I even testdrove the bike and even i feel that there a re a number of limitations in the bike, like the kind of vibration it has is annoying.
Also i noticed one thing which i did not see in any of teh reviews. The black colour of the bike fades very soon (may be in a year or 2).
If you want to buy a RE, never ask for suggestion. You will always get the answer as overprice, maintainance, oil leakage, gear shift problem etc etc…
So now i believe that if you want to own a RE, you have to have a passion for that. i agree it is a big investment for a bike, but trust me it is a asset for life.
Finally i am going to book the bike today. I hope it will fulfill my expectations.
cheers
JUst booked the monster of the roadies……
I have being in love since my childhood days, but never allowed by parents as bullets are heavy in nature..But now i have booked…Had a test ride…and its just wow….Hope my bike ride will be always wow…..
Only problem its in so much demand , u actually have to wait for 45 Days…SAD>>>>
guys- i have a TBTS and have been on it for close to 2 years now with over 25000 kms clocked… have been on a lot of bikes all thru my lyf… none can come anywer close to this monster…
the bike lives up to its billing… its just that- IF U TAKE CARE OF HER, SHE WILL GO ANY LENGTHS TO TAKE CARE OF U…plz do a proper running in for the first 5k kms.. never got stuck cos of the bike… giving a mileage of well over 55km per litre now… the max achieved ever was 68 k’s.. .swear to god on dat..
its the only bike dat can make u feel rock steady at speeds close to the 3 digits- can go upto 130kph if u strain it a bit n put on a K&N free flow intake..nd mind it- its not for the weak hearted!
