Royal Enfield 650 Twin S&S 865 Big Bore Kit Fitted, Tested & Review by Cooper Motorcycles Ltd

[@madhusudanchakraborty7556]

Come to India a lot riders are waiting for these type of mods

[@jogarao4471]

lot of riders? you are living in a dreamland. Sales figure for April : Classic: 23,298, Bullet 9,900. Interceptor: Only 1290. Very few indians want a fast bike with 860 bigbore upgrade costing the cost of another interceptor. For the same money you can buy a big 4 cyl Kawasaki or Suzuki superbike.

[@MrJulianneave]

All these people saying "why not just get a 900cc Triumph"... Well, I've done a fair few modifications to my interceptor and am now considering going 865cc. My thoughts on it are: - Some people don't want yet another Bonneville. Nice bikes, but common enough that they don't have the unique factor of the RE. At least here in Australia, Bonnevilles seem to generally be an "old man" bike whereas RE seem to have a bit of a younger appeal which is fun. -If you go and get the 900cc Triumph there are still going to be things you want to change. Sure they come with more power right out the box, but in reality you're still going to find yourself wanting to swap mufflers, headers, intake, etc the same as you do with an RE, because all those items still give appreciable improvements in a Bonneville. Except they're a lot more expensive than they are for an RE. - Not everyone buys an Interceptor thinking they want more power right away. It's my first big bike and on the test ride I was really impressed by the power, since in reality they're not a "slow" bike in the way that people jumping off a 1000cc machine like to say they are. But after a year and a half, I'm starting to think more power would be nice. Options are: A) Develop and build a time machine to go back and purchase a faster bike instead of the interceptor. B) sell the interceptor I've taken to great care of and suffer the depreciation losses, and try to find and buy a second hand a higher power triumph, accepting the risk I get a lemon that the owner has not taken care of. C) Keep the bike I like, that I know has been taken care of, and which I've got some great memories with and spend the money to upgrade it. This leaves you happy with the power and you've got all the other modifications you liked enough to do, that you'd only have to go and do to whatever triumph you bought in Option B at greater expense. Yes it's expensive, but all the options are. For my money and in my situation option C makes most sense. If you don't have a big preference for the RE over a triumph for any reason and know you'll want more power right away, get the triumph instead of ever buying the RE.

[@aryanbairagi4925]

its a step by step investment, costs half of a triumph and you can go step by step increase power with added accessories and big bore kit.

[@jasonrichardwatts]

Summed it up perfectly. 👌

[@ben9l351]

ignore big bore kit ............get a 2 into one exhaust and an SS camshaft kit maybe a new ecu and air filter to accommodate and you have 15 extra HP the trade of is slightly higher revving

[@jasonrichardwatts]

@@ben9l351 I'm installing the S&S cam, TEC stainless slip on mufflers and a high flow air filter. Of course it will be dyno tuned as well. A LOT cheaper than the big bore kit and less than half the cost. The extra half and a bit cost for the big bore kit will see another 5% in HP/torque but I can't justify the cost as the cam option pulls like a train and sounds CRANKY!

I’m holding out for the Super Meteor 650 model first before I do all this. I like the Interceptor, but I think I will love the SM650 even more. I can’t wait to ride that in for a year or two and then get a big bore kit fitted with all the trimmings. It’ll be a proper little cruiser with a good amount of grunt and I simply cannot wait to ride it, as well as mod it.

My 61 Norton Dominator SS 600cc factory stock no air filters. And since the Coñor Candy Apple Metalflake Orange lacked depth I went with a unique looking Candy Apple Metalflake Apricot. And even the Dunstall Norton in Red did not look like as much of a cafe racer. But if I do get an Interceptor I think I want it painted British Racing Green just because it’s somewhat unique on a motorcycle and with the right pinstripes would look awesome

[@lakshman0680]

Hi. Great job. Lovely upgrade to the 650. Is this possible using the stock throttle bodies, injectors, the stock cam and the stock cylinder head without any mods at all? I'm guessing a new ecu map will be required but do any of the other parts require changing as well?

[@MegaCooperb]

Hi, this one has standard throttle bodies & head. If we were going for more BHP we can port the head & there are some kit throttle bodies etc. We used a Power Commander to get the fuelling right.

Hello I'm planning to install s&s cam on interceptor 650, I already have installed slip-on, DNA air filter, and powertronic piggyback ECU. If I install S&S camshaft with these already installed, do I need to install any custom map on the powertronic ECU or stock powertronic ECU maps will do the job?

Many would like the 865 on a bike with the suspension travel of the Himalaya and a 300mile range. USA wants that kind of bike. I think RE will succeed. Many people want a simple quality affordable bike they can easily maintain. Many do not want all of the complex technologies and expenses. That is the reason for the Bmw R9T success.

It's amazing what it can be done to this bike, but the investment throwing in to gain more power as for overall price it could go up to the same price as the Triumph Speed Twin wich is already a 1200cc with 100bhp, not sure if the investment upgrade is worth it.

[@troykelso]

[@GrimYak]

@@troykelso so what's the point? At the money you spend modifying this you are better off buying something better for that price. The lure of the Interceptor is price to performance. Doing this will remove the price advantage

Why did a 650 Bonnie blow my mind... 1972....or a 750 Commando in 1973 also blew my mind....and head gaskets....Where did the Raw mid range grunt go?

[@highplainshollarhomestead3188]

Is the Himilayan engine the same as the 650, just smaller bore/stroke???

[@MrMRSAF]

No its a different engine altogether. Its a single cylinder.

[@highspeedboom]

I currently own a RE int 650, and have owned other faster bikes. I am sure it would be fun but I don’t think the extra cost would be justified. Maybe if one did all the work themselves. So the way it brakes down 6,500ish for the 650, plus 4 to 5 k more , for 11,000 usd you can by a much more powerful bike. Maybe not with as much character as the RE though. Too much money for modest improvement

[@MegaCooperb]

This is all about choice. As riders we all like our bikes to be slightly different, that's why we personalise them. The price is less than a full carbon race fairing hung on titanium mounts for a modern track bike & lots of riders choose mod's like this. It's not cheap & not for everyone, but having ridden this one I think it's a great addition to an already great bike!👍👍

[@andersbarfodsvaneskolan9378]

the stock engines 47hp is relaxed considering that the engine is not a long stroke engine (bore = 78mm and stroke 67.8mm),, the bike has a low compression for a modern twin cylinder bike (9.5:1),, It should not be hard to push up engine HP and torque by 10% to around 52hp by increasing the compression slightly and altering the ECU and airflow (and use good european fuel),, a decrease weight with lighter pipes. I think that indian bikes are made to run on low grade fuel (octane 91).
