Royal Enfield 650 Interceptor fitted with the 865cc big bore kit with dyno testing

[@daveg4495]

I purchased a set of header pipes from H/C & not only were they cost effective, they arrived in less than a week in Canada!!!! The pipes took me around 1/2 hour to replace on my Interceptor 650. Excellent service & fit. Someone at Hitchcock's knows what they are doing.

[@SrinivasGanesh]

I completely agree! I love their products!

[@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.

[@xenoark2849]

Well put, im on the same street, why change bike you already like if you want more power and you have an option to do it. Plus doing all the upgrades makes it even more personal and more special

Come on then, kit looks amazing but if you took all recommended extras to upgrade to 865 cc, how much overall £2',500, before VAT and fitting costs? Think this kit will allow the Interceptor to realistically compete against it’s competitors but as always will also come back to overall cost of upgrade. Great step forward though.

[@TheRIZKYRAMA]

What competitors? The only bikes that competes with this is other classic bike like kawasaki w800 which has the same power. If you are talking about modern engine bike with retro look like yamaha xsr700, it can't be compared. it would be a different animal because those thing uses modern tech like liquid cooling, short stroke & lighter engine to generate more power. Obviously, RE could use also uses modern tech if they wanted to, but they are not trying to capture that market segment.

[@canopus101]

This big bore modification will be popular and I would dearly like to ride an Interceptor that was modified in this way. That said I will not alter my Interceptor to this degree. I have fitted DNA filter and Lextec silencers and am more than happy. The whole point of buyng the machine, to me, was to ride in a different manner. On my bike I am not looking for the overtake at all times, I flow with the traffic. If things stop I filter, if things slow i drop a couple of cogs and blat past. On other times, most of the time, I trundle at 50 to 60 mph and enjoy the ride. The joy of the Interceptor is reasonable performance, great looks,good handling, amazing fuel economy all at bargain basement price. Rather than spend thousands to achieve a better performance I would buy a bike that could do this in standard trim. looks fun though, I must admit, and if I was offered a test ride I would enjoy it!

[@leandroflaherty]

What bike looks as good as the GT, with the big bore specs as at under 10k?

[@randombully3798]

Seeing the rear wheel numbers, assuming similar percentage difference in performance at engine and rear wheel in the 650 and 865 will give u 75-77 hp and 86-87 nm of torque at the engine for the 865cc gt. That's pretty good and more than triumph speed 900.

[@eazyrider6122]

If it aint broke don't fix it, These bikes come with 3 years warranty also. Ill big bore mine when the motor needs a rebuild. Until then i have my Triumph 07 Bonny 865. Also a Shovelhead fore even more punch. I personally love the 650 Enfield as it is for now just a stage 1, Mufflers, Fuel booster and a DNA free flow filter was all good. This can all be easily reversed for warranty within an hour.

[@DD-co1zn]

'I love mine as it is, if it ain't broke don't fix it' ... Also I own a few other bikes. Also it isn't broken, and I love it as it is, but I have actually fixed its mufflers, cam shaft, air filter, EFI fuelling. 🙄

In terms of engine modifications, I have a couple of queries. Firstly, the stock Royal Enfield 650 twin has a compression ratio of 9.5:1. Do you not think this could stand to be increased to 10.5 or even 11:1? Could this be achieved by simply shaving the head or would it require piston relieving or even replacement? Secondly, given that here in the British Isles we "enjoy" a climate that rarely exceeds 30 degrees C. and indeed rarely sees daytime maximums exceed 25 degrees C. for a week or more at a time, is the oil radiator really necessary on the RE 650?

[@HitchcocksMotorcycles]

Hello, it will really depend on how you plan to use the bike and setting this up to suit your individual requirements. The actual frame itself is more than capable to handling the extra performance, and this should not give any concern. For the suspension, we have upgraded this on our bike and did so when the bike was in a 650 form, but this really comes down to a personal preference and setting this up to your weight and riding style is beneficial. We have fitted uprated brake pads and discs to our bike, this offers a good performing setup.

I imagine most buyers of these are "middle aged" and have a garage with plenty of space. Also that few do more than 5,000 miles a year on them and rarely venture further than 50 miles from home. This being so, I heartily recommend a good Japanese or Italian middleweight twin from the 80s or 90s. A smaller Guzzi or a GPz500 or one of its more recent descendents. These bikes were well made, light, usable and had real soil, rather than a facsimile of what the design team imagined soul might look and sound like. There a loads to choose from.... and they are all swift, viscerally energising and a joy to ride. Plenty of good ones left, if you look. These things are somehow Tonka toys in comparison.

The 865 kit is fine but I wish they made a 750 kit which would match the original 750 Interceptor because in my opinion RE biggest mistake was not to do exactly that. The whole point of the original Interceptor was that it was the first 750 British twin made in 1962, so why build a 650 version now carrying that famous Interceptor model name?
