I'm interested in these bikes and also the Road Rockets. I have never ridden one and I am wondering what the riding experience is like?
I have a 1975 Commando 850 MK3 which I like a lot, really enjoy the torque and smoothness of that bike. I also have a Vincent Rapide which I have toured 55,000 miles on, again torque and smoothness on that bike are nice.
I rode a 650 single Carb Triumph last year , supposedly in good shape and tune. I really thought it had no go and couldn't see ever using a bike like that loaded two up on big mountain passes like I do with the Norton and Vincent.

I also have a 68 650SS, it is a punchy little bike, but too vibratory to go any distance.
One day I would like to split the cases and have the crank dynamically balanced. It's such a nice handling bike , but the vibes just take the fun out of it.

How do the Rockets do with this type of riding and are they reasonably smooth if given a dynamic crank balance? Torque enough to pull big hills two up with luggage?

Thanks
Glen

Hi Glen,

I think you'll find a Super Rocket or Road Rocket very comparable to the 650SS. Now, I have no idea whether the vibes on your 650SS are normal or not, but a hard mounted parallel twin is inherently going to vibrate a LOT more than a Commando or a Vincent. The torque is also not going to compare to the Commando or Vincent. To get much go you will have to give it some more revs and deal with the extra vibes, much like I'm sure you have to with your 650SS. As for having enough go, it depends on how fast you want to go. Again, expect a similar urge to your 650SS. If you want to have a more flexible, easy-going A10 at the expense of some top-end power, consider a Golden Flash. They're also much more affordable, though judging by your current repertoire, I would guess that's not much of a concern.

HTH,

-alex

Dynamic balancing isn't a magic cure for vibration. If you look at a current thread running in the Gold Star forum you'll see Phil Pearson quotes three different values for balance factors that differ by over 10%:

http://www.britbike.com/forums/ubbthreads.php?ubb=showflat&Number=598148#Post598148

Those widely differing figures, as is the case with all balance factors, are compromises that result in the lowest perceived vibration in a given frame at the rpm range of greatest interest (note: lowest, not zero). Someone can hit any of those balance factors listed in that thread using a static stand within the accuracy with which they have been determined.

Dynamic balancing is useful if, say, an engine has two flywheels that are widely spaced and if for some reason they differ in mass distribution. For example, if someone had statically balanced that crank by drilling a big hole in only one of the flywheels. In a situation like that the crank would vibrate up and down along the axis of the crank (as opposed to simply up and down maintaining the axis if the mass distribution had been equal). Such an imbalance would not reveal itself on a static balancer but would in a dynamic balancer.

Before going to the effort of splitting the cases, take the time to make sure all the motor mounts are tight as well as everything else attached to the bike. Since it's theoretically impossible to perfectly balance a vertical twin there always will be some vibration. If it happens to be at a frequency that excites vibration in something else on the bike (loose mudguard, oil tank, stoplight assembly, etc.) the overall vibration you will feel will be much larger than it otherwise would be.

Excellent advice, in addition to which I would add the importance of not stressing the frame with the engine. IOW, do not try to force alignment for holes that will not align and add shim (packing) washers into gaps between motor and frame. A stressed frame will vibrate like a plucked guitar string.

Alex and Magnetoman, thanks for the info. Re the 650ss, it vibrated much worse when I purchased it. It had been fitted with new rims and spokes as part of a complete restoration, done for the previous owner. The lacing job left a lot to be desired with run out of over 1/8" both directions on both wheels.

I have gone over things for tightness, but will check again.
Re the lineup of bolts and stressing of frame, this is something I have never checked and will definitely have a look at.
Unfortunately this bike has .060" over pistons which add considerably to the reciprocating weight. I see JS Eng now has lightweight pistons for 650 and 750 Dommies, these are said to reduce vibrations quite a lot. The cost is rather high as they have a different pin position and also require new longer rods.

Back to the BSA Super Rocket, I have located one which looks to be in decent shape and I was able to make a deal with the seller.

Piston weights can be reduced by taking away from under the crown. A machine shop with milling machine is best to do this. A lower compression piston is also going to be lighter and if your on standard bore, you may find that an original hepolite or bsa piston is lighter than some of the aftermarket units available today. It would also be better suited to the static balance performed by the factory.

Packing the frame correctly as per Alex is a must and makes a huge difference.

Super rockets (A10's in general) are quite smooth and vibration doesn't tend to be buzzy like the A65 but I have found them to be a much lower frequency and vibration is bearable.

A10's are great bikes...they won't have the power of a Vincent or the handling of a featherbed Norton but they are still excel in both categories. Really good all-rounders you can just get on and ride with a minimum of fuss.

The seller has taken the bike off his website, so this screen save is the only photo I have. I'll be changing the bars for something a bit lower.

Looks like a nice bike Glen. Although I always thought they looked a little odd with the small U.S.tank.

Looks like a nice piece of old iron, one of the last of 'em. '63. The old heap I had as a kid was a 62, great bike, had the TT carb and 10.5-1's in it, went very well. Never used it for touring though, only 'tonning'.
The flatter bars and a decent size tank will improve things, but more important stuff like sorting the brakes and lighting come first really.

Already found a 2 leader brake and complete wheel for it, $100.
The tank is next. I think I would forget to fill that little one often enough!
Too bad, the paint on it is very nice. I don't think it is the correct colour though. From my reading the 63 s only came in metallic red and the Sapphire blue on some earlier bikes was quite different than this blue.

Nice one,,,, The twin leader is a good brake, especially with proper asbestos linings not these modern 'green' garbage things. On my old one I just fully floated the shoes, it made it a bit grabby but improved the brake by about 250%. The old Dow fork bushes helped handling as the forks were always a bit long really and rigging a brace is a good move. The bloody cush drive nut used to undo itself on my one as well and chew into the primary cover, I remember having to devise something to stop that, but I can't remember what.
They are a lovely bike when sorted and a good 70-80mph all day long twin. Stick an oil filter on it as the old timing side bush has a reputation......

All the best
Nick

Glen,
I actually found those original bars quite comfortable, on my '63.

If you wish to sell them on, I might like to purchase them?
Got an A10 they'll go right onto...

Hi Brett

Once I get the old girl home I will try them out and maybe try some lower bars on there as well. If I do change them out, will definitely contact you here.

I'm arranging trucking now. The bike is 2,700 miles away!
Could have waited for a closer deal or a better deal but then figured the bike looked good and summer is here, what am I waiting for?
There doesn't seem to be all that many of these Super Rockets still around and I was really looking for a 61-63 ideally because of the various changes and improvements they came with.
Perhaps a fair number of the bikes have been turned into RGS Replicas and some into RGS fakes. Others have been junked. There are a couple being parted out on eBay.com right now, look to have been complete bikes, what a shame.
I suppose their vitals will live on in another A10 somewhere.

It looks like the total number of Super Rockets built in all years might be around 12,000, does that number sound about right?

My 1963 A10 was a good 'un. I found the high rise bars to make it extraordinarily comfortable to ride. I miss the old girl.

Would love to head over to OZ . 2018 gives me time to save for it beerchug

Thinking maybe those western bars just need to be rolled back a bit to look proper. Right now they are tipped way forward.

The size of the tank and the western style bars are great looking. Unless you plan on long rides, a larger tank isn't needed. That tank looks to be in great shape. Keep it.

I do some long rides but maybe this bike won't get used for those.

I have read that A10s get pretty good mileage, though that might be more so the lower tuned Golden Flash or even RR rather than the late 9 to on SR.

From reading original ads, BSA shows a choice of 3 gallon and a 4 gallon tank for the 63 Super Rocket. Then there is discussion on various forums of a two gallon tank. Any idea if this is a 2 gallon or a 3 gallon and which type of gallons those are?
3 Imperial gallons on a bike that gets 60 MPG would give a range of 150 miles with 1/2 gallon remaining for headwinds etc.

I guess 'beauty is in the eye of the beholder' eh? Gary E. I think they look like crap and a range of 110 miles or so is a bloody joke on any touring bike.

Yes--I agree--"beauty is in the eye of the beholder".
But to me the A7s and A10s always looked spot on with the 4 Imp gallon tank.
The US tank looks IMHO like a pimple stuck on the top of the frame.
Just my opinion--I guess other opinions are available---but of course are wrong!

Pointless wishful thinking on my part, but why couldn't those designers have come up with a larger tank with the same lines as the too-small to be practical export one?
