Gotta say I like the looks of that!

Not too sure about the downpipe, but apart from that it looks great!

Maybe a double wall to avoid bueing? ...looks very thick. Personally i like the discoloration on the header, particularly on stainless.

Looks like a wet sump design, didn't read about a counterbalancer.

BSA Gold Star 650 specifications revealed ; Published On Dec 04, 2021

Classic Legends was set up around five years ago, with the aim of reviving defunct, but once iconic motorcycle brands. The company brought Jawa back from the dead and is now doing the same with BSA and Yezdi. BSA Motorcycles has showcased its first offering, the Gold Star.
Gold Star has a kerb weight of 213kg (470 Lbs.)
To be assembled in the United Kingdom
Expected to rival bikes from Kawasaki and Triumph
BSA Gold Star 650: engine and gearbox
As we exclusively revealed back in June 2021, Classic Legends has prepared a big single-cylinder motor for this reborn machine. The 652cc engine is a liquid-cooled, DOHC, four-valve unit that makes 45hp at 6,000rpm and 55Nm of torque at 4,000rpm. BSA has said the engine “Torque starts building up from as low as 1,800rpm, delivering a healthy flow throughout the rev range and resulting in effortless cruising and bursts of acceleration when needed.” As we previously revealed, this new engine comes paired to a 5-speed gearbox.
BSA Gold Star 650: chassis
The Gold Star uses a tubular steel, dual-cradle frame and a 41mm telescopic fork and twin shock absorbers for suspension. Braking, meanwhile, is handled by a single 320m disc up front and a 255mm disc at the rear. The bike also uses Brembo callipers at both ends. The wheels on the Gold Star are 18 inches up front and 17 inches at the rear, shod with Pirelli Phantom Sportscomp tyres. The bike has a fuel tank capacity of 12 litres and a kerb weight of 213kg.
BSA Gold Star 650: expected price
The company has made it clear that it intends to start assembling BSA motorcycles in England by mid-2021. While it is easy to expect that the BSAs are going to be aimed at the Royal Enfield 650s, it’s worth remembering that throughout history, BSA has always placed itself above Royal Enfield.
Similarly, the new BSA motorcycle is expected to be priced higher than the Enfield 650s and closer to bikes like the Kawasaki W800 and Triumph Street Twin.

I'm guessing the 45 HP is measured at the crank not the rear wheel.

Pretty but under-powered and over-weight  :-\
No wonder we no longer have a motor industry

Who would leave his bike stock anyway. If you remove the elephant trunk of an header the pounds will go down considerably.

The KLR650 motor is a 650cc, 100mm x 83mm, liquid cooled 5 speed unit.
These folks list the KLR "Max Power" at 48 @ 6500 RPM, RW HP at 41.7, about 6 HP drive train losses, fairly normal.
KLR all-up Wet Weight is listed at roughly 420, which seems low. The KLR weight is carried higher up than the BSA's weight will be as it is a dual purpose machine.

The BSA 650 specs by Rush Lane say 45HP @ 6000 RPM, wet weight of 213Kg/ 470 pounds. 45/48=about 94%, so within 6% of the KLR power spinning at 92% or the KLR's crankshaft speed.

As Derottone clearly pointed out, the stock exhaust is likely made of lead/depleted uranium just like all quiet modern systems, which this forums participants routinely replace anyway at the drop of a hat. It's not unusual to see a 20-30 pound savings with an exhaust swap out. Quite possibly the BSA would end up within 20 pounds of the KLR's weight, with a lower CG, and possibly a bit better midrange. The KLR's are routinely lowered anyway by folks that either spend more time on the street or have short inseams. The BSA offers more "traditional" styling than the clean-sheet KLR. The old Yamaha SRX6 was a nod in the BSA's (Clubman) direction, as were the GB 500 Hondas, but never had an "Old School" appearing, purpose built powerplant.

According to AutoCarIndia the BSA will retail for about the same as the W800 & Triumph Street Twin, so around $9000 USD (7,000 Pounds). That puts it $2500-$3500 more than the 650 Royal Enfield. I'm guessing that the retail will drop a bit after the "me first" crowd thins out.

Is there one detail from an actual Gold Star anywhere on this machine?
 Nine grand for an Indian pretender, really?
 I am getting a little tired of what our Indian friends determine what cool is.
How about you? (Seen the Jawa?)

About the same horse power figures of my old DR650 it could hit an indicated 100 mph in stock trim

@ #12: Camaro? Mustang? Triumph? Norton? Lots of new clean sheet vehicles sold with implied old school "contact magic". It's all about available disposable income & mechanical aptitude. A REAL Goldstar has to be bid away from professional monied collectors and requires a lot of shop time, hand machined parts, love & money to be ridable on a regular basis. A clean sheet design with EFI & electric leg are godsends to us aged wards, "decal engineering" may be the best answer to an affordable, pretty daily driver. Like the 350 Meteor, 535 GT & 650 Interceptor, clean sheet but still good, fun bikes. Indians can run the potential sales numbers/brand appeal pretty well, hopefully they didn't drop the ball designing the new BSA.
