STR vs. SCR: How To Decide Between Them

STR stands for Street, and that defines the mission: cast wheels with Pirelli Angel GT tires, a lower and narrower handlebar, a sportier riding position, and a smaller windshield instead of the SCR’s flyscreen.

The STR asks for more active cornering—more pressure at the handlebar and more input through the footpegs. The SCR’s upright riding position encourages a more relaxed approach. This is not a difference in quality, but in character.

Switching to the SCR makes it feel taller even though both models officially have an 810 mm seat height, because the SCR handlebar changes the rider’s perceived posture. The STR is therefore the more compact and sporting motorcycle on pavement, while the SCR is roomier and more relaxed on mixed surfaces. Riders who stay exclusively on asphalt and prefer active riding should choose the STR. Riders who occasionally venture onto gravel and want more relaxed touring ergonomics should choose the SCR.

Engine: Identical to the SCR, With Revised Mapping

The liquid-cooled 649 cc DOHC parallel twin is the same unit used in the SCR. It traces its roots to the Kawasaki ER-6 engine, is manufactured by Zhongneng/CFMoto, and uses revised mapping compared with the X-Cape. Output is 61 hp at 8,250 rpm and 54 Nm at 7,000 rpm. A six-speed gearbox, chain final drive, and Euro 5 compliance are standard. There are no riding modes and no traction control.

The engine does not enjoy extremely low revs. It becomes pleasant from around 2,500 rpm. Accelerating in fourth gear, it feels surprisingly lively. Its sweet spot is fourth and fifth gear at roughly 4,000 rpm—enough for an easy 100 km/h and for strong roll-on acceleration without constant shifting.

Thanks to its balance shaft, the twin remains free of intrusive vibration throughout the rev range. Above 8,000 rpm it becomes mechanically noisy. Bosch fuel injection is direct and well calibrated, without an imprecise rubber-band feel. The six-speed gearbox shifts exceptionally smoothly.

Chassis: Fully Adjustable KYB, Sporting Geometry

The 43 mm KYB USD fork provides 120 mm of travel and is fully adjustable for preload, rebound, and compression damping. The KYB monoshock uses direct mounting, also provides 120 mm of travel, and offers preload and rebound adjustment. A tubular steel frame works with an aluminum swingarm and a 25-degree steering-head angle. The STR responds smoothly to pressure at the handlebar and additional input through the footpegs, willingly swinging through corners. The suspension also performs convincingly on poor pavement, absorbing cracks, edges, ruts, and potholes.

Brakes: Brembo Two-Piston Calipers, ABS Intervenes Late but Strongly

The brake system is identical to the SCR: Brembo two-piston floating calipers on twin 298 mm front discs and a single 255 mm rear disc. Bosch 9.1 MB ABS cannot be switched off. It intervenes relatively late, but then very securely and decisively. The source cites Rider Magazine as judging the front brakes good despite the two-piston layout: the fork does not collapse under panic braking and the bike does not stand up dramatically when braking at lean. For a naked bike in this class, the system is entirely adequate; there is no need for an ultra-aggressive radial-caliper supersport setup.

Ergonomics: 810 mm, Sporty Naked-Bike Setup

Seat height is 810 mm, identical to the SCR on paper, but the STR feels slightly lower because of its narrower, lower handlebar. The naked-bike riding position is upright but active, with the upper body leaning slightly forward and the footpegs directly beneath the rider. At 810 mm, the Seiemmezzo is also accessible to shorter riders. The small windshield provides modest protection, while a larger screen and luggage solutions are available through Moto Morini. Riding with a passenger is possible.

The STR runs Pirelli Angel GT tires on cast-aluminum wheels, 18 inches front and 17 inches rear, in 120/70-18 and 160/60-17 sizes. The Angel GT is a sport-touring tire with a broad asphalt operating range, offering more precision at speed than the SCR’s MT60RS, though naturally it is not intended for gravel or enduro use. Backlit handlebar controls, a 5-inch color TFT with Bluetooth, and USB are standard.

Stationary Noise, Fuel Consumption and Range

Stationary noise is 92 dB(A), below Tyrol’s 95 dB(A) limit. The engine produces a sonorous note that becomes almost cheeky under hard acceleration. Fuel capacity is 16 liters. Official consumption is 3.8 L/100 km, while a realistic backroad figure is around 3.5 L/100 km. That gives roughly 420–460 km of range. Moto Morini quotes a top speed of around 170 km/h.

Price and Positioning

The German price is around EUR 7,299, making the STR slightly less expensive than the SCR at around EUR 7,699. The difference reflects the SCR’s more elaborate cross-spoke wheels and scrambler-specific equipment. A Kawasaki Z650RS is around EUR 8,500, a retro naked with related Kawasaki engine lineage. The Honda CB650R is around EUR 10,000 with 95 hp and E-Clutch, while the Yamaha MT-07 is around EUR 8,500 with a 690-class twin and more power.

The STR positions itself as a fully developed middleweight naked bike with Japanese components at a price below much of the European competition.

Verdict

The Moto Morini Seiemmezzo STR does exactly what a naked bike should: it flows smoothly through corners, brakes cleanly, and uses a vibration-free parallel twin that makes no attempt to hide its Kawasaki roots. The brakes are sufficient, the suspension convincing, fuel consumption low, and stationary noise Tyrol-compliant. Riders who stay on asphalt and prefer active riding should choose the STR. Riders who occasionally want gravel under the tires and a more relaxed riding position should choose the SCR.

Quick Check

+ Happiest around 4,000 rpm in fourth/fifth gear; strong roll-on performance without frequent shifting; suspension remains convincing on poor pavement.

– Brembo two-piston floating front calipers rather than radial units; ABS responds late and then strongly; ABS cannot be switched off.

– No riding modes or traction control; engine dislikes low-rpm lugging and becomes mechanically noisy above 8,000 rpm.

– Short 120 mm suspension travel front and rear; no gravel reserve, intended for road use.

– Small windshield is not adjustable; no standard navigation; Moto Morini dealer network in Germany remains limited.
