Since the 2021 CBR1000RR-R Fireblade SP was announced in November, we’ve been eagerly waiting for  Honda to release horsepower figures for the U.S. market, hoping it wouldn’t be far off the 215 hp claimed for the European-spec model. Thanks to VIN documentation Honda submitted to the National Highway Traffic and Safety Administration, we can now report the American-spec CBR1000RR-R will only produce 188 hp.

Without a doubt, the biggest news in the sportbike scene for 2018 is Ducati’s Panigale V4 and the emergence of a mass-produced four cylinder engine – the Stradale V4. While Ducati has finally left its beloved V-Twin engine behind (at least in terms of superbikes), there was no way the folks in Borgo Panigale would conform to tradition when it came to its new four-banger. For starters, as the name implies, the new engine is arranged as a 90º V4 – essentially multiplying  its V-Twin tradition by two.

I read somebody’s theory a while ago about why we never hear from distant planets: About the time we learn to broadcast into space, we also learn to build nuclear weapons. So by the time we’d hear from Tralfamadore, 200,000 light years away, it’s already toast and so will we be.

You’ll remember we, okay I, first rode Indian’s new Scout Sixty last November, where we laid out the differences between it and the regular Scout. Besides a substantial reduction in price to $8,999 and the doing-away with of fifth gear, the Sixty gets, “a simple sleeving down of the bike’s excellent liquid-cooled 60-degree V-Twin, from 1133cc to 999cc (69 to 61 cubic inches)… accomplished with 6mm slimmer bores, down from 99 to 93mm diameter. Stroke remains 73.6mm, meaning this is still an oversquare Twin that doesn’t mind using its 4-valve DOHC heads to rev smack into the 8200-rpm limiter now and then if you so desire. Compression ratio for the smaller engine is a bit higher; up to 11:1 from the 10.7:1 of the 1133cc version.”

At both the unveiling and riding introduction of Triumph’s new Street Twin, the manufacturer noted that the new 900cc engine made more torque – and at lower rpm – than the previous 865cc mill. At the riding introduction, Triumph expanded its claim to include the Street Twin producing less peak horsepower than the previous, smaller engine. So, imagine our surprise when we actually get our sweaty mitts on a production model Street Twin and dash it over to our local dyno shop – and learn that the new engine makes both more torque and horsepower than the most recent dyno run we have of the old 865cc engine.

I felt as giddy as a kid at Christmas when I heard Yamaha’s new R1 was prepped and readied for MO’s home-soil evaluation. We already knew it was ready to challenge the best of the best – our Troy Siahaan came back from its launch raving about how the R1 is resetting the bar in the stupefyingly magnificent superbike class – but I was anxious to find out for myself just how impressive it is.
