If they were antiquated, then companies with cutting edge racing bikes would not be using them. Plus you can hit the throttle sooner in corners and power out where with an i-4, if you're running in the powerband, you have an overly twitchy response to sudden throttle.

The Porsche designed V-Rod is hardly antiquated, like it or not, either.....
But, going into corner is nice too......more controllable into the apex. Nice engine braking.
It strange only guys who've never ridden twins/HD's are their loudest opponents.
Some people think a Lexus is a sports car and some think an AC Cobra is.
I want to feel machinery when I ride

Around tracks, where racing takes place.

Point is, they're still being developed and still completely competitive with other types of motors.

2000 Honda RC51 engine

- Prodigious power is produced across a broad engine-rpm band, peaking with 126 bhp at 9000 rpm and 75 lb./ft. of torque at 8000 rpm in street-legal trim. Redline is at 10,000 rpm

- 999cc DOHC eight-valve 90-degree V-twin engine is specially designed to withstand the rigors of Superbike competition.
- Centrally mounted ram-air intake duct routes cool, pressurized air directly through the frame's steering head structure to the 10-liter airbox, improving intake efficiency while slimming the aerodynamic profile. The ram-air duct doubles as a front cowl stay, shaving 12 ounces off of a conventional mounting system.
- Each cylinder head features large, 40mm intake and 34mm exhaust valves with a 24-degree included valve angle. This provides a short, direct path for the air/fuel charge entering the combustion chamber and results in high power output.
- Gear-driven camshafts utilize three-axis drive gears to maintain accurate valve timing and durability at sustained high engine speeds.
- Innovative head gaskets minimize distortion caused by head bolt tightening, improving sealing performance and maintaining combustion pressure for consistent high power output in competition conditions.
- Direct shim-under-bucket valve actuation system ensures high-rpm durability, and allows 16,000-mile valve maintenance intervals.
* - High-pressure programmed fuel injection (PGM-FI) delivers fuel at 50 psi to two injectors per cylinder, mounted opposite each other in huge, 54mm throttle bodies. Fuel is delivered through four nozzle tips in each injector, producing a very fine spray and a highly combustible air/fuel charge for maximum combustion efficiency and power output.
- Cast aluminum pistons are screen-printed with solid LUB-Coat finish to minimize friction between the piston and cylinder wall.
- RC45-inspired aluminum composite cylinder sleeves are high-pressure-formed from sintered aluminum powder impregnated with ceramic and graphite. The lightweight composite sleeves provide better wear resistance and superior heat dissipation compared to conventional sleeves.
- Nutless connecting rods feature bolts threaded directly into tapped holes in rods. Design is lighter than conventional bolt-and-nut combination. Carburized rods provide strength and durability under high loads.
* - Crankshaft center lubrication system carries oil to main and connecting rod bearings through passages in the crankshaft as well as conventional journals, allowing lower main gallery oil pressure and a smaller oil pump design, consuming less horsepower at high engine speeds.
- Electronic CPU provides digital 3-D fuel injection and ignition maps for each cylinder, creating ideal fuel mixture and spark advance settings for maximum power and throttle response.
- Iridium-tipped spark plugs require less voltage and maintain ignition performance in demanding conditions.
- Side-mounted dual radiators utilize low pressure of airflow passing over outer surface of cowling to draw air through from the inside. Side positioning allows optimal placement of engine for low center of gravity and superb handling and permits flow of air to reach cylinders and exhaust pipes for enhanced cooling efficiency.
- Aluminum water pump.
- Air-cooled aluminum oil cooler.
- Magnesium head cover, clutch cover and left rear sprocket cover.
- All-stainless two-into-one-into-two exhaust system with two 5.3-liter canister-style mufflers featuring a buffed finish.
- New seven-plate clutch design is compact and tough, featuring durable friction plate material.
- Smooth-shifting close-ratio six-speed transmission features ratios carefully matched to the engine's power band.
- Durable #530 O-ring-sealed drive chain.

My DR650, with a whopping 40hp single, was the most fun on a bike
Ive ever had. The Torque of big jugs is

I had a 2s, 150cc, 4sp scooter, and I laffed when the punk rockers who dropped it
off said I would have problems riding it at first....I pointed to my shed that held
a Zx-9 and the Softtail and said "yeah, r i g h t " But, WOW...
they couldnt have been righter ! I could barely balance it at first after the MC's.
But later, when I was comfortable with it, it was a blast. IT would top at
60mph, but that 60 felt like 145 on a sportbike Fun '0 Plenty !

That was probably one of the best things I've ever done to help with my skills as a rider.
Rain is not too bad. However, fog or drizzle bring up all the oils out of the road. After it's been raining for a little while it's pretty nice.

I don't ride motorcycles, and I have a dumb question.

How is it that a single motorcycle frame can fit such a huge range of rider heights? It seems that really short or really tall riders would make compromises compared to the average, whatever that is. For example see Pedrosa and Rossi below:



Rossi looks like his weight is shifted more towards the rear. Pedrosa would seem to be at a disadvantage; being smaller, he probably can't muscle his bike as much as Rossi. (Have we ever seen Pedrosa do an epic save, a la Edwards or Rossi?) Despite his size, Pedrosa is competitive, and yet you don't see many riders of his ability and size come out of the smaller displacements.

Blame it on the MTVization of Motorcycling.
The Biker Boy generation doesnt have the patience or
mental fortitude to learn to 'ride'. Flying down I-95 at
130 on yer stretched 'n lowered R1 has replaced getting a 250 and
riding the wheels off of it before you moved up to a 550 or so......

Motorcycling, like bicycling, attracts a large percentage of idiots. But bicycles, which generally don't go 100+ mph, are safer.

Any yet all my e-room trips in the last 20 years have involved bicycles.

Techically speaking my Ducati ST4s is an L-twin.

Adjustability of stuff like seating position, foot peg position, and handlebar position. There's also not a lot of muscling involved. Most movement takes very little input. To turn left, you push on the left handlebar and the bike will go with no real effort. And if something like a tankslapper were to happen, the best thing to do is let up on the bars and let it ride itself out. Trying to muscle out of one of those could have the rest of the bike wobbling back and forth in no time do to the transfer of the force through the rider's arms and into the rest of the bike.
