What is the main difference between a v twin motorcycle such as the honda rc51 and a regular flat 4 (gsxr1000)

V twin has two cylinders pointing in each direction.  On cruisers, V twins sound the best.\n\nIt looks like MotoGP is moving towards V twins.  Ducati recently unveiled a prototype.\n\nI had a V twin and now own an in line 4.  The in line four has much more torque at the top end.  The V twin seemed to pull better @ lower RPMS.

all depends on what you wish to do with it.\nAbout 20 years ago when i was into BMX racing , my choice of bike was the light weight "redline"

All the scooters I've seen are two-strokes.   Two-stroke engines are noisier than four strokes for two reasons.  Every other stroke is a power stroke in a two stroke, but only 1 in 4 on a four stroke.   The power stroke is the noisy one, because it's an explosion.   Secondly two strokes run faster than four strokes; up to 12 000 rpm, compared with 3 000 rpm.

Yes, several manufacturers make such motorcycles, they are called duel sport bikes.  Check your local bike shop.

a trail bike is for light trail riding, but a cross country bike is built with better suspension and as one might say a dirt bike otherwise, one may say one is more sturdier than the other but practically for the same purpose enjoyment, so enjoy!

I believe it goes something like this:\n1998 XC600 Big Block(*non VES) Wedge Chassis VES=Variable Exhaust System (power valves)\n1998 XC700 Wedge Chassis(*non VES)\n1999 XC600 Big Block(*non VES) GenII Chassis\n1999-2000 XC700 GenII Chassis (*non VES)\n2000 XC600 Small block(w/ VES) GenII Chassis -VES=More Power\n2001-2005 XC600 Small Block(w/ VES) Edge Chassis\n2001 XC700 Edge Chassis(*non VES)\n2002-2005 XC700 Edge Chassis (w/ VES)

Well I work at a place where we sell Specialized, so I'm biased a little. But ride all 4, in the same day, checking for the same things on every bike. The thing about bicycles is that the components that make the biggest ride difference(drivetrain, brakes, suspension, ect.) are made by somebody else and they are availible with whatever brand you want, the difference lies in frame geometry and materials. Everyone is different, everyone rides different. So figure out which bikes are in your price range, pick a sunny saturday or sunday and go bike shopping. Pick whatever feels best. Most brands/bike shops will offer a lifetime warranty on the frame, if they don't consider going somewhere else, and if you keep your bike tuned, regardless of brand, the parts will last a really long time(unless you ride real hard but that doesn't happen to too many hybrids).\n\nDon't forget wear a helmet, it'll could save your life. Ride on

Watch this video and you will see the difference, NOTE: The first race was just a late start by Jenson Button, so don't mind that. \n\nhttp://www.metacafe.com/watch/51275/fifth_gear_boat_vs_f1_vs_bike/

The only advantage is improved flat resistance.\n\nThe heavier tubes will increase rotating mass and actually make your bicycle performance lower, making it more difficult to gain and maintain speed.

Well, if you could just remove the small ring the gear ratios wouldn't be the same.  The "normal" gearing for a double is 53 / 39 and on a triple is something like 52/42/30.  If it were me, I'd definately upgrade to Ultegra.  But that's assuming money isn't an object.

well first off its MOTTOCROSS not motorcross. but its pretty easy. and if you get a good bike its gonna b expensive. but for a beginner you should get a yamaha 4stroke 250.

I have made and ridden motorcycles for 20yrs and the biggest factors with tyre sizes are stabilty from centrifugal force. Bikes with small wheels are unstable at higher speeds, they are inherently closer to destruction because at the same speed a smaller tyre is revolving faster. Tyres are critical on bikes. As a bike leans in to a corner, the tyre, because of it's shape or profile, increases in contact surface to counteract the amount of force pushing the bike to the outside of the corner. These forces get to a certain point before the bike will slide and crash. Things that affect the performance of this are, heat in the tyre, weight vs power vs tyre size, tyre profile, diameter, motorcycle geometry.\nBasically you do not change wheels or tyre shapes on a bike unless u are prepared for the consequences. Harleys may put really big tyres on but they are not performance orientated. \nAlmost all bikes these days have a 120/70 17inch front and depending on power a 160-200/55 17inch rear. Most bikes pre-1988 ran 18inch(or bigger) tyres. The simple reason for this is stability vs steerablity. 17inch is the best compromise. If you are designing a bike, stick with these sizes and work on suspension, geometry and weight distribution as they are more changeable. cheers Neil

Get a dual sport, not a sport bike, they're more upright. Cruisers are the hardest to learn.\n\nGo take the MSF rider training course (Motorcycle Safety Foundation) and you'll get a taste for it. Statistically you're much safer taking the course than learning yourself.\n\nI agree the shifting can take some getting used to. If you don't know how to drive a stick shift car, you should learn that first.

Obviously, the 700 would be quicker. I can't give you exact numbers tho. I can tell you that 60mph on a quad feels like 120mph, and they are not designed to be ridden that fast.

Santa Cruz is far superior.  The rear suspension design appears more efficient (lighter!) and I am certain the build quality cannot be matched by the new Trek (Fish-Trek-Bontrager-Klein.)\n\nTrek used to make fine bicycles in the 80's and early 90's, all made here in the US and most made by hand.  In the late 90's, they started making them overseas and by machine.  Go to a store that sells both and check out the difference in the welds.  \n\nIf it's a component thing, you can always upgrade later.  Hang on to the Santa Cruz.
