Assuming you operate within the load limit (found in the manual), increase the spring preload on the suspension, and just be ready for the bike to handle way differently. Increased care should be taken, especially at low speeds and during turns and stopping. Make sure the passenger knows that what they do will affect everything, so no big head movements or wild leaning on their part.

The passenger being aware that they will affect the bike is a must, so the smarter they are, the better.

hrmm...ill admit, poor question on my part. ill revise. what kind of performance effects do you feel the worst effects. such as, freeway merging, braking. just a generality on how much more brake are you applying etc. the more i think about this the more i feel its a lame question lol.

Well, there's more weight on the bike, and more of a load on the motor, so acceleration suffers. The fact that there's more weight means it takes longer to stop. More or less, every aspect of performance and handling suffers.

I'd say the most important one that suffers is braking.

Depending on how much experience you have, you may want to think twice about it, particularly if the passenger(s) are going to be squirrelly girls that you meet at various places.

I've been riding motorcycles for a long time, and I have a no passenger policy that I never make exceptions for. Most potential passengers just can't be trusted, way I look at it. But that's only my

I've ridden with my girl on the back, but she already had pillion experience. She's about 5'8", 110lbs.

I have to keep telling her to squeeze me harder with her legs, otherwise I can't even tell she's there!!

I'll never pillion anyone else. My next bike will be a solo seater (cheaper rego), so I won't have to worry about people asking.

Good advice so far. Pay close attention to the stuff sidewaysducati posted in his second reply.

For a big guy on a 600, you need to pay close attention when carrying a passenger. By yourself, you load the bike pretty good. You may want to break out the tape measure and record some suspension settings (preload mostly) for riding with a passenger. This will help keep the chassis most sorted for the amount of weight. As you go along, you can adjust your damping settings to your tastes. If you keep track of "alone" and "passenger" settings, you should have no problem with the suspension running out.

As far as power goes, I can't help. Both my bikes are 1000s, and I have an absolute no passenger policy on the YZF. On the FZR, once I have the suspension set for a passenger, I generally can't tell they are there, but I know that I unconsciously adjust my riding.

Hope this helps....

As far as a 600 goes, it will have plenty of power for 2 but will suffer somewhat with slower speed power and around town torque. Hills will also be more of a challenge. If you will ride two-up alot, something bigger than 600cc would work a little better. Just my 2cents.

When riding hills, you just have to be mindful of dropping a cog or two to keep the revs up in the torque end of the range.

My girl and I use the ride a 40hp ZZR-250 up many a mountain range near our home, always doing at least the speed limit.

But yeah, as most have said, you can't beat cubes...

The springs in the fork tubes are for an average weight person, which in Japanese manufacturing is about 160 lbs. I weigh 192, and had my forks and the shock reworked by Race Tech. New springs for a heavier person were used, along with new valving and different viscosity oil. It makes a difference. On yours you need to adjust the preload, check your owners manual for guidelines.

The passenger will affect weight transfer front to rear on braking, so when you do turns brake more gradually to prevent excess nose dive and weight shift to the front.

Have her hold you with her arms around your waist and hands locked together if possible, you will notice that more.

That's a very uncomfortable position for pillions, being squeezed up against the rider. Helmet clashes are a p.i.t.a. too.

I used to offer for my girl to hold onto me or my jacket, but she felt more secure holding the rear handle, especially under brakes. Her shoulders would get a bit sore after a long ride though.
