I think last I looked a stock 500R has like 63HP, and somewhere around 45ft/lbs of torque.

but you add a full exhaust, air intake, and rejet the carbs and you just added 20% at least to your power.

that is what I've done. Jardine full exhaust, K&N air intake, and some much bigger jets in the carbs.

ask triplesecman about it too, he has a 500R, all stock.

The 500R is forgiving enough not to kick your butt, but it has enough power to keep you happy for years to come. I bought my bike and took it home and learned to ride, never stepped on one before. Thats why I recommend it to people so much, we did the same with triplesecman, I rode his bike back to my house for him and showed him the basics and send him through the parking lot wars for a day or so.

I would have to disagree with the post above.... See for me I would not want to have to sell the 500r in a year because thats what your going to want to do once you get the hang of riding it.. The difference in the 500r and the 6 is tremendous.. I know that for a first bike you would be afraid of the power but, you will get used to it real quick... Plus you will not get back the $$$ that you want when you sell the 500R.. Just my thoughts...

Specifications subject to change without notice, and may not apply to every country.


From memory the US model has air injection into the exhaust to pass emissions, the californian one has some evaporative emissions control system. The electrics are slightly different on the US model (headlight on all the time and extra circuit to switch it on when bike is started).

I have been told that some European D series have twin front disks (I have seen a french one that did) but the UK one as far as I know did not until around 2000 (when it became the E series ???)

The EX500A was similar in terms of the engine, it had a 16 in. front wheel, different forks, and a rear drum brake. Front disk on Left rather than the right. Other than that I belive most of the differences were cosmetic.

I believe the number of teeth on the sockets have changed once to twice which would alter the ratios.

I hope I have not made too many typo's in that lot ;-) Its my first post be nice :)

Oh yeah, hi to everyone :)

Ride safe. Chris

ARGH! Its stripped out all my tabbing, you guys can work it out I bet :)
