The difference was the extra stopping power. ABS does nothing to prevent a rear wheel lift. It doesn't even function when the front wheel is going under 3mph so you can get the rear wheel well up in the air and the end of the stop.

Nice write up...

Now the real test I would love to see is a bike similarly setup with 4 pots vs 2 pots. For me when it comes to replacing / upgrading parts on my motorcycle I follow the same rules I follow with the car I rally.... until the stock part breaks use it until it does | there are noticable exception such as HID upgrades so don't bother point that one out anyone hehe

Still good to know this upgrade is possible with what appears to be little fuss

I'm usually the same way, but the 4 pot upgrade is a vast improvement in stopping power and general brake feel compared to stock. Well worth the $80ish I spent to do it.

I gave $50 + shipping for mine. Seemed reasonable. The seller was asking $59.95. I did tweak the left hose a bit to create some slack. Didn't take much...

I did a couple of 90kmph (55mph) stop tonight with ABS activation and without. Everything worked fine and braking was stronger with less applied to the lever. Without ABS activation (threshold braking) I was surprised at how quickly the brakes reacted and how strong the brakes felt. With ABS activation the brakes worked well and still very strong braking. I did noticed at the very end when the ABS activation quites (under 5mph), brakes grab and want to lock but this occurs when your almost stopped. I also tried the brakes on a gravel road at speed of about 30mph. At that speed I grabbed a handful of front brake and applied the rear hard. ABS activation was normal without any drama. Seemed to work exactly the same as before. The more I ride with this setup the more I like it. The brakes react very quickly when you want them to but are still easy to modulate. I do expect a shorter stopping distance because of how quickly the brakes come on.

Just scored some 4 pot Nissin calipers off eBay. 2005 f4i with 5k miles. $82 with the Honda master. Will order the brackets soon

Also, Is it necessary to change out the M/C or will the stock suffice?

Try it and see. Some owners feel the stock 2007+ M/C makes the lever too mushy and prefer the older one with the larger bore.

I'm a bit on the fence after reading this: http://www.vstrom.info/Smf/index.php...,11089.90.html

Interestingly, if M/C piston size is an issue, my set comes with the Nissan M/C from the F4i, which may work for the Wee. Based on the afformentioned thread, i'm wondering if the mod is safe to do with the ABS system.

Hi, You are right in your observation that the 4 Piston Brake Calipers have increased your stopping power and you are now easily able to brake right up to the point of threshold braking. Your brakes are working well based on your comments.

Most bikes with good brakes, abs or not, will lift the rear wheel slightly for a moment when the brakes are applied with progressive force. This is a function of the weight and traction transferring forward. Not to worry at all.

Enjoy the ride, and best regards,
Blair
