Video Transcript for Master Lock Vehicle Locks - Motorcycle Lock - 8304DPS Review

Today we are going to show you part number 8304DPS. What we have here is a 3 inch disc brake lock from Master Lock. What this lock is designed to do is prevent roll away theft and basically it goes on the front disc brake on your bike. It prevents your wheel from turning so you can not just roll it away. It is pretty easy to use. You just slide it over the disc brake and push the button down and it automatically locks itself into place. It comes with a bright orange cord that runs up to your handle bars to remind you that it is still connected to your bike. We will go ahead and cover some of the fine points really fast. This is the cord we were just talking about it stretches out from the fork all the way to your handle bars. This is the lock itself. It is pretty easy to use. What you do is turn the key and the pin comes up and your rotor goes in there.

Just slide it on and push the button and it is secure. It comes with a couple sets of keys and also a nice carrying case that you can put it in when you are not using it. That way it does not bang up anything in your cargo area that you have it stowed away with. Plus it comes with a little buckle too if you want to tie it off to something else. Installing it is pretty simple you slide the cable over one end and the other half goes around the rotor. Then you take the key out and push the button shut. The other half goes up and connects to the handle bar to remind you that it is hooked up. Once of the nice features of this lock is you do not have to worry about locking your bike up to a post or stationary object. This way it can not be rolled away or anything like that. There you have it for part number 8301DPS from Master Lock. The 3 inch disc brake lock.

I had my bike stolen a couple of weeks ago, cut the cable off with bolt cutters ! This lock system will be a big help in slowing the thieves down , since it can’t roll . Looks like a good product , I will use it with other systems , hope not to lose another one ! They’ll have to carry it off ! 853189

I was having a hard time finding a Disc Lock locally and so I went on-line to see what I could find. etrailer not only had exactly what I was looking for, but the price was great, and I got a name brand (Master Lock) product. The bright color and lanyard help prevent "forgetting to remove before operation" scenarios while the fit and smooth operation are a real plus. I highly recommend both etrailer and this lock. 825287

Lock cylinder is a little tricky. WD-40 it often and light pressure when inserting the key and turning seems to work better. Comes with a case for traveling. Good product for the price. Shipping was fast with no problems. 686638

Love this disc lock! Almost bought the one from Harley for twice the price. Decided to shop around....googled it and this lock came up.....reviews rated it really well. Arrived sooner than expected and was kept up to date in terms of tracking. Packaged very well, feels sturdy and well made. Fits on my 2015 Ultra Limited Low nicely and the reminder cord is a nice addition as well as 3 keys and a storage pouch. Really happy with etrailer.com. Highly recommend! 569586

Haven't used yet, but appears to be a good product. Sturdy and solidly built. Not sure if the cable is going to be long enough to reach from the lock to the handlebar on my bike, but the storage bag included has a strap and buckle on it, should be able to put that around the throttle as a reminder to remove the disc brake lock. 198671

Ask the Experts about this Master Lock Vehicle Locks

  • What Brake Lock Will Work With a 2012 Honda Shadow Spirit With Spoke Front Wheel
    To determine if the Master Lock 3 Inch Disc Brake Lock, part # 8304DPS will fit your 2012 Honda Shadow Spirit you will need to take a couple of measurements. The lock pin has a diameter of 0.40 inches or slightly less than 7/16 inch, so you first need to measure a heat dissipation hole on your rotor to see if you have an opening that will fit a 0.40 inch pin. Next, measure the distance from the outside edge of your rotor to the center of one of the heat dissipation holes and if that...

  • Disc Brake Lock # 8303DPS Recommendation for a 2006 Honda Reflex Scooter
    I would go with the 3 inch Disc Brake Lock by Master Lock, part # 8304DPS. The rotor on your 2006 Honda Reflex while small in diameter, has a fairly wide brake pad surface area, and I think it would be easier to use the 3 inch # 8304DPS as opposed to the 2 inch Disc Brake Lock by Master Lock, part # 8303DPS. I attached a link to video that demonstrates how this product would install on a motorcycle.

  • What Is The Max Disc Thickness and Extended Cord Length Of The Master Lock Disc Brake Lock?
    I pulled the Master Lock Disc Brake Lock, # 8304DPS, for you to measure it. Here are the measurements you requested. Height of lock over disc is 3-1/16 inch to outermost part of lock.

I've attached a picture for you of these measurements.

  • How Secure is Street Cuff Motorcycle Security Lock 8290DPS
    Any lock, no matter how robust or complicated, can be defeated. The mere presence of a lock and/or the fact that specialty tools would be required to defeat a lock would mean that a would-be thief would likely move on to an easier target. The Street Cuff lock # 8290DPS does its job well and the likelihood of a thief walking around with bolt cutters or similar tools is very low making the security of this lock high. An even more secure option is a disc brake lock. We have a 3 inch...
