    Shell construction utilizes a highly advanced molding technology with a multi-composite combination: uni-directional carbon composite with aramid layer that gives significant radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy, and providing critical penetration protection
  • This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management; limited outer shell deflection means the energy spreads wider and is better absorbed by the EPS liner
  • The Supertech M8 liner construction combines with the shell to offer highly efficient impact energy management
  • Formed with a multi-density EPS polymer, the energy absorbing layer gives an inner helmet profile which soaks up forces dissipated over the outer shell at the point of an impact and provides a shape offering a close and comfortable fit
  • Four section liner construction allows for specific densities of polymer to be prepared for different zones around the helmet lining improving energy performance, comfort and fit
  • A-Head fitting height and angle adjustment system
  • Incorporates a system to allow the helmet to be tuned exactly to the rider’s preference for the height and angle at which the helmet sits on the head allowing for ultra-specific set-up that can be adapted for the type of riding and the rider’s preference
  • Raise and lower helmet fit and tilt with micro-adjustable pad
  • Visor release system ensuring the mounting is held securely in place for riding over extreme terrain and any track conditions
  • Visor release system provides the right level of resistance to ensure the visor detaches from the helmet shell if it is subjected to a significant impact regardless of angle
  • The Supertech M8 visor release mechanism is conceived to avoid the inherent weaknesses in other types of anchoring systems
  • Maintaining shell integrity is vital for safety and with the possibility of multi-directional forces impacting on the visor, separation at the critical point of leading reduces potentially damaging leverage and rotational accelerations that refer injury to the rider’s neck and spine
  • The base of the Supertech M8 helmet has been sculpted to give a relief section, where the bottom profile is raised to clear the collarbone (clavicle) Energy absorption pad incorporated into the area of the base pad where it sits over the rider’s collarbone
  • Energy absorption pad consists of a more flexible compound rubber section which allows deflection when it contacts the clavicle
  • Polypropylene chinbar allows for a degree of lateral deflection, further improving impact protection for the collarbones
  • Multi-Directional Impact Protection System (MIPS®) incorporated to reduce rotational motion energies that impact the helmet causing damaging gyration force to be transmitted to the brain
  • A low friction ‘slip’ layer is incorporated into the Supertech M8 helmet, between the comfort padding layer and the multi-density polymer energy absorption shell. When energy is impacted upon the helmet, causing a rotation force, the MIPS layer allows for movement of the inner absorption layer to damp and re-direct the energy before causing significant acceleration stress to the brain. This mitigates the causes of brain injuries, such as concussion
  • Emergency Release System (ERS)
  • While the helmet is still on the rider’s head, the side cheek padding can be extracted efficiently and safely to allow ease of removal by trackside support and medical staff
  • The Supertech M8 is also designed to allow a helmet ‘Eject’ inflation system to be fitted into the inside crown of the shell
  • Along with the ERS padding removal, ‘Eject’ allows for emergency removal of the helmet, without putting load on the rider’s spine
  • Chin-strap: Wider than certification requirement: 26 mm for comfort and produced with a woven poly yarn to give a soft ‘hand’ feel that connects securely with a double D-ring
  • The material selection, preparation and construction of the helmet has been rigorously analyzed for weight to strength and energy absorption properties and a strict analysis of all the components used in the Supertech M8 finishing

Works well. You need to drill a 3/8” hole
Appears to be well made, alignment bar slides in nicely. As stated, you need to drill a hole in the bar for the gimble bearing driver, the directions are not clear, what I did was before I take out the old gimble bearing, put an O ring on the bar close to the last step on the bar, slide the bar all the way in, then carefully slide the bar out, this marks the distance from the back of the gimble bearing to where the shaft on the outdrive bottoms out, move the O ring a 1/4” towards the stepped part of the alignment tool (this is so you won’t bottom out the alignment tool when driving the gimble bearing in) then slide the driver puck up to the O ring and use a 3/8” diameter transfer punch through the side hole in the puck to mark the bar. You need to drill a 3/8” diameter hole in the alignment bar, two V blocks, some clamps, and a drill press will make drilling much easier, after the bar is securely mounted and centered in the drill press, use a center drill, then 1/4” drill first, using plenty of oil, drill all the way through, then use the 3/8” drill, deburr both sides and you should be good to go. People complain that it doesn’t come pre-drilled, the reason is that not all out drives are the same so you have to fit it to the outdrive that you have. Fortunately, I have a machine shop at my house and have a jig setup with various drill bushings, but the method I described above should work for you. Just make sure you’re perfectly centered and secure before you start drilling.

A must pull your gimbal bearing
You do need to drill a hole but worked perfect

Worked for Volvo Penta SX Gimbal Bearing
Very heavy tool, I was surprised. Pulled my bearing like it was nothing. Putting the new bearing in was a little more difficult as you have to drill a hole in the engine alignment shaft where it will work for your particular outdrive. Not hard, but it does not come pre-drilled as the required depth for each particular gimbal bearing differs by manufacturer and model. Measure your bearing placement before removal and check that it was installed correctly in the first place. The bearing should line up with the grease fitting and the o-rings on the drive shaft should end up riding in the middle of the bearing. once you have your measurement drill the hole, I used a drill press. I suppose you could use it on multiple outdrive models as long as you can drill more holes.

Great value
This kit worked perfectly on my Alpha one mercury outdrive. I saw a lot of people mention that it was a hassle to drill the hole when you better have all this alignment stuff. I threw it in use my regular drill drill guide and then the second hole was lined up. Pulling Gimble be very easy. I did have to adjust it up at an angle because my bearing was sitting in their crooked and it came out the second time I made the adjustment to the angle. I would highly recommend this.

Unfinished product - doesn't work - waste of money
in order to use this as an installation tool the directions tell you to drill a hole through the 2 inch steel rod..... either this hole should already be drilled, or this should not be advertised as an installation tool..... it will not install any bearings without extensive modification and requires the use of a drill press or a lathe. very dissatisfied that I now have to buy ANOTHER tool just to finish this job because this one doesn't do what it's described to do.... piece of junk... typical amazon garbage.... this is why I haven't used amazon in over a year... they rip you off with garbage.... I should have known better .... don't buy this junk .... Now they say 20 -30 days to get my refund .... Don't waste your time
