Maximum surmountable obstacle:
In this case, we have used the same wall of the previous test that came very well as it goes up very high gradually. The issue consisted from standstill up as high as possible using the gearbox and differential lock.
With the original cheap ATV tires were not able to overcome 54cm high, and that we forced the situation, so we got to fold the subframe and break the bumper. Once the front wheels increase the quad empanada on the wall, but this test was not climbing all the quad, if not just get up the nose.
Come to the turn of the Bighorn. We see the Kawa has won many degrees angle of attack, being very close to the ideal 90 degrees. This circumstance allows us to face ostáculos of any size, exceeding 81cm trouble, but they could have been more.
Once this 81cm, we were much fewer empanadas than 54cm before, giving the impression that would trigger a blow us up, but the lack of consistency of the wall did not allow us this test.
Now if we started and talked about a significant advantage over wheels 25 ??. With this bighorn, no wall can resist the moment we can raise the nose, which is the most complicated, the rest we’ll see how we do.
Step by rock:
We chose a stone with a vertical cut of about 50cm which we would face moving as we do when we go route or run a trial.
With the original wheels at low speed was virtually impossible to overcome, is more, it gave us the belly and a good part of leñazo that takes, left us with the rear wheels in the air. Finally with his run and hit rock gas and continue to overcome the route.
With 27 ?? , At first, we tried almost stopped, the quad ago by upload but excess tire pressure, it bounces, and we have to give up. In the second attempt, and with some inertia, climb the rock as if there were nothing and do not touch or with the belly or any other element of the Quad on the ground or the stone.
In this test, we realized that due to the greater hardness of the new wheels, the large diameter, and depth of the blocks, we can use much lower pressures without running the slightest risk of puncturing or desolate. Surely for extreme use, we can leave them in 0,20bar forward and not more than 0.25 back, gained much grip on all terrains.
The superiority of the bighorn in this type of land is more than evident. This is where you begin to take advantage of those great wheels
Step by complicated area:
We moved to a completely broken and full of stones sizable way. Half of it was a passage with difficulty with a good step in the rock and holes on both sides. It is a route you’ve spent a lot of times, but with original wheels, in a couple of places, the ATV falls empanada the broken and forces us to move to continue the march.
We continually hitting with low against the stones, in short, it is passed but with some difficulty. With 27 ?? things change, at any time the Quad touches anything, the holes are moved as if they did not exist and the two areas where before we had half trapped, are overcome with a slight stroke trigger. In the video you can see correctly, both paths are the same and yet with big wheels took us half to spend it on the other wheels.
Besides measuring only and exclusively the highest speed in both situations, our intention was that the acceleration also influenced the final result.
With as long as the development of new wheels, we knew that eventually the 27 ?? the maximum rate would be much higher, so we have sought a not very big straight in which more or less the Kawa reach its top speed and just finishing straight.
The result was very similar in both cases, with the original wheels were arriving at the end of the line at 105 km / h GPS. It is important to note that we are at 1,150 meters above sea level, and carburetion was not adequate.
With big wheels, we reached 106 km / h, but this time, the Quad still wanted to keep up speed to reach the final straight and having to cut gas. We can deduce that both acceleration and speed are not substantially affected if the maximum speed on long straights that lengthen the development can be somewhat higher than in the case of wheels 25 ??.
A curious fact is that in an unguarded moment I started to accelerate the reduction stuck and when the engine and turned to stop the GPS showed 70 Km / h!, In reducing, not bad !. I think it is necessary to install a kit motor drive to adapt to the new development. It is not normal in reducing us to get to that speed. We also see in the video surmountable step up as costs start climbing the wall in reducing, you need more force and less speed.
For trial tests with high difficulty and few books, these are the ideal choice. If the issue is very twisty and little room, maybe a smaller wheel is more appropriate.
