Finally my PR4 240 review. I am a 43 year old rider, 1.67 m. living in Belgium. Riding here is different than you have. Frequent we have to ride a street section when going fro m one offroad to another. We have a variety off terrain to ride in. Sand, mud, rooths, stone both uphill and downhill sections. Mosty not that long uphills but sometimes very steep and technical. It has some delay because I wanted to have some miles done before writing the review. My bike has approx 1000 km on the odo meter.I have used it in varoius terrains and weather conditions. Do I like the bike ? Yes I really love it. In am not an enduro racer, I ride for pleasure and like the technical stuff more than full throatle speed. I used the bike on singletrack, fierce decends and off course difficult uphill sections. My bike is equiped with a Michelin x11 trials tire in the rear. It has also the fatty,higher steer and rizers from ajp performance. Further improvements are Bendix rear racing pads. The bike has the racing exhaust and all catalyc/environnement stuff removed. I sports a 112 main jet. Standard gearing on my bike was 12-48 . This is for riding trial like sections. Engine is almost unstallabel in that configuration. Because most friends ride the Husky and orange brand enduro bikes I changed my gearing to 13-44. Top speed off 94 km/h now. When a more technical rode is presented I can easily swap the front sprocket to a 12 and get instant torque again. I opted for the adjustable Sachs rear suspension. In the front I went with the standard marzocchi. in Belgium you have the choice between this one and the Sachs 48 and Marzocchi 48 extreme fork. I had a difficult choice between the Sachs and the Marzocchi. When I had made my test run , i really liked the flush but stable feel the standard marzocchi offered and went with that one. How I feel this bike is riding? My other bike is a wr125 jetted an powervalve tuned for max torque ( Walt silver spring) when comparing the two bike I feel much more confident on the Ajp. I have a lowered seat on the wr. Saddle height now 915 mm. The Ajp is same height, but I get better sag values and off course this is giving me alower seat height. Fork springs in the wr are standard and too heavy for my weight 70 kg with gear on. Ajp makes tight turns, u-turns easier for me. The wr is a real stable bike, even with top speed off 130 everything is controllable and stable. This I haven't tried with the ajp ( top speed is only in the 90 km/h now) When comparing the engines. They are a totally different breed. The wr is powerfull, high rpm engine with a decent grunt at low rpm. Now when you look at the 240 engine off the pr4 it's the opposite. Lots off torque at low rpm , the wr 125 powervalve rush isn't available with the pr4. The engine keeps making more rpm when full throatle but not that much excitement. However don't misunderstand .The power it is delivering is pure traction power. You won't get excessive wheelspin and the net result is that in technical sections you don't have trouble keeping up with the bigger bikes. On open roads it's a different story off course. The engine is perfect for lugging arround in tight section, climbing short steep uphills. I have take uphill sections that I am not able to do with the wr 125. This is not the bikes fault, as I am the limiting factor, but the engine caracter off the wr is more difficult for me . The Ajp let you make small mistakes and will still get you through. This isn't the case with the wr (me driving it.) One other big difference is the range you can do. My wr is empty arround 85 km. With the pr4 I have already made more than 145 km and still had some gas left in the tank. This is a huge time saver when riding long trips! My longest"Balade enduro" was 208 km long. A tank stop and you are good to go. This was a very muddy and wet trip heat approx 17 degrees celsius. Although the engine was completely covered in mud I had no overheating problems. Slightly richer jetting and the oil cooler did there job. It was a combination off fast sections and first gear crowling sections. Again the ajp worked spotless. I changed the oil at 300 km and found very little metal shavings. Shifting already smoothed up. Gear changing and neutral finding is easy. Only downshifting needs a firmer push. Clutch is smooth and easy controllable. sometimes a little sticking when cold started. I use 20w50 oil, so that may be the reason when cold. One thing I like so much is the electrical start. It's so easy I am thinking about removing the kick starter. The kick is not the best design, but in case off a death battery it is a back up starter. The weight between two bike is similar, but when moving the ajp feels even lighter than the wr. It feels really like a mtb. Must have something to do with the gas tank under the seat, As the netto weight is a little more then the wr ( both factory specs) One minor point was/ is the rear brake. The standard pads are awfull. I coudn't lock the rear wheel, disk started to overheat and turned blue. Now that I changed to bendix sintered racing pads everything came together. Wheel locks even on dry road. Still controllabel. I also ordered the Bendix front pads but haven't installed them yet. What I don't like is the rear brake lever. Standard it's almost under the engine casing, however it's easily bend outwards so you have better clearance. It still feels flimsy and I am going to replace it when something is available. The factory told me in email they are working on it, but I haven't heard anything yet. I am going to weld a large triangel on it so my boot has better grip. I feel it's to small and low. (even when adjusted max range) That's the only problem I have with the bike. Off course most rear brakes feel weak when coming from the wr with the super brembo brakes. In the riding you don't use the rear brake that often because off the nice engine brake you have but nonetheless I want a good rear brake. I am also looking for upgrading the levers. I want them to be a bit closer to the bar. Adjustability is limited and I have rather small hands. Lights, battery, electrics seem good so far. Plastiks are not overly brittle. I haven't broken anything and have frequently kissed the ground. For my riding style I really like the rear trials tire. The combination engine, trials tire is giving me so much tracktion. Uphill riding from a standstill is so easy compared to the wr. Front tire is a Michelin enduro competition. A standard tire over here giving descent performance in our conditions. When it is used up, it wil be replaced with the golden216. When driving on the road I am having more comfort than when riding on the wr. The ajp has less vibration, saddle is good. When riding really long trips I wear a padded mtb short under my cross pants. Conclusion: Both the ajp and the wr125 are very good bikes.They serve a different purpose. Wr is a real competion bike and the ajp is not . You can ride it hard , but it's not a hard enduro. I am a middle class rider and like the ajp more. I have the feeling I can ride the bike to full potential and feeling In command. In the same conditions the wr sometimes is too much . The brear brake need some work ( easily done) , other than that it's perfect for me. If you have questions ....shoot. Best, David ps: I have some pictures to post but that is new to me
Thanks for posting your experience. Nice to get another viewpoint than me blabbing my mouth. I agree with you on the rear brake peddle on the PR4, it is not the quality of the rest of the bike and needs addressed. Easy fix. I also learned the same thing about the brakes, replaced the pads with metallic sintered pads and all of a sudden the brakes are very good. I believe the new bikes coming into the US all have sintered metallic brake pads. Again, easy fix.
Yeah thanks David your review it is much appreciated. I know the 125 Huskys so your comparison helps me understands how the bike works. Enjoy and thanks again.
Hello from New Zealand I was online looking for info on aftermarket parts and found this thread. The link above takes you to a thread I started. The bike now has 30 hours on it, easy hours on the motor, but hard hours on the bike, as it's being used as a learner bike for both my 17 year old daughter and now my wife is just starting to learn on it. The poor things been dropped WAY more times than I can count and even rode into the back of my mate sitting on his XR600 (the ife did that one lol) Thing is, other than I need to take the shifter off as it's a little bent, you really wouldn't know, nothing has broken off, stopped working or given any issues whatever. Are they the best bike out there, no. Are they a great bike for the price, imo, Yes!
Pro racer Rory Sullivan thrashed my AJPs today. Man that guy has some skilz. Was fun to watch. He said he really liked how they handled. Guy was dragging the hand guards everywhere. Also popped up over down trees like Garvis. Was fun to watch.
Here is my buddy on his AJP PR5 with a backwards cam recording me on my PR4 and buddy blake on my PR5. Yes, a 3 AJP ride. Super fun day.
Trail looks awesome, as always. You need to stick closer to his rear fender so we can see the bike work . That thing sounds like a whisper-jet!
Same day, I'm on the little PR4 air cooled bike. Super fun little scoot. Bike amazes me with how much torque it makes, lug it around. Does not feel fast but works great.
Kelly I think if you fitted that AJP with peddles you could still trash my butt through the woods Nice vid as per the norm
Doma pipe and big ass pegs ruled. Doma makes it start, idle and run better overall. Adds snap, revs quicker and seems to have gained power everywhere. Power wise it is not huge but noticeable and I feel like I need to gear the bike up now. Pegs lock you in and give you great control over the bike. Was a beautiful day in the NW. Fun stuff. Love how thin and light this bike feels on the trail...
I am a shorter rider and always struggle with my bikes on the trail. These seem a bit smaller and more nimble. I kind of want to ride one someday. Seems like its going back to the xr200/xr400 days for beginner dirt riders like me...
