Was once mostly agricultural but over the last 25+ years, the kids of long time property owners have sold to the highest bidder. This valley is approximately 40 miles long by 35 miles wide. They continue to grow bolder and bolder even with the population exploding all around us in this wide open valley floor. They are definitely not my favorite species of animal. MGoing to apologize in advance to those that have a soft spot for wolves. a buddy of mine had one with a crf 450r motor in it and i have never seen a trx tht is tht quick in torque and top speed.i just wondered which engine is better in the trx body? The first generation engine had a 10.5:1 compression ratio while the second generation had a 12:1 compression ratio. This increased the power from about 33 horsepower (25 kW) in the first generation to over 40 horsepower (30 kW) in the second. In addition, Honda changed the carburetor from a 42 mm Keihin butterfly type to a 40 mm Keihin FCR. This included a more aggressive cam profile, a larger bore with a shortened stroke, a new, short skirt piston and titanium rather than steel valves. In 2006, Honda overhauled the TRX450R engine to make it more similar to its motorcycle variant. In 20, the only interchangeable part between the ATV and motorcycle engines was the camshaft.


Honda claims that it designed the TRX450R engine to produce more torque so that the engine was more suited for ATV purposes. Initially, many people were disappointed because the first TRX450R was very weak compared to the CRF450R. While the CRF450R and the TRX450R share the same displacement number, there are very few of the same components between the two engines.
