1. Fuel Consumption: The increased power output of the WR450F with the big bore kit results in higher fuel consumption.

2. Maintenance: Dual-sport motorcycles require more maintenance compared to street bikes due to their off-road capabilities.

3. Weight: The WR450F is heavier compared to other off-road motorcycles, making it less agile in some situations.

Details:

No generic for mass listings. There are no rings, Wrist pin, cir clips included. The sides of the piston show almost zero wear. It does have a few light scratches and you can tell it had cir clips put in.

ONLY the piston. This is a used JE Forged 98mm piston taken from 2004 Yamaha WR450F. It looks like it may have been installed but not run. I will combine items and give good deals on shipping.

All parts are cleaned and inspected by me. Sometimes the cheapest option isn't shown. All bikes are disassembled using proper techniques and tools. I will reply same day if you message me.

I am parting out this entire bike. All are unique to that. This part is in good usable condition. But sometimes mistakes can happen.

Like I said above, clean and inspect every part sell.
