Metrakit Pro Race 77cc Cilinderkit  Derbi Euro 3 / Euro 4

Voor de echte raceliefhebber en tuningfanaat: de Metrakit 77cc Pro Race 4 cilinderkit is de vierde generatie van de legendarische “Pro Race”-serie. Metrakit heeft zichzelf opnieuw overtroffen door de boring te vergroten van 47,6 mm naar 50 mm, waarmee de cilinderinhoud stijgt van 70cc naar maar liefst 77cc.

Pure performance – Pro Race 4 77cc
De 77cc Pro Race 4 behoort tot de krachtigste racecilinders op de markt. Meer vermogen, hoger koppel en betere acceleratie  en dat alles vooral merkbaar in het hoge toerentalbereik.

Dankzij de slimme uitlaatpoort met 3 openingen blijft de vermogensafgifte mooi geleidelijk, vooral in combinatie met een goede 80cc race-uitlaat.

Onze aanbevelingen voor optimaal gebruik:

  • Versterkte topklasse krukas met standaard drijfstang en slag (Voca Racing HQ)

  • 28 mm carburateur

  • Verstevigde racekoppeling 

Niet toegestaan op de openbare weg / Geen typegoedkeuring

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep

Comfortable and Supportive, but Adjust the Filling
Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D
